The Nautos 92710 is a single swivel ratchet block, port version, with a ball bearing and an aluminum sheave. It is rated for a working load of 850 lb (385.55 kg) and a breaking load of 2400 lb (1088.62 kg). The block is 4.13 in (105 mm) long and weighs 0.81 lb (367.41 g). The maximum rope line is given as 3 in (76.2 mm).
Our take
The ball bearing and ratchet on this aluminum-sheave block are what to look at first. The specs give an 850 lb working load and a 2400 lb breaking load, so you can check them against the loads on your line.
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.
