Upgrade from slab reef to the convenience of Single Line Reefing. This kit is for B171 booms made prior to 2008. Check the article number of your boom end (aft part). If it is 500-016 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:

  • ø10 mm white/blue 32/3 Polyester line for reef 1. 6+ 25 m
  • ø10 mm white/red 32/3 Polyester line for reef 2. 6 + 38 m
  • 2 composite Single Line sliders that run in tracks inside the boom. 
  • 2 PBB60 Single blocks used as turning blocks and fitted to the outboard end 500-016. 
  • 2 reef shackles
  • 2 composite sheaves for your inboard boom end.
  • 1 ø10 mm x 94 mm shaft
  • 1 Outhaul slider. Runs between the two reef sliders in its own track inside the boom.
  • 28 m ø2,5 mm messenger line to pull the outhaul through the boom

Trial and error !
Number of Items: 1
Just used and had to apply a second coat And still some sun bleached spots still bless through ! I don’t recommend ! P.S. my vehicle is only five years old ! So it’s not like it’s been sun bleached for ten or fifteen years But having said that , For the rubber gaskets around the windows and inside track on the bottom that is black as well And gets dirty all the time , this product works great !
