I actually took both USCG and USS nav courses, I have to say that although well-intentioned, my USCG instructor wasn't so terrific...In any case, you may or may not be aware that the Chapman School
is in Stuart, they have both commercial
and recreational classes. Some years back I took ASA
101 and 103 there, and I though the facility and the instructors were first rate. They should be able to give you some info about mooring
in the area as well, there are also a couple of nice marinas
on site or in walking distance.
