Is the Criterion's running hull any different than a classic?


the criterion hull is basically the 22 classic hull which has changed a tad over the years some work was done on the chines but basically the same.

the criterions are heavier than most 22s

the 18 hull ,22 hull and newer 16 hulls are basically the same layout
rounded keel 24 degree deep vee with full length outer strakes and inner strakes that end around 2 feet from the transom.
the original 16 hull was 24 degree rounded keel but the strakes ended closer to 4 feet from the transom same layout on the rounded keel 19 degree Hornet.

Hello again US Donzi owners. Run 87.5 mph in our annual shootout over here with my Black 540" 22 classic. Need prop advice .Used a 29 TXP instead of my 4 blade turbo fysion 27" Other gyus at the shoot out had the experrience that the TXP is "heavy" takes a lot of power to drive compared to other 29 3 blades. Still running stock bravo x will put a shorty on next year.Whats your opinion about the TXP . When you look at it itīs plenty of material.Very thick. The results from the race will come up in a day or to on the site www.shootout.se (http://www.shootout.se) Now it shows last years event. al the figures are in knots and must be x 1.151 to get the MPH. My friend run 74.8 with his 2004+6.2+wipple+27"bravo. Regards Bjorn:sweden:

I have about 50 pictures of an F-22 so kindly taken for me by Dr. Dan.
For those that don't know, an F-22 is a crossover between
a Criterion and a 22 Classic, having the same raised engine
compartment of a Criterion and a 2+3 cockpit area and built concurrently w/the Criterion.
Judging by those photographs, the hull is identical to my '87 built 22C.
I see no difference at all.

yes George what's your point????


The criterion came first then the f 22 then the 22 2+3 all made at the same time, then the 22 classic during the staples era( no donzi was called "CLASSIC" before Staples ownership) and i would imagine the hulls were unchanged until the molds left florida for goshen ( late OMC era)then the reversed chines came in but that is just an educated guess.
don't forget about the 22s 2+3 with the raised dash panels too most likely taken from the criterion .

[quote=mattyboy;573394]yes George what's your point???? [quote]

My point?
That's simple.
There's the common question that comes up over and over about how
different a criterion is from other Donzis. Whether the fuel tanks
or the tank locations were the same as a 22C (no matter when the were called that).
So, I made the POINT that it is the same hull, and that, just like an 18X,
all the difference is in the deck.

08-02-2010, 10:06 PM
from post 24



Is the Criterion's running hull any different than a classic?

sorry George don't think he was asking about deck treatments.
the Chisholm 22 hulls( all 3 styles of criterion,the f 22 or the 22 2+3 or 22 classic Staples era ) would be the same bottom.

until either Chris Craft or AMH changed the mold. if Barry Eller or Dr Dan have a reversed chine then it was CC if they don't then it was AMH. I have seen an 89 OMC boat built in Fla no reversed chine the same bottom as yours.

I wasn't quite sure we were on the same page or not, the tank location thing sorta threw me i thought you were going down the difference in wetted surface area?? which would mean the factors of COG ,fuel quantity,location,bouyancy of the water ,passenger load,body of water currents and all of that needed to be figured into the equation too ;)

In the 22 class you have Ted running his Ilmore 22- 104 mph
Another Ilmore 22 in the Northwest running north of 100
Yellow 22 on Ebay running north of 100

http://cgi.ebay.com/ebaymotors/Donzi-22-6-Classic-complete-custom-890-hp-100-MPH-/330457084741?pt=Power_Motorboats

All are currently running boats, only Ted (Mr.X) is on these boards.

KY Donzi, who hasn't been around in a while, has a procharged 18. He was running pretty good.

