Everything else! Regular racers and sailors include RS200, RS300, RS400, RS600, Feva XL, 29er, Enterprise, Topaz, Albacore and Laser 4000. We sometimes split starts into fast and slow fleets depending on the race, but generally all the handicap boats race each other.

handicap sailing fleet at island barn reservoir sailing club 

Island Barn Reservior Sailing Club uses a handicapping system , Portsmouth yardstick, to assign a different rating to each class of boat in a mixed fleet and (at least in theory) gives every boat an equal chance of winning.  We also operate personal handicap (sometimes called a back-calculated yardstick), taking into account the results of the sailor over past races, so an inexperienced person who sails significantly better than previously over a season or regatta can win on handicap.
