Focused Attention

In order to provide the best experience and maximum personal instruction, WCM typically limits class sizes to 4 persons (except Coastal Navigation - ASA 105). The minimum number for a class to take place is 3 students. Your class WILL BE RESCHEDULED if the class has less than 3 students. There are no refunds. You may have the option of paying extra to keep the class at the scheduled time with less than 3 students. The best way to make sure your class goes off as scheduled, at the price listed here, is to HELP US FILL THE CLASS WITH YOUR FRIENDS!

Best Weather in the Country.... But

While San Diego enjoys some of the fairest and most consistently good weather in the USA, we will on rare occasions have to postpone a class due to inclement weather. This decision is made at the discretion of the sailing instructor and management of WCM Sailing School. If a decision to postpone a class is made, it is done so with the safety and comfort of of our clients in mind. If foul weather is forecast we urge you to contact us for an update.
