GL: Appropriate trawler for Caribbean cruising

[joe]

I can personally confirm that the below described yawing does not occur on
my twin engine N-37 Great Harbour.

I have heard ( but not confirmed) that when a twin screw vessel rolls, the
deeper prop has a bite on denser water , and hense more thrust, thus causing
yawing in conjunction with the roll. Also single screw with long deep keel
and
large rudder tends not to yaw, flip side, it does not make sharp turns. Jon
