Allen Slingshot Mainsheet Swivel Jammer Complete With Ratchet Block

The A5266 Mainsheet Jammer from Allen Brothers is an ingeniously simple solution to a common sailing problem.

Most people who have sailed a dinghy with a centre mounted mainsheet system will have come across the age old issue of the mainsheet jammer not rotating to the correct orientation after a tack or gybe therefore causing the mainsheet to get wrapped or twisted. This hardware malfunction slows the manoeuvre and can lead to a lost race, or in rough conditions a capsize.

Standard mainsheet jammer systems usually have the block centrally located above the swivel meaning there is no turning force to swivel the block and jammer to the correct angle. By moving the block outward from the swivel and angling it away from the cleat, the new A5266 “Slingshot” mainsheet system creates turning force on the block and jammer meaning the cleat will always be forced to point away from the boom and towards the helm. This prevents the sheet from wrapping round the block and gives extra control for fast, smooth tacks and gybes.
