    Any thoughts on lengthening my Repco to 40 ft and installing an Qsm 11@ 610 hp. Does anyone know of a 37 Repco with high hp? How well did it move. Looking for any and all comments, I would love a 40 H&H just not sure if the wallet will allow that at this time.

    Never heard of a lengthened Repco, who would do the job? What is the beam of the 37?

    Beam is 12.6 and tappers just below 10 @ the transom. Myself and an awesome fiberglass friend could perform the work.

    Going to 40 feet with only 12.5' of beam may cause the boat to roll a bit more. Normally the length to beam ratio is kept to 3:1 or less. Newer designs are down to 2.7:1.
    My old 30 Repco had a 3.15:1 ratio and would roll you right out of the boat on the drift.

    Narrow makes a better seaboat all other things being equal.

    They have been trying to sell one of facebook that they lengthened and widened out, with a 610 Cummins, Uncle Bucks Boat Shop. A friend has a widened out 37, and it made a nice boat. They didn't change the main bulkhead, just made the width hold the whole way. Gary Kief had the old 37 mold , and it was widened, and I only know of one hull that was pulled , but they could have done more.

    There were 2 of them in a nearby harbor a decade ago. One had a 225 Deere, the other a 435 Volvo. I think they both performed about the same. The 225 Deere looked better going thru the water as it wasn't as heavy, and the bow lifted more.
    You might gain a knot going to 600 hoss...

    Just curious how do these guys widen downeast hulls? Lengthening makes sense but when they widen where do they cut? Do they rebuild the keel? Make two cuts? Redo the whole cabin trunk? I just don’t even know where they would start on a project like that.

    I believe you cut from the steering bulkhead back toward the transom along the stringer. Both sides with the transom removed. Stretch it apart and fill in the gap with glass. New transom I suppose. A novi was widen'd in Little Compton recently, heard it came out nice.

    They sorta described it in that link, but made it sound simple like fixing cracked drywall
