The Nautos 92663 combines a single ratchet base of 75 mm with a cam and a triple block with 57 mm sheaves. It is a ball bearing block, 265 mm long and 120 mm wide. Working load is 1900 lb (861.83 kg) and breaking load is 3300 lb (1496.85 kg). Maximum rope diameter is 12 mm (0.47 in), so keep line within that limit.
Our take
The triple 57 mm block on this 75 mm ratchet base is rated for an 861.83 kg working load, with a 1496.85 kg breaking load behind it. Its 12 mm maximum rope diameter is the limit to check before reeving thicker line through it.
From our buying guide
Ball-bearing blocks give the lowest friction on lines running under moderate loads. Plain bearings have more friction, but handle very high and static loads.
Check before you buy:
- A ratchet block is rated for the full sheet load.
- Any becket's load limit suits the job, since a becket can be rated below the block itself.
- A soft-attach block will be looked after, since Harken warns soft attachments are prone to wear and recommends them only for regularly maintained race boats.