Carl C
08-06-2010, 07:46 AM
It was never my goal to be the fastest. I only wanted the power package that I believe Donzi should offer in the 22 Classic. The HP525 EFI with Bravo XR and shorty lower really brings this boat to life. Low to mid eighties are there when I want it and the acceleration is exhilarating. The 496 package was crap and barely got me into the "fun zone". Now my boat is positively awesome to drive. While I enjoy winning races, and I've only lost one, my aim was to build a reliable mid-80s boat for the Great Lakes. I couldn't be happier with the results! I'm just making an observation that it is not always about top speed. Let Ted and the others run 100 mph if they want to. I've put together a package that can cruise over 70 all day long (or until the credit cards are maxed out ;) ) :)

It includes those models that represent the Classic spirit as well as age. Sounds like there are a few boats out there, send those guys a PM and get them to post themselves.

well considering the 22 classic was not the first donzi 22 "classic"

Greg the hot donzi thread would be a good read I know you are only interested in current members and boats but there are alot of fast ones out there that don't frequent the web anymore

not all classics either Frank C's 22zx and Grizz's son in the 80s

Looks like there are alot of fast Boats out there.
Speedo numbers are one thing because the speedo can be off.
GPS numbers are another thing keep in mind that there is a lag in them.

While some people want to go faster. How many people have gone north of 95-100 MPH in these little 16' - 22' Over & Over not just some one time ride.
There are so many factors.

The real speed is how much brass you have between your legs time & time again.

I would take a boat that runs 75-78Mph @ 4200 Rpm all day long.

GBond
08-06-2010, 05:39 PM
I agree with Carl's post also. There will always be faster classics as the title of this thread suggests. But to get there, you are running on the edge and best have big stones and anuff experience/sense to know when the boat talks back.
These 24* hulls run sweet on your typical lake and river. But where they really shine is when you venture out into the open water of the Bay or say the Great Lakes. A comparable hull would struggle to make a similar impact in performance. And, I'm pretty sure you won't be running 80+

Hi Greg. Still sorting out my 22 classic. Yesterday run 89.55mph at 5700rpm 29" TXP. This took about 730- 750 hp. Here are figures for my speed vs HP:s since last year. would bee nice to here from fast 22:s over there if they got about the same experience.By the way i spoke to the guy with the yellow 540 700hp + 400hp nitrous thatīs out for sale he said that it took way past 700hp to rich 90mph. Last year i had 480hp run 74.8 with 4 blade 27" stock lengt Bravo. Added 130HP nitrous run 80.9. This year Built the 540 with 10.4 comp 234/240 cam and so on . Not dynoed yet Wasnīt time. First run with the same Turbo fysion 27"propp and drive 81.2 close to 5600rpm same speed as with nitrous last year. Then swithed to the TXP 29" RPM down to 5100 speed up to 83.2 Then added NOS Cheater Jet 47/47 worth close to 100hp run 87.5 at the shoot out WWW.shootout.se (http://www.shootout.se) Yesterday Nos 73/82 worth about 130-150hp:s run 89.55mph at 5700rpm The boat feels very stable as long "as under power " I use the nitrous to see how the boat feels with more power. Ball park figure for me in the speed region where iīm seemīs to bee that every MPH takes about 20 hp Thatīs with stock bravo x and maybee not the optimum propp .

Carl . Your boat seems very fast for itīs Power your shorty and propp setup must be very good . Iīm impressed of your speed. I checked my hull this year for straightness and it is very good no hook or anything. I have not dynoed my 540 yet just assuming it would put out around 600hp. At least the speed difference compared to the blue HP 500 i used last year tell me so. Speed without nitrous with stock bravo and 29 txp this year=83.2mph . A shorty would maybee give me like 2 mph so iīm not that far off. But it seems that every mile from now on takes a lot of power to gain. Do you know how much power the other 85+ friends uses for that kind of speed or to go over 90. Itīs so interresting to compare different experiences. Thanks for your anwer. :sweden:

I think I have the boat set up pretty well. Over 85 I am hitting the rev limiter @ 5,400 rpm. The numbers that I thought didn't add up are the 730-750 hp to hit high 80s. I think that should get you to mid 90s. Also you said someone told you that it takes way past 700 hp to go 90. Again, I think that over 700 hp should get to mid 90s. Also, 5,700 rpms seems a little high but not if that's what it is set up for.

