are semi-displacement type and therefore are made for coastal cruising and area bit iffy for open ocean use. Full displacement
hulls are designed to go anywhere, and there are not many full displacement
trawlers made. Nordhavn and Krogen come to mind as the leaders in this type.
We picked a Krogen 39 for the two of us (and our dog, of course) and have cruised the US East coast
, Western Caribbean
for five to six months at a time. We have found it to be the ideal (my wife's term) boat for a small family
The cruisers we have spoken with on our trips seem to feel Krogen is the better trawler
for the long haul. This is assuming the boat has stabilizers, of some sort. Because it can be a rolly beast.
We had a Krogen 38 cutter
before this and loved it also, so maybe we are somewhat biased
Hope this helps a little.
