Hey guys, My dad and I are looking at new boats uner the 40Ft range, we have a 43 ft easment at our dock. We are looking at both sport fishers, riviera 36 w/ cummings 330 being one, and fast trawlers liek the mainship 34/39. I know the main ship will get a lot better fuel consumption at 8 knots but I knwo we will not go that slow that often especially when we have a follwoing sea. I would imagine in the trawler going at least 11 knots. Does anyone have any experence with the fuel consumption on either of theses boats? Or does anyone have any suggestion on a diesel boat under 40 ft that can goes faster than 11 knots and get decent fuel consumtion... we are big divers and fisher. Any input would be great!
