As member of the Sailing Club you will have the opportunity to learn how to sail. To be able to take a boat out by yourself you will need to be certified. The qualification procedure consists of taking a written exam. A study guide for the test is available HERE. Then after passing the written exam you will be taken out to the lake and asked to prove your ability to sail the boats. The sailing part of the qualification is craft-specific and is listed in the certification procedures, but the written test needs to be passed only once.
The certification
procedure is outlined more specifically here.
Mark Rice put together a comprehensive review/how to presentation. This powerpoint file is available HERE.
