Ratchet Blocks


Allen were pioneers in the development of the first AutoRatchet blocks more than 30 years ago.

The clever internal mechanism is designed to activate when the block is under load - as every sailor knows this can make all the difference on a long spinnaker reach or upwind beat.  Years of constant development with the world's top sailors has made the AutoRatchet one of the most reliable and effective on the market. All Allen ratchet blocks are engineered with ball bearing technology and advanced engineering polymers for longevity and performance.

Barton Marine The new Barton Ratchet Block is designed to be used on mainsheet systems and spinnaker sheets on dinghies and keelboats, and for small yachts up to 30 feet.

Schaefer Marine M66-08 Single Ratchet Block, injection moulded long grain fibre body features an anodised aluminium sheave for a light yet strong block.