[quote=fysis;574658]Carl . Your boat seems very fast for itīs Power your shorty and propp setup must be very good . Iīm impressed of your speed. I checked my hull this year for straightness and it is very good no hook or anything. I have not dynoed my 540 yet just assuming it would put out around 600hp. At least the speed difference compared to the blue HP 500 i used last year tell me so. Speed without nitrous with stock bravo and 29 txp this year=83.2mph . A shorty would maybee give me like 2 mph so iīm not that far off. But it seems that every mile from now on takes a lot of power to gain. Do you know how much power the other 85+ friends uses for that kind of speed or to go over 90. Itīs so interresting to compare different experiences. Thanks for your anwer. :sweden:[/QUOT

I think I have the boat set up pretty well. Over 85 I am hitting the rev limiter @ 5,400 rpm. The numbers that I thought didn't add up are the 730-750 hp to hit high 80s. I think that should get you to mid 90s. Also you said someone told you that it takes way past 700 hp to go 90. Again, I think that over 700 hp should get to mid 90s. Also, 5,700 rpms seems a little high but not if that's what it is set up for.

If I remember correctly, Jim (catch22) who can hit 94 w/his 454, believes he has about 650 HP. And he does it w/a labbed Q4 (I think).

I agree w/P that a shorty starts making a huge difference once the power quotient goes way up. Before that point though, they don't seem to do much.
I think the parasite drag starts going up in a non-liniar manner, and the reduced area of the shorty can give you a real breakthrough.

Since we 22riders have pretty much the same hull . 700 hp.should give us the same top speed with the same setup regarding drive and prop. Maybe my 540 leaves only 560 hp.at 5100. which took me to 83.2 with the 29" TXP. Adding 130 Hp nitrous to about 690 hp took me to 89.5 mph and 5700 rpm, the rpm went furthter then the mph maybe there could be a sin of lost grip due to the stock bravo??? what do you think. I īm no expert of shortys and nosecones but "rumors" tells me that they play a bigger roll at those speeds. The HP:s it takes to go over 90 are still unspoken for since none of those guys have put in a coment. I just spoke to one of the 3 boats thats supposedly are the 100+ boats mentioned in this thread and it could not bee by coincident he run 700hp engine + 400hp Nitrous .

Thanks for the compliments. Except for some minor details I have my boat the way I want it. Some say that the 525 EFI is underrated a bit. It's possibly closer to 540 hp. Running your motor up to 5,700 rpm with juice may be getting you way above your peak hp rpms. I would lose the N2O and prop for closer to 5,300 on the motor. Add a shorty and you will easily be running mid 80s. The shorty also makes my boat run flatter. The only drawback is the increased "air" time in big water. Get the shorty. It was one of the best mods I did to my boat.

Greg I agree with you the HP it takes to this level and further up the ladder is not linear. To move a 24 degree V of 3800 lbs at high speed eats horses. How many at different speed levels?? Havenīt Donzi themselves released any material on the subject,guess they have tried the hull at various speeds and HP combos.

There is less leverage with the higher drive so positive trim lifts the entire boat more instead of just the bow. I can use less tab in rough seas. The roostertail is cool too :). Then there is the factor of having less drag and the pointed bullet comes into play at speeds over about 80 mph. There is also a longer surface area which must have some stabilizing effect as long as the drive isn't crabbing. I am not a fan of nitrous on boats because I boat on the Great Lakes where I need continuous & reliable power for fast cruising. Nitrous is for short runs or you will quickly run out and/or freeze a solenoid open. That happened on my Yamaha Banshee when the N2O solenoid froze open from too much use. On my boat it would just put me on the rev limiter anyway which is probably good because I don't think I want to spin it much higher than 5,400 rpm. You already have a hydromotive 4 blade I believe and you are seeing 5,100 rpm with it now. Put on a shorty and that prop might turn out to be just right ;)! At what rpm is your engine making top hp? If you want 90s I would SC it and forget the bottle. If you get the Imco shorty it has a huge low water pick-up so a sea strainer is a wise addition too.

