[C320-list] Clew Tension with Reef in Mainsail

[tharrison at innovations-plus.com]

On my sail, there is a 5/8 inch grommet straight below the reef clew. The
end of reefing line goes from the clew down through this grommet and ties
around the boom with a blow line. This prevents the line from sliding
forward.

I do the same but if the loop around the boom is too far forward, and it
always slips forward, you can't get enough pull towards the end of the boom
and the sail is too full.
