[PSUBS-MAILIST] OTS transducer location

[Douglas Suhr via Personal_Submersibles]

Good point Alan, wave height is an issue on more than one hand with Snoopy
(as I'm sure you're aware).

BTW, we're starting to look seriously into building or buying a barge for
the Keys. We've got to get Snoopy out to the oceanside more quickly than by
towing her. ~ Doug S.
