[C320-list] Reefing System

[Allan S. Field]

Bruce - Use caution with attaching blocks to the sail cringle.  That said, I
don't know how to do this cautiously.  All I know is that over time, with
the sail flaked on the boom and the movement of the boat in the slip, small
holes were eventually created in the sail due to chafe around the blocks. -

What blocks did you use on the cringles?

Hank,
With that low boat number you have there may be a double block jiffy reefing
system in the boom.
There is something on the website describing this and it may show up in your
manual.

We used somone's recommended system of installing small blocks at the luff
and leech reefing cringles and the reefing line feeds straight thru the boom
eliminating that double block arrangement.
I think it was Jeff Hare that recommended the system complete with material
list.

Our reefing line runs from the cockpit  to a block at the bottom of the
mast,
then up to the luff cringle block
Then down to the underside of the sheave at the mast end of the boom,
Out the aft end of the boom under its sheave,
then up to the leech cringle block,
 and down to be tied off at the bottom of the boom.

We used 1 inch stainless triangles instead of the circle loops that the
original material list  suggested.
It works like a dream.
Lower the sail to a premark on the halyard, pull in on the reefing line and
retension as needed on the halyard.
Shaking out is just releasing the reefing line and raising the sail while
head to wind.
