I think a good check list would help. Wind instruments are nice but in my opinion not necessary because you do not know the how the boat handles. You can tell when the boat is overpowered and let the traveler out and suck in the jib. Then reef the main. Mono hulls are much easier to read (weather helm etc). Cats are a different thing altogether. Wind instruments are more important here because you do not get a lot of feedback. Just my two cents. BVI sailing is easy I think the longest sail is Leverick to Anageda or to Jost. All the Best
