Full displacement hull running near hull speed. It still has its fishing license and lights, its probably running with an empty hold. Nice boat but not enough side decks for me - love raw aluminum!

Sorry, wrong photo- Eric, here is a bow shot, in my opinion Mark and I have boats with different entry shear. Al-Ketchikan

Xs,
This hull has chines and very little keel aft. Not sure how to classify it. I also love the raw aluminum, grew up on it and made a living on it for awhile. Freshwater.

After viewing the bottom of this boat, it would appear that it is a SD boat with potential of a good rate of speed, if that were desired, with increased horsepower. Not knowing what the current engine is can only assume it to be of economics first and speed second in consideration of need.

for sure Mark and I have a completely different entry. Our boat has a finer entry with a greater flare.

All things equal, the 'bulk snout' of the alumimun boat reflects a very forward breadth carried as far possible causing a wide blunt bow. MHO

Damn! starting to sound like Eric, and as an expert, I fall far short of the 'Man" (This is intended as a complement)

Compliment accepted somewhat gracefully.

I suspect that the Lone Wolf has been extended. Would be quite easy to do w those straight hull lines. That may also explain the bow down (slightly) trim. The engine wasn't moved aft to maintain the original trim.

Now I'm wondering if they are the same boat. Looks like they've got 30,000lbs of fish on board in the first photo and running light in the next pic. The names are different in the last boat but that wasn't a red flag to me as names change. No I think it's the same boat. The fishing (ADFG) number is the same.

Al I just noticed your Marben is 27'. I thought it was 29 like the Prairie.

Eric,
Same boat, notice the name changes but the numbers don't. Not stretched, built as 42 in Astoria Oregon and still 42. A six foot swim platform has been added and I doubt the hot tub was stock, but both are aft so not helpful in explaining the bow wave.
Al,
Powered by 400 Cummins CTA 8.3 but supposedly only capable of 11 knots top end.

Nice HP. but it IS a 42 foot boat. I'd bet weight is a big factor. All the added amenities one desires particularly when you add a hot tank???? Wow. best stay close to the 8.3 till the price of fuel comes down

I think I have a virus that causes me to like many boats I see. I went with the one I did partly because it will likely be easier to sell when I am done with it than the aluminum one offs would be. Owning two boats in this size range is temporary......that's my story and I am sticking to it......for now.

Do you speak from experience?

I burn jet fuel for a living, and we care a LOT about burn.

I agree w bayview. Experience? Sure. I've seen lots of tugs w the "bone in their teeth".

Jet fuel? You mean kerosene? That's what I burn in my Wabasto. Kinda stinky but I burn very little.

Saying tugboat captains don't care" about fuel use is putting them too much at one end of the spectrum. Sure they care. everyone does. They also care about getting to the job quickly, and too many delays will mean the loss of $ earned, so they put their cares about fuel use behind their cares about getting to the job in a hurry. Besides, they spend a lot of time at low speed once the tow is engaged.

The large bow wake is caused by the slow speed and a blunt bow, so it's sort of like a barge pushing the water. Our boat is built on a commercial trawler hull, redesign as a pleasure. The bow flares to the full beam with in 10 ft pushing water.

However the water line is 51 ft so hull speef is 7 to 9. Also a dry ride, not much water over the bow as the bow has a large flare so the water is blocked pushed to the side. Also the large flare so thr bow does not sink as deep and a quicker recovery.

The 400 hp 8.3 puts out almost identical hp and fuel burn at 1400 rpm as my 250hp 8.3. That picture shows me at 1400 and about 7.5 knots. You don't need to use more power for trawler speeds.
At WOT I get about 10 knots at 250 hp but the noise is intense and the fuel burn is breathtaking.

Well the Thread creep is well underway-Y-Knot!

As the OP has gone off on another course regarding bow waves and such, I came across this as I was surfing another subject. It seems appropriate to share with the crew:-
