A double fixed sailboat block from Nautos with a ball bearing design. The sheave diameter is 39 mm, and the block measures 3.54 in (90 mm) long and 1.73 in (44 mm) wide. It weighs 119 g. The maker lists a working load of 600 lb and a breaking load of 2000 lb. Maximum rope size is 0.37 in (9.52 mm).

Our take

The 9.52 mm maximum rope size is the first number to check on this double block. The maker caps the line at that diameter, so anything thicker is outside the stated limit. The 600 lb working load sits against a 2000 lb breaking load.

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.
