If the courses are from the ASA
or US Sail you are getting a standard product and a certified instructor. They have a track record
of teaching sailing the right way. My wife and I learned on a Capri
22 and a J 22. I think they are a great boat to learn keel
boats. A 32 ft boat isn't as responsive and you'll learn from mistakes
quicker in a smaller boat. They still are keel
boats and so more like what you might want to Cruise
just smaller.Sunfish and other small boats are fun to sail but are not keel boats.
Class size is key. If the class has more than 4 people forget it. You won't get enough time handling the boat. there are classes on big boats and they load up 8 people and charge the same price
for half the time at the wheel
. It;'s good to watch others a bit but having one on one with an instructor helps the most. 4 works for a class size max. I would pay extra for just 2.
Good criteria is talk to the instructor that will teach your class. Some people get along better than others and getting along with you matters more than how many friends they have.
Last criteria is to find the way that makes it the most fun. Adding some days in a nice location makes the course a whole vacation
. Sailing is mostly about having fun and being safe. It should be much more fun than just a class. You should come away excited about sailing.
