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 reef shackles
  • 6 composite sheaves for your outboard- and inboard boom ends.

Great for creating a workspace
Color: Grey
I needed a room divider that could be easily folded for storing to put behind my chair during my work calls. This works perfectly! Was very easy to put together. Lightweight but sturdy enough that it won’t fall over.

Base part of it
Color: Black
Even though I kept this it’s very uncomfortable because of the way the base works . They are very long at the bottom and it’s hard to open and close

Great room separator
Color: Black
The panels are much longer than we expected! We only needed 3 of the 4 proivided. It's slightly flimsy, but holds together nicely. The screwdriver that came with did not fit the screws, but luckily we had a Phillips head. It's very lightweight. It is definitely a good value for the money.

Room divider
Color: Black, Color: Black
It was much simpler than anticipated. I don't think it's very sturdy and it lacks weight, but it's attractive.
