Conventional wisdom says that  you can't scuba dive from a sail boat.  When we first started diving Neal was concerned about sea sickness so he wanted a sail boat with a keel to keep it stable.  We found that the key to diving from sail boats is to lash a portable compressor to the deck and be sure you have a good boarding ladder.

We have combined sailing and diving three times.  Once on a "head boat" in Australia which has sense sunk!  The other three times were on charters in Vanuatu, the British Virgins and the Windwards on our honeymoon.
