1350s in 38zr

[tnc110]

Just got done poking around on the donzimarine.com site...I see they offer the 38zr with 1350s ....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

[Indyblackhawk]

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+

[osur866]

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...
