Upgrade from slab reef to the convenience of Single Line Reefing. This kit is for B250 booms made 2008 or later. Check the article number of your boom end (aft part). If it is 500-043 this is the right kit for your boom. 

Instant reefing with Single Line Reef

Single Line Reef is made practical and reliable by Seldén. All you do is ease off the halyard to premarked reefing points and then haul in on the reefing line. The luff and the leech are reefed at the same time. A system of guided blocks inside the boom ensures that the lines do not tangle. The system has a 2:1 gear ratio for effortless reefing, without having to leave the cockpit.

The kit contains:

• ø12 mm white/blue 32/3 Polyester line for reef 1. 8 + 31 m
• ø12 mm white/red 32/3 Polyester line for reef 2. 8 + 47 m
• 2 composite Single Line sliders that run in tracks inside the boom.
• 2 reef shackles
• 6 composite sheaves for outboard- and inboard end
