A mainsheet swivel base from Nautos with a short-arm cam, supplied with a 57 mm ratchet block. The base is hard anodized aluminum and runs on ball bearings. Its shackle fitting takes 3/16 and 1/4 inch shackles. Working load is 1100 lb (498.95 kg) and breaking load is 2200 lb (997.90 kg). Maximum line diameter is 0.50 in, or 12.7 mm.
Our take
The ball bearings in the swivel and the 1100 lb working load put this in mainsheet service, where the base can turn as the sheet angle changes. The cam arm is short, so check it against the line you run, since maximum line diameter is 12.7 mm.
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.
