there are several schools for USCG license
. In Fort Lauderdale
the largest is Maritime Professional Training on Andrews Ave. Good facility, outstanding staff and they offer all the courses you need from OUPV to 1600 Ton Ocean including all the STCW courses. I've taken several classes
for various renewals with MPT and never been disappointed.
The Chapman School
in Stuart, Florida
has a good reputation and offers a variety of courses; SeaSchool in Fort Lauderdale
is another choice.
