yuk!

Lots of good courses,

nope.

very
reasonably priced,

cheap, maybe, but WAY overpriced for what you get.

nd you will meet others who have boats and will
probably be more than happy to share their boats and their experiences
with you.

yeah, maybe, could be an advantage, but wandering around boatyards is quicker,
more informative and you meet more people who actually go out on the water.
Still, you can have coffee in a USPS course as some grey haired old man or
woman in a blue uniform tells you what lights to show at night on a disabled
boat with no anchor in a channel with mist forming. You will also learn how to
hit rocks by blinding following a compass heading in a rocky channel in a fog.
And, of course, how many PFD's you need on board and how to put one on.
