Single Person Dinghy / Moth / Blocks / ratchet blocks
Ratchet blocks feature an internal ratcheting mechanism which only allows the sheave to turn in one direction. This gives the user more control to make incremental adjustments to hand-held lines such as jib or mainsheets.
Pro-Ratchet: Featuring a switchable ratchet mechanism to give a precise feel. Simply turn the ratchet on or off with the easy-to-use switch located on the side of the block.
AutoRatchet: Featuring an automatically engaging ratchet mechanism which engages and disengages when the block reaches a specific load. Ideal for a spinnaker sheet system when you want the line to run freely through a gybe.
Lockable Swivel: All of our ratchet blocks feature an additional switch at the top of the block which can be used to lock the swivel in 90-degree orientations or set to 360-degree free rotation.
