Harken 57mm Carbo Ratchamatic Double, (Dual)
Boats such as Stars, Solings, and J/24's use double Carbo Ratchamatics for the dual purpose option of either speed or power. They are used for mainsheets on small to medium-sized offshore boats where power is required for effective heavy-air trimming upwind, but speed is crucial for off-wind trimming and mark roundings. The load-sensing Ratchamatic lets main sheet trimmers ease at the weather mark faster than a standard ratchet does.
Use this with a H402 or H403 swivel arm for a versatile two-speed mainsheet system.
