Dinghy Ratchet Mainsheet Block Options

When it comes to upgrading and picking a new ratchet block there are many options you can choose from.

Harken 57mm Carbo Ratchet Block - 2135

The Harken 57mm is one of the most popular ratchet blocks on the market with most new boats from Laser and RS coming new with this block. The Carbo design is lightweight at 85g and is durable with a 5-year warranty making it a great option for your boat. This fits up to 10mm rope so is compatible with most dinghies. Harken 57mm Carbo Ratchet Block

Allen 60mm Pro Ratchet with Waved Sheave

The Allen 60mm is a relatively new block with a different design philosophy from the Harken block. The larger sheave allows up to 12mm rope so great for all sheets on most dinghy and keelboats. Having a waved sheave offers up to 40% more grip without adding additional wear to the rope. Allen 60mm Pro Ratchet with Wave Sheave

Selden 60mm Manual Ratchet Block 

The 60mm Selden ratchet block is the most affordable of the 3 with a carbon fibre reinforced sheave over the other block's aluminium sheave this different-shaped sheave is designed to work with a range of sizes of lines. This block gives you the option to turn the ratchet off to have a free flowing block in lighter airs. Selden 60mm Manual Ratchet Single Block
