Harken 57mm Auto Ratchet 2625 Single Swivel
Harken have always been considered top of the range when it comes to dinghy blocks and on the RS400 we needed a block for the spinnaker sheets which could withstand constant movement under a wide variety of loads which also engaged as a ratchet block when the load became too much on the one to one system.
Harken's blocks look sleek and are lightweight but also strong and durable.
As the products tend to be at the top end of the price bracket for a block you expect to get great longevity, good customer support and technical advice which is exactly what you get when you buy a Harken block.
The 57mm Auto Ratchet is suitable for spinnaker blocks on dinghies and small yachts and can also be used in a main sheet system.
We have used Harken products on almost all applications on the RS400 and has always been a popular choice on other dinghies we've sailed in the past. They've always been reliable, we would certainly recommend this block and other products as they serve their purpose time and time again.
