Do you have any guess what the cruise speed would be on the Cummins
powered twin?

17 knots

------------------------------------------

My initial guess was 16 knots but I think that may be high due to the
hull. I just don't know for sure.
A Grand Banks is supposed to have a modified "V" hull (I think)
however the one we had before was so underpowered I can't be sure how it
would perform with the added horsepower and twin engines. The one I am
looking at is also a bit heavier.


Actually, I overstated. That would be my guess as to WOT speed. I have
some familiarity with a similarly sized semi-displacement trawler with
two slightly larger diesels and she'll do about 20 knots, WOT, and about
17 cruise. I think 14-16 cruise, right about where you estimated.
