Easiest pushing large hull?

[BGII]

For a large working fishing vessel in times of $4.50/gallon diesel, which of the larger lobster hulls, 43-46 foot would go fastest with moderate power? Finished in a similar trim and weight.

Assume semi displacemnt cruising speeds of 12-15 knots, loaded the same way. Which would give you the most "bang for the buck" in knots per gallon or which would work the same 8 hour day, pull the same number of traps, run 14 knots between strings and take the least amount of fuel at day's end?

43 Lowell, 45or 46 young brothers, 46 wesmac, 46 newman, 44 or 46 Calvin beal, 45 MDI? Others?

I think the wesmac requires some h.p. to get going. I have always liked the 46 newman, seems to push easy. Don't know much about the others.

Calvin Beal all day.

Too bad your cut off is 43

I think 25 mph with 540 hp isn't too shabby for a 26,000 lb boat

(it's a 42 btw and that was a 3406 Cat with the HUGE heat exchanger that is bulkhead mounted, not on the engine, took 27 gallons of fluid. I'd love to build one with today's power plants below the deck)

Oh, and 10,000 lbs of product on the deck and it lost a knot.

Just sayin'

 

[Overkill]

Of those you listed I would say the Young Bros will sail the easiest and most economical due to it's narrower beam an shoaler draft.

 

[Blitzen]

Give it a little time and the Flowers 46 will be at the top of the list.

That is interesting, could you please expand on the 42/3406/27 gal HE ? Very interesting.

 

[F/V First Team]

OEM 42 with the old 3406 engine 540 hp. Had a heat exchanger that was not on the engine, but had to be mounted somewhere else and plumbed in.

Sent another 42 to Portugal and that one had a de-tuned cat pumping out a whopping 192 hp that did 17 knots. Not sure of the weight on that one, but 15 layers of woven roven and mat adds up.

Sure would be interested in building one with today's layup schedules and some nice power

(hint hint)

i gotchya. did not know about the remote HE

I like the idea of over sized HE and AC. Its all about keeping it cool.

3406 great motor.

there may be something in the works.

Travis,

Build a Spec OEM 42 so we can drool over those numbers

 

[Powderpro]

It was a 43', now it's a 46'? Ya baby. I'm wondering how much for a white hull ?

 

[ripta13]

45 young brothers i used to work on was a pig with 800cat rigged for charter fishing. Capt had to go 7-8kts to get 1mpg. 44 stanley gillnetter did 10kts 10gph and was a wicked good sea boat when she had some weight in her

OEM 42 I'm not familiar with the hull. Who designed her? What's the beam and draft and can it be extended like a Wesmac to 46? Skeg hull I would guess? Those numbers are real impressive. To me, being able to go 14-15 knots when I need to getting 1:1 but being able to loaf at 10-12 for economy is key. Not that being able to open her up to 20 for a few minutes would upset me.......

On the Young Brothers, anyone know anything about that newer 46? Don't see any around and never hear about them.

Flowers 46 huh? Well if they go like the smaller flowers and northern bays that should be a winner. The $$$ scares me without even asking......

No pounding skeg built hull here
Built down with a soft smooth ride.

Designed by Eric White, naval architect

Length, overall: 42'
Length, lwl: 39' 4"
Beam: 14'
Draft at lwl: 4' 8"

I suppose I could cut and extend it another 4 feet, it's easy enough to do.

Tell you what, I'll buy a powerball ticket tomorrow morning and if it comes in, we'll build us the sweeeeetest OEM 42' on the coast. Only requirement is that she needs to be ready for the Searsport races.....

Buy two tickets, double your chances

make it 18" wider while you are at it

 

[F/V First Team]

Why don't we just strap an engine to a barn door and send it down the bay? This isn't some old novi boat that's a rectangle, it's a slippery smelt and there is a reason for that.

Ripta, thanks for the feedback on the YB 45. Surprised to hear that. Must be a heavy boat? Shame, the 45 YB is the perfect size all around and it was one I liked. I guess it doesn't go like their 40'. That hull goes real nice. How did you like that Magna marine 45? Not a true downeast I know but from the vids on YouTube, seems like an easy sailing good sea boat.

Travis, thanks for all the info. The OEM is a little on the small side for me but when the time comes, I'll consider it because the easy sailing part with an economical engine is my number one requirement. Minimum 1 knot per gallon at minimum 14 knots cruising speed with a 350-450 derated commercial engine or it wouldnt make sense. 2.5:1, big slow turning wheel.

It's kind of funny to see all the new boats getting so much power and gunning for 25-30 knots when the price of fuel is at an all time high. An economical large hull that would be able to do lots of work while keeping the profits in the owners pocket won't sell though I guess. Everyone is in such a hurry but these boats were never meant to plane were they? I know they can with rails and modifications but if I want to go sportfishing at 25-30 knots, put me in a 42 Bertram I guess...............(shudder)

Didn't Arvid and Arvin Young used to race their own 45's? How did those boats go? Guess they had V8 Macks...