Thankīs Carl for your information about the Shorty.Really helpful.( I Run a Turbo fysion 27 blade at 5500 without N20) Spoke to the guy thatīs selling Turbo props over here today about my theory about running stock bravo close to 90. He agreed that at those speeds (and before that ) you begun to suffer from "blow out"The prop just ainīt getting enough of water So the shorty would bee like a 50/50 solution as i see it les drag and better grip. Carl you are right about the Nitrous and as i said before i just use nitrous to see how the boat behaves under more power and so far i have not reached the roof by any means.I never planed to have a "bottle " permanently in my boat.

Parnell I think so to. And at speeds in exess of about 80 the stock bravo is not sharp enough in the noose so you star to get a "blow out" the water separates from the drive to much to feed the prop. Let me know how it works out for you . Regards the land whos almost out of summer:sweden:

Fysis, It's a stock 454mag mpi (385HP) with an M3 ProCharger. I run 7psi of boost. I have tried a 29 Mirage + but it was not enough prop. I've have always run a Q4 even before the blower.

Might be that some people are a little "gun shy."

Posting top speed numbers out there for the whole world to see, could maybe, just possibly, potentially cause some difficulties regarding insurance.

Something to think about anyway.

But I suppose that if you were less than honest about the speed of your boat when you took out the policy, and then there was a claim, and they could show you provided them with fraudulent information, they can deny your claim.

Calm (not flat) water
Full tank (just filled up)
Nose down
Just a couple of pounds of boost from the blower.

Need A LOT more seat time before I get the nose up. Gets a little wild when you trim up even at lower speeds. I can see these things can be a handfull full out and up on the pad.

Greg has the first Donzi Classic that I have seen on the Hudson for nine years.
First thing we talk about is Donzi.net

I pulled a 45 ft yacht that was grounded, off the mud in the Alpine Boat Basin.
They won't forget my Donzi X-18 for a few years
I don't think they thought such a small boat had so much power!

probably from not strong enough valves..make sure you replace all of them with manly sever duty intakes and inconel exhaust..if you plan on running the nos you should be running the hell fire rings and maybe have the piston piston ported..

Sorry to hear that FT, but a new high water GPS mark for the Hornet class which is nice! I got a bit closer today, but I am now officially out of wheel and need to go 1" bigger. I was running right at 6800 with The Mule which is not healthy to get these speeds. Livorsi registered 78MPH and Garmin registered 76.5MPH. If I go to 25" should bring me down 300 rpm to 6500. I am not sure what the slip factor is, but it seems like running the stock Precision Propeller "Turbo" Fusion 4 - 24", is the best for speed and control so far. My prop is only an 8 in condition. I thought about a Turbo TXP 4 as another option but not sure yet and running out of weather :yes:

Parnell,
I was able to run river water this past weekend which is unusual for me and contributed to the better speeds. I swapped drives again and was running 1/4" above the pad this time. I still have a slight listing and the ride is a challenge with that small amount of skeg in the water. I was able to hold it for about a mile on multiple passes but no more. There is still a tiny more in it with this engine set-up but the torque steer was not ideal. I made sure to take the passes where a couple of heavy machine operators were watching, just in case The Mule decided to kick back :blub: We still have a month or so to run so more passes to come in November.

If anyone can post Alpha SS dimensions as shown in the Pic #2 below I would really appreciate it.

MOP
11-01-2010, 10:07 AM
Younger needs a raised hatch so he can jack up the BH drive, it will be a lot faster and even more stable. Also the porpoising should be gone with the shorter lever, all you want is the fin and blades in the water.

Greg Guimond
11-01-2010, 06:58 PM
Great MOP, just great......I don't dare ask how much faster Yeller's could be!

This is going to be painful. Actually it already has been painful. I posted my best GPS speed on the last run of 2010 at 79MPH. The Mule, as I've said, has been known to kick back, and this time out The Mule was in a really nasty move. After several passes at 77 I dialed it up a tick and got 79. That was the good news. Hydraulic steering hose burst at top speed, boat did a 90 degree right, yours truly was ejected 90 degree left. Blacked out well before I hit the water and did not come to until I was on a fish boat being brought to the ambulance. :angel:

All that and The Mule couldn't at least give me 1 extra mph for an even 80 to close the year.:banghead: :cussball:

11-04-2010, 09:10 PM
Mop I know that there is more speed, there is no porpoising at all once she is moving. Lets not forget that moving is 40+. All aspects of the bh are positive. The 84.4 posted is as fast as I have gone, yes. But this is not as fast as the boat will go. This boat will run upper 80's with perfect conditions and a lifeline vest and helmut. From my hours in this boat I would say 80 is a great goal for a 16. I have loved ones to care for so running in the upper 80's becomes an issue! For anyone wanting to go for a ride at 80+ hook-up next summer and after the ride ask yourself if you would like to go any faster. Greg take care of yourself.

