There are 3 sailing clubs in Mumbai-- the biggest being the Royal Bombay Yacht Club (RBYC). This is a good social club with all facilities, including a bar, dining, restaurant and sailing. It is located near the Gateway of India at Colaba. The club accepts guest members.
The other two sailing clubs are the Colaba Sailing Club and the Bombay Sailing Association. Both have offices at RBYC. The Bombay Sailing Association has a very good club house across the Bombay harbor and reservations are needed by members to spend a night at that club house. These clubs own boats which can be rented at nominal fee by the members.
