I read about it in Cruising World once or twice. Sounded like a good group to join if you're just starting out blue water cruising. There are other types of similarly situated organizations which set up for various routes (NE USA to Carribean, Panama Canal, etc.)

No beachcat is rated for blue water sailing that I'm aware of. Not so much for their lack of durability, but rather the crew's inability to seek shelter from the elements (exposure is probably the biggest killer out there)

Trade your Tiki in for a good used Raider 302 or Stilleto and you could feasibly consider the Bahamas for a week or so of crusing