11-04-2010, 09:28 PM

But yes, skunkwerks season is upon us and that means that the slow boats will be even slower next year. Me? I do "85". Strange thing though, the really "fast" boats never seem to show at a rally and do it in the public eye. So my response is, NEXT! Bring it to to a rally, run it, and then we will all know. The rest of the noise is fluff for the board racers. Looks good, sounds good, but still fluff.

Are you saying that the folks who contributed to this thread by posting there GPS speeds and (sometimes)the props that went with them are not telling the truth? Is this because they did not go to a rally during the course of 2010 and run the same speed under the eyes of a larger group??

Greg Guimond
11-06-2010, 07:12 PM
Carl C, I'm getting to the bottom of it all and it ended up being as simple as a blown hydraulic steering hose on my Sea Star hydraulic system. Initially I thought it was driver error or possible lower unit blow out. I'm not familiar with how pressure is generated in that system yet, and if it increases as the speed of the hull and the associated torque on the skeg increases. It happened at the very top end and the hose severed at the bottom, not at the fitting. I'm pretty complete on all my safety checks but did not catch anything. I was lucky, broke all the left ribs and left shoulder in four places on impact. Could have been worse. Something like this is why I treat the safety stuff so serious.

And if the run is the same weekend as the poker run again there will be guy's that have some fast boats to run with. At least they say they are fast! At one time the accepted speed measure was speedo, them radar, and now gps. I would then think all my time testing, measuring and posting, what I have done was a waste of time and expence. So the next time someone asks how fast my 16 is? The answer will be it is a stock boat, tops 53 or sooooooooooooo!

Now, THAT is what I am talking about! Bring it, run it, hit the speed on demand SAFELY with a crowd, and then it will be real and recognized for what it is. Posting some big
number after not eating breakfast with no fuel in the tank in a down stream current over a five mile stretch at sea level with cold air and colder water in absolutely ideal conditons
is pretty much meaningless. And each boat is different, so set-up will be different for each one too. The benchmarks are just a starting place for testing.

I do admit though, I do enjoy taunting the board racers in the mean time. My intent? Just to have a little fun. Nothing more. Now get to work, the weekend before
Memorial Day aka AOTH 11 is not far off! No excuse not to make it, as you all now have seven month's notice, and we will run them, really run them, as per usual. See you in the Spring

Ghost, thanks. Lot of couch rest ahead for sure.

roadtrip se, I still can't say I understand what you are trying to communicate. This thread is a "one stab" thread. If you get a GPS reading for one stab that works. One stab can mean a second, a minute, or an hour. With current, or against current, loaded with all your buddies and there fanny packs or running with no one else and fumes in the tank. As long as you have a GPS reading to post that's all that is required. Light a roman candle out your arse for a speed benefit, and that works within the "spirit" of this thread. I figured it would be helpful to others to catalogue some of the data as many folks will never post for fear of ridicule but still like to learn.

I like to think that folks on this board have a high level of integrity in general and when posting speeds up in particular. Not everyone has the time to make a gathering, especially some of the overseas posters :doh: As a weedeater, I have taken many trips to the "woodshed" over my short time on the site at the direction of the "elders". I like to think of "elders" as 3,000 posts or more, but hey what do I know, I inhaled way toooooo much ratt a tat smoke this past year :rofl:

Todd, it's not all about being the fastest. For the near $100,000 I have in my 22C I could easily be running over 100 mph. I would also be working on the boat a lot more. I chose to put together a durable reliable package that will run 83 on demand, higher in the conditions you described. My best recorded speed of 85.8 was on the rev limiter btw. Might make a major event some day but you know my situation. I work only week-ends and also don't like crowded lakes on the week-ends. I'm always up for a good week-day run. And it's OK if you are faster.

