Last time stayed at Futura Yacht Club which has 3 bdrm condos and private docks (bayside). I had 12 Boyscouts in tow and we used Conch Republic for tank rental/fills as well as a couple of big boat dives. I find big boats hetic and schedule driven. Small boats are very low stress leisure paced diving. I miss the amenities...sigh, nothings perfect. Make sure you get a boat w/ some shade and deck space. If you have rudimentry boating skills and are not a moron, you should have no trouble if you take the time to preplan (navigation, preload gps w/ major routes to sites as well as emergency fastest to shore routes-take 2 gps as well as marking courses for compass headings should the satellites fall from the skies; cell phones work fine but a vhf HT is cheap insurance). Put all electronics in waterproof bags/containers-a couple of well aimed drops of salt spay killed my cell. I think the 3 bdrm condos were about $750 w/ two slips. If the weather kicks up and you are determined to dive then maybe switch to Cattleboat. Remember, no matter who is the divemaster, once you submerge you are on your own! The best the divemaster can do is take you to an "appropiate" site and inspect you before you jump.
