I was thinking of a 38' Wesmac with a John Deere 4045 135HP diesel for cruising. What would a cruise and top end speed be along with fuel burn rates? I will be a retired sailor so 8 or 9 kt cruise would seem fast to me. Efficiency is a major consideration.

I am sure you would get 8-9 knots (given the math) that that hull would probably burn 3-4 GPH with a big block at that speed which equates to 60-80 HP and your rig would be lighter.

That said, I would go with a bigger heavier displacement hull for comfort and space if that is all the speed range I wanted to go. Would be happy to sacrifice another knot or two in this interest and go full-displacment. Plenty of older trawler hulls out there cheap for a refit that would be more cost effective than a Wesmac kit.

Thinking 120 HP = 6 GPH and I think that most hulls in this size are kind of in the 8-10 knot range at that burn. Once you start lifting these hulls the efficiency trends down fast, and you are already past hull speed at 8 knots

You might run your idea by Glen Holland. I think his 38... hull will push easier than the Wesmac. There are displacement trawler type hulls out there that would do an acceptable job in the 8 to 9 kt. range and not burn much fuel.

I dont know of any true displacement hulls in the 38' range. Who makes them or used to make them?

If was was looking for a 38' cruising boat at @ 8-9 knots cruise it would be a Calvin Beal 38', Duffy 37, Wesmac 38' or maybe a Flowers 38'. The Holland 38' are the prettiest but they all have engine boxes and how that will impact your salon for cruising. My guess is you could throw a continuous duty rated JD or Lugger in the 150 hp range in the others with no box and good fuel economy. Take look at this the length of the top and which hulls look good with long cruising style tops. A long top on the wrong hull will be almost impossible to resell...too many people try and take a 38' foot boat and squeeze the interior volume of a 42'. Then wonder why they get 40% resale value 4 years after they build them. Sounds like a great project...

Sorry, didn't mean to imply that all Hollands have engine boxes just most that I've seen. I believe there's tuna boat for sale in the Portland area with no box that looks great....named Valborg maybe?

My buddy has a 38 Holland 3126 no box but a step. He had a 650 Mack in the boat and that did have a box.

Nice 38 Wesmac

FVSD- Thanks for posting pics of the "Greyback". That's a beautiful 38 Wesmac; Stewart Workman finished that boat, it's a beauty. The Wesmac lines are the most appealing to the eyes (in my opinion).
