Some of your destinations, e.g. the Great Lakes favor a semi-displacement boat with twin engines, others e.g. the Caribbean favor a full displacement boat with a single engine.
Non consensus as to my comment about favoring one type or the other, but you will find that the overwhelming majority of trawlers in the Great Lakes are semi-displacement and the overwhelming majority of trawlers in the Caribbean are full displacement.
If you are serious about the types of off shore places you have listed, Alaska, Caribbean, Baja, suggest you look at full displacement built for living aboard, Krogan's Willards, Ablin's, Defever's etc.