Greg, my point is fairly simple, posting a number here doesn't mean much, however or wherever you achieved it. Besides, there is a whole lot of fun to be had by running your Donzi at a rally. You don't know, until you go, and then folks will really know, how you go, in the conditions that we all run in.

To your integrity point, never questioned your's or anyone else's here or elsewhere.

It is my choice of what I share here. I stated that I run "85", but we aren't done tuning on this go-around, so the number is meaningless. Happy to take you for a ride at AOTH, so you may see for yourself what it does next Spring. Sandbagging is half the fun and there are plenty of folks here that have not posted a number...

Carl. I never said it WAS about being the fastest. I did state the numbers posted here don't mean much to me, and they don't.

I run an N/A package and it has been a lot harder to achieve results going this route, especially with fuel injection in the equation. So we are similar in this vein for a lot of the same reasons.

As for running at AOTH, you are missing out. Since it is pre-season, we own Lake Cumberland that weekend, so it is not crowded. The only crowd you will see is another Donzi or Cigarette coming your way. Boating by yourself in the middle of the week will never compare. You should try and make it. You have plenty of notice, and I am sure there are several folks that would like to see your boat run, myself included.

at Hale's Bar. Well, if Greg had booked one this year, he might understand the point I have been trying to make about showing up at a rally to see some real performance numbers posted under similar conditions.

Okay, I'll post a number. 87 mph GPS. That was four years ago with a stock 500 EFI going down the St. Clair River. Awesome, until you take the six mph current, the cool fall conditions, the colder water, and the fact I had three ounces of fuel left. And I had just emptied my bladder, which had to make all of the difference.

So according to this exercise, my boat does 87 GPS. There, I am all in with the board racing theme. This was BEFORE I started all of my upgrades a year ago. I can't wait to get to the river again next Spring and post an even bigger number, like maybe 95 or something cool like that. I won't even have to relieve myself this time, because I have lost about fifteen pounds since my last cool weather river run.

I stand corrected, this board racing is pretty cool. Or at least it is until I have to back it up against a bunch of 100mph+ Cig 20's in May. But what the hey, May is a long way off....

P.S. Typically, we have 40-50% newbies at any given AOTH, so it is hardly and "Elder"-oriented event. You are still welcome Greg and Carl and anyone else who finds comfort in this kind of thing. Show it up and back it up. I look forward to meeting you all.

Are you flip flopping on us roadtrip se? If you are going to post a "bench racer" speed then you need to have 2010 data and you need to have the GPS pics to back it up. No need to share your diet details, I at least believe you, but remember this is a "one stab" best speed thread for 2010 so you have some time left to post accurate data :wink:

Sorry Greg, I didn't plow through this whole thread and pick-up on the 2010 and camera requirement, so I posted my personal, one stab, bench-racer best.

Unfortunately, I didn't have an opportunity to take the boat to the river this year, as it was located in Kentucky most of the summer. If you will allow me to post a 2011 number, I'll take it to the St Clair River in the Spring and see if I can get a real tall GPS number then. I'll even shoot pics of my Livorsi and handheld GPS for you, so we have some hard proof.

Good? Just don't ask me to back it up at AOTH.

Carl, one weekend a year. You have been around for 5 years without making a single event, and your a hell of alot closer than I am. Go. You will enjoy the hell out of it.

Greg, you know Todd is baiting you, and so far, you have taken it hook, line and sinker. Nice fishin' Tripper! :)

Todd, quit picking on Greg. :)

I have seen Todd's boat run. It is fast. It wasn't near dialed in when I saw it, he has got more when it is finally tuned. I wouldn't be surprised to see him crack 90 next year.

Now, you can all bite me because when I get my whipple on the 540, you can simple call me DEOO. :bonk:

Is it summer yet ?

Ok, here is another, and the speedo actually says Donzi on it.

