I am a 16 sailor, and these are the least expensive boat to get and keep up, but they are a difficult boat to learn to sail. I would also like to put a plug in for a Hobie 18: An 18 is much easier to sail, hard to pitch pole; they point better, and best of all: in my opinion, they are easier to right. The draw back to an 18 is the mast is heavier, and it takes more time to rig an 18.
Both are great boats!
