This Harken Carbo Ratchamatic HTE block 57 mm is an automatic load-sensing ratchet block for efficient handling of sheets and trim lines on board.
The block rotates freely in both directions at low loads and automatically engages the ratchet mechanism as the load increases. This provides better control while sailing without the need for manual activation.
The HTE version features later engagement than standard Ratchamatic blocks, allowing for longer free-run and smoother operation in situations with varying loads.
