Hmmm.....

They may only be avaible through a boating supply house, then. IIRC, they are on the Coast Gaurds very-strongly recommended list. It might be that in someplaces, you need to have a "master's liscence", or what ever it is called to command a larger vessel.

Dunno, this is just me sharing my guess. I know a little about larger boats- they are pointy at one end; the propulsion is on the other; and if the bottom is in the air, you have a problem. <img src="/images/graemlins/smile.gif" alt="" /> Small craft is about my limit.
