Steve, We own a 2001 Pacific Trawlers 40. Its a solid glass hull with 2 SS fuel tanks @ 460 gallons total and SS water @ 200 gallons. The shaft on ours is 1.75" powered by a Cummins 6Bt 220 hp engine. We have the open transom and love it!
I do know that these were semi custom solid boats and seem to be built very well.
in October we will be heading to the Bahamas for the Winter in ours.
