Jeff,
I think they are also very light which will help too.
Allen,
Were the blocks that wore little holes in your sails Carbo Air blocks?

Bruce,
I didn't notice any chafe. I think the Carbo Air blocks have fairly smooth surfaces and that might account for it.

Jeff,
Thanks! The Carbo Air blocks are great. Have you seen any sign of wear on the sail? I've been on boats where they've sheathed the blocks in leather to minimize damage to the sail.
When I was in the Garhaur factory they had some really nice blocks that were built into sail material and you would sow them onto the sail. They could not sell them to me because they were under license to produce them for a Canadian sail manufacturer.

Bruce,
Doyle recommended Harken Carbo Air #57. Other folks have used a smaller block, but supposedly they aren't strong enough for the load. I also used 1.25" SS rings on the opposite side of the cringle.

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.
