[C320-list] Second Reef Line Arrangement

[Dennis Cookson]

Hi Mark,

Thanks for the detailed description of your set up, very helpful. Interesting that you used a soft shackle for the dog bone - can you remember the Dyneema diameter used?   
It sounds like a lot of line to haul in, but it does have the benefit that you don’t need to leave the cockpit to deploy it.

I have a clutch available for each reef line, as the lines are set up as per the 320 handbook with the mainsheets fed into the jam cleats rather than through clutches. It’s perhaps not ideal but typically at least one of them will be on a winch.
