You're an idiot. My Mom lived on a 43' sailboat for 15 years, sailed from Florida up to New York, sailed it back down to Florida, cruised around in the caribbean and gulf and all the way down to Brazil and back. She rents boats all the time when she comes out to visit. This club has over 800 members who rent their boats throughout the year. They require sailors to take a keel boat class and become certified if they feel they are not experienced enough to operate their boats.
Renting a sailboat makes a lot of financial sense over boat ownership actually. It costs me $105 to rent a 22' sailboat for an entire day vs owning a boat which would cost tens of thousands of dollars plus slip fees, plus maintenance. Unless you are sailing every single weekend, it is much much cheaper to rent.
Despite your ramblings, many people who rent sailboats actually do know more about boating than many people who own boats. Oh, and despite having a motor on this boat I never used it once.
