The Nautos 92459 is a single block that mounts through the deck, with an aluminum sheave and a heavy-load rating. It measures 2.95 in long and 1.18 in wide, with a hole spacing of 2.28 in. The sheave is 1.10 in across. Working load is 510 lb and breaking load is 2000 lb, and the whole block weighs 0.10 lb. Those are the figures to match against your line and your deck cutout.
Our take
The 2000 lb breaking load sits about four times above the 510 lb working load, so the rating leaves clear room before failure. The 2.28 in hole spacing is fixed, so check it against the deck cutout before drilling.
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.
