This is a good one
in the BVI's and on 38' boats... The BVI's are a great place to learn and the boat size will be ideal to learn on. Here's also a listing
of some of the other schools there.
One other way to get some cheap experience is to offer to crew for free on OPB's. (Other Peoples Boats). In about 5 weeks a fleet of boats will leave Norfolk VA on the Caribbean 1500 for the 10-14 day trip to the BVI's. Many of these boats will need crew. See the website
if this is appealing.
