Just got done poking around on the donzimarine.com site...I see they offer the 38zr with 1350s :drool:....wonder what kinda speed that lil skudder would put down!!!

Doubt they will ever make one. Look at their price sheets. $911k base with no options. And I've spoken with several ex Donzi guys who said they would never buy a new Donzi. Not much of the engineering/ rigging talent went to NC and the Fountain guys are rigging them. Also read a post on OSO where someone had build a 38zr and said "it wasn't quite put together" Very sad what has happened to the Donzi name. Hopefully someone buys it and brings the company back to life.

That's a shame. Hard to charge premium prices if the results don't live up to expectations. Donzi needs to be very careful about their "reintroduction" or they won't be around for long.

But I'm not their target audience by a long shot, and if I had $1M to blow on a boat it wouldn't be a 38 go-fast, or at least not only a 38 go-fast...

So who are they targeting? Gotta be a pretty small handful of folks that HAVE to have a Donzi and have the coin to buy any of their new offerings.

Of course that is MSRP which no one in their right mind would pay but still seems ridiculous to even ask that. I'm very curious how much Donzi was sold for

Just checked sunsations website. Apples to apples it's pretty even. An F4 (base) with 1350s retails at $967k and a 43zr (base) with 1350s retails at $989k

The 1350 #8 drive package is over 200k. each.

I'm thinking boat manufacturer cost gets a sizable discount but is still $150k. So if you want a 1350 boat your initial parts purchase is over $300 grand for a pair of engines and drives sitting on pallets.

That is a high dollar power package, probably comparable to a pair of 1350hp C30 CATs + running gear for a FBSF.

Glad to hear that the new Donzi isn't pricing themselves out of the market, or is at least comparable to similar builders. Maybe someone will pick up the 38ZR with big dog power as a tender for their yacht...

Back to the OPs question, how fast would that sucker go? Doesn't a 38 with 525s run close to 90? So what does the extra 1650hp do?

I would guess a 38 with 525s would be in the ballpark of mid to upper 70s. Looks like a Formula Fastech 35 with 525s tops out at right at 80, when Boattest tried it.

You cannot compare a Formula to Donzi. Formulas are not known for speed. We have a 382 Formula with Merc 600s and on its best day have seen 86. A 38 ZR with 525s will run 88-90. With 700s it will run 105-107. With 1075s it will do low to mid 120s. I'm sure with 1350s it would push towards 140. I don't think the 38 is made for those type of speeds though. I think it would be a better package in a 43. Our 43 with triple 700s rides unbelievably well. It tops out at 120 and feels very safe. I'm sure a 1350 43 would push 130 fairly easily

Wow, that's quite a difference. Do we know why there would be so much difference between the stepped Forrmulas and the 38ZR? Beam? Weight? Other?

525s get you 85+ in a 38zr. 1075s in a zrc have seen 135+

I can tell you for certain 525's in a 35 ZR will net you 90-92 same power in a 38 I'd say mid to upper 80's 1350's in a 38? Hmm prolly 120-130's maybe a tad more

Donzi's are better designed and more efficient. Formulas are just a heavier boat, more of a luxury speed boat. All boats are going to vary. A 38 formula with 700s will do 95, a 39 cig with 700s will do 105-107, same for donzi and Nor Tech. 38 Fountain will do 115+ with 700s. Yes you can make the argument that a 38 Fountain isn't comparable to the other 38s because of the long beak but Fountains are still the fastest out there, although I can't really stand them.

Interesting.

38ZR 9500 lbs, 353 Formula Fastech 9500 lbs
38ZR beam 8'8", 353 beam 8'3"
38ZR draft to skegs 36", 353 draft to skegs 36"

So far that sounds pretty similar in those regards. Sometimes the smaller boat can be too small, but that usually shows up in deeper draft.

But two things jump out at me as possible contributors to the difference. First, the Formula shows a 24 degree deadrise where the ZR says "variable." That could be part of the "better designed and more efficient" difference mentioned above.

The second is that in the video of the Formula it looks like it has a lot of wetted surface at speed. More than I'd expect. If my boat looked like that at WOT it would mean that it was trimmed all the way down. And trimming up would add 4 or 5 mph right off the bat.

Hmmm...

80-81 is all you will see in a 35 Formula with 525s. We run with a guy in FMO with this setup and he's lucky to pinch 80. A 35 Donzi with 525s will run 92-94

Interesting, thanks for the data. I wonder if the shape of the Formula really keeps a lot more of the bow down in the wet or if I'm just imagining it. (Either way, in the world of go-fast taunts, makes me wonder if anyone calls them "Lastechs." :) )

I still love them though, as far as I know.

My friend runs mid 90's in his 353 Fastech with whipple'd 525s. So that's roughly twin 750s.
edit: yes, it keeps a lot of bow down and he has problems with bow-steer. He's going to change props to try to lower the stern and raise the bow this winter.

Cigarette made a 39TG with 1100's (for those who don't know the only main differences between the 1350 and 1100 are the ECU programming and the fuel injection is a dual plane vs a single plane so it can flow more fuel. The 1100 runs on pump 93 octane while the 1350 requires higher octane. You can make a 1350 out of an 1100 for very little money) supposedly when propped correctly it would be able to run 140 max. Probably closer to upper 130's to be conservative.

I've not ridden on any of these boats, and seen very few of them.
But, once several years ago, I was in my old Minx directly behind a 38ZR @ about 40 MPH.
What I found interesting was how much air was en-trained in the water coming off the transom of the ZR.
Mind you, that was @ 40 MPH......think of the air @ 100 MPH!
I'm sure the obviously excellent venting of the steps has a lot to do w/the performance of the ZR.

That is 100% false. 1100s only need 89 and 1350s need 91.

Also there is a Cigarette/ Skater 39 that use to have 1075s ran 135. It was switched over to 1350s. Not sure what it runs now. Of course this is a one off 39 that was built by Cigarette and Skater

^ It is 89 and 91, I'm not really thinking straight on the little sleep I got sorry.

I'm pretty sure that the "Skaterette" was a Skater hull.

Firsthand accounts from the dial-in drive on the the 38 ZRC with 1075s were hardly glowing. I wouldn't want to be in the same zipcode with a 1350-powered boat without some serious testing.

Can you elaborate on that? I know a 1075 ZRC was very rare. I only know of the black one that is currently for sale. How many were made?

what does the one in the 1000 isles run with the Ilmors?

Only one 1075 boat has been built that I am aware of. As for the elaboration, I don't have anything else to share.

The reality, and I had more funny money than I do right now, the 700 NXT would be my choice. There are several accounts of them running into the mid-teens out there. Nice package, and a few are already running with this power, so maybe you pick one up gently used. Can always dream.
