Default Down east / lobster boat guys ?

What would it take to get one of theese to cruise a solid 25K ? (31-35ft) I'm thinking at lease 450hp diesel with 2:1 gear with the biggest wheel i can get under the thing. It seems the average with 250hp is cruise 13knot and the race boats do 65. There seems to be no inbetween.

I dont think a displacement hull is designed to plane, and even if you made one plane the ride would be marginal and the fuel economy would not be great..

Dantilu's boat is a 35 RP but I forget what size Cat that he has. 510 maybe? But RP are wide and are a bit harder to "push" compared to other DE boats.

A 35 Duffy will need about 500-550hp to cruise at 25kts and need to spin a 26-28" wheel.

As chrisrack notes also, I think it would take a lot more than 450 hp. . I spend a lot of time on a friend's Northern Bay 36 FB w/420 Volvo that cruises at 17kts, but through most anything MN can throw at it.

Mine cruises nicely at 14-17kts and tops out at 21-22kts with a single volvo 370. At top speed it's running too high in the water (mostly on the keel) and is not very stable. I would say that some downeast hulls (like mine) are not designed to go 25kts.

Two things from the above -
Henriques are not Downeast boat, they are modified vee's, and all come with twin engines, so they don't belong in the discussion.

As for the Downeast question, I can tell you, you will not be happy with a 31-35' Downeast at 25+ kts. It will be keel walking constantly, and in a seaway, keel walking is both un-nerving and dangerous.
Downeast's are great boats so long as they are used in the manner they were designed, and that typically is up to 21-23 kts max, and a cruise of 17-19 kts.
Those raceboats are special, they have a very short (about 4") keelet for tracking in calm water - they aren't made for or useful for anything but racing.
I am sure a naval architect can make the necessary trade-off in keel length, bottom contour and other elements to get a Downeaster to do what you want, but the truth is you'd be happier if you want to go that fast with a modified or deep vee like a Albemarle, Cabo, Carolina Classic, Henriques or Topaz.

Who said there are no downeast boats in that size that don't get up on a plane???

The 35 Duffy was winning the worlds fastest lobster boat races when it first came out. I think it had the 375hp cat 3208 with a 26 x 26 wheel.

I think it would do in the 30s if I remember right! That was 1982/3ish

My duffy has 200hp and it crused 17kts or so.. It has a tamd41p so its a high turning diesel. It will do it but I rarely cranked up the RPMs

Jersey -

That Henry is by no means a downeast boat. Might be called a DE hull but it is a far cry from one.

You oughta spend some time reading at Noreast.com Lots of very good DE discussions over there by very intelligent people.

I agree with LI32 100%. A 35 Duffy (or any other DE boat) will get very unstable above 25kts. Try to look for a cruise speed at 17-20kts.

That boat looks like it is someones experiment to alter a hull to fit some need. It is not set up in a manor that is typical for use as a lobster boat. Yes, it could be used to get lobster pots but it isn't as practical as a traditional down east design. I can only think of JC boats being production type lobster boats.

I believe they combined a hard chine at the turn to get a unique design. Wesmac would be a downeast. . IMO, A downeast boat has to capture traditional lines and be part of the footprint that carries on that tradition.