Hurray for Mr. X. Now put a Merc Racing 1350 in a 22C. You know you want to......

John, I'll stop looking for the GPS speedo picture I have from a run in an Eliminator at 131. Looks like Rick and Ted have the awesome GPS speedo pic market covered any way. Not to mention a serious, Mercedes-themed dress up package for the engine in Rick's Cig-20. And Ted, I really like that new dash in your 22 Classic. The point has been made.

I think that all the opinions are put forward in good fun. I like to remind myself that as ratttttttt a tat tatttttttt gerbal powered frankenstein 16 I am down just a bit against most of the iron in this thread !!

For those who contributed constructively during the course of this past year to this thread, thanks. Hopefully it offered some insights and was helpful. It certainly was an eye opener for me at least.

Now for you roadtrip se, to come into a thread at month 11, post 160, and open with lines like you delivered, and then continue in a "kick sand in your face" kind of way is being a bit of a board bull, at least in my opinion, if not that of others. I hope that is direct enough because as my grandmother used to say....."if you can't say anything nice, don't say anything". You probably are a decent enough guy but I wanted to give you my perspective because impressions are formed in the first 30 seconds of any exchange, well at least in NYC :wink:

Anyway, just my .02 and hopefully 2011 will be a good one for all. :yes:

After I saw this, I sent a PM last night to Greg apologizing for giving him the impression that my only desire was to blow up his GPS speed thread two months ago. It wasn’t. My intent was to give a different perspective.

A quick story. When I bought my Classic 502Mag-powered boat back in late 2000, I wasn’t terribly impressed with the performance. I had come out of much larger, twin engine boats that just had more punch. So, almost immediately, I started looking for ways to improve the boats performance.

Someone here had rigged a 22 with a carbed, HP-500. He posted an avatar showing a speedo reading in the mid-80’s. I was impressed and started shopping for a 500, landing on a 500EFI, and re-rigging the boat over about a six-to-eight week period. Those were some long, hot hours, loaded with anticipation.

Imagine my surprise when I took the boat to the water and it took everything it had to just break 80. Interesting enough, I pulled the boat to a rally with just an hour of break-in time, and ran with the mid-80’s-500-powered man, only to find out that his boat could just barely get by mine, side-by-side, and I had one hour of seat time.

Very valuable lesson. I had been sand-bagged in a very big way. Fast forward ten years, and this guy is a good friend and helped me last year with several ideas on how to make the boat stronger, better, and more predictable. I utilized almost every one of his suggestions and they work. He knows what he is doing.

I own this boat to go run with my friends at rallies. I think on a dollars per hour and time invested basis, my Formula cruiser is probably cheaper to run, but I keep the Donzi because it is an absolute riot and there is nothing better than running with a bunch of friends in formation.

So again, I apologize for coming on strong, but until you can back-up a number in person at a rally, I will remain skeptical. Lesson learned a long time ago. I appreciate what Greg tried to do here in terms of documenting some performance numbers for folks, but the best way to pick-up real knowledge on what these boats can do in the real world is to go see them run.

Happy New Year everyone!

One more for you, Greg...

Okay, so let’s say nobody is doing any sandbagging. Somebody hit a big one time number and posts it here for posterity.

Why do you think all of the Kilo Runs are based on the average of two directions? To eliminate the variances of the environment and one time factors that might generate a big number. Heck, I have seen the GPS readings on both my speedo head and handheld jump a couple of mph, just by getting the boat out of the water for a few seconds.

So, when somebody comes up to me on the docks and makes a general statement about their top number that just doesn’t quite sound right, I always ask them to do it that day. If they can’t do it on demand, then the big number isn’t real…. Very cool and something to celebrate, but a little misleading in the real world, even if intentions are good...

I think the thread has been fun but I agree with Todd here and I have found that my 80 once in perfect conditions is not nearly as sweet as my 75 in almost any normal lake conditions which I can acheive anytime someone asks. "Rough" water speed, whatever that means to a particular size boat, is the most important thing but would be hard to have a thread like this about.
Since without side by side runs in the same conditions there is no good way to measure real word speed this thread stands as some sort of a measuring bar
