The Harken 40 mm Carbo Ratchet Block is a single swivel block with a becket. Its machined aluminum sheave has eight facets to hold the line, and Hardkote anodizing protects the finish. A recessed switch, reachable from either side, controls the ratchet. Safe working load is 300 lbs, and the maximum line size is 3/8 inch.
Our take
Ratchet assistance is the feature here: a recessed switch, reachable from either side, lets you take higher loads by hand. With a 3/8 inch maximum line and a 300 lb safe working load, it is a small-boat block.
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.
