I have a Masters Inland/Great Lakes USCG license with the towing
endorsement and want to upgrade it to include the Near Coastal OUPV
(six-Pac) endorsement. My understanding of the rules are that I will
need a total of 90 days in near-coastal waters in addition to another
test.

I plan to be in the West Palm Beach area in March and would like to get
another two weeks experience piloting something for this purpose.

Anyone have any ideas as to how I might accomplish this?
