The Harken 40mm T2 Ratchamatic is a great option for junior classes and smaller skiffs that only weighs 25 grams.  This block features a less aggressive ratchet that causes less damage to your sheets.

The automatic ratchet engagement helps with smooth gybes and the spectra lashing allows you to secure the block at the exact height off the deck. The 40mm T2 has a lower 10:1 holding power and suits ropes up to 10mm in diameter.

SkiffRopes recommends the 40mm T2 Ratchamatic for:

• 13ft Skiffs
• 29ers
• Flying 11s

Note: Senior skiff classes should use a 50mm or larger ratchet block.
