Chafe patches on mainsail - Hunter 356 / 36

[karellen]

I'm adding chafe patches to a new mainsail on my 356. I have measurements from the boom to the spreaders, but I'm not sure about how big to make the actual patches, as far as height and length. Any suggestions?

Thanks in advance...

My sail maker provided adhesive patches for me to apply after I had a good idea where the chafe would likely occur. After a couple of months, I could see where the sail was rubbing. I think the patches were about 7-8 inches.

Usually you need to use rectangular patches with rounded coreners. It's best to actually locate the patches by seeing where you "rub". It varies depending on vang, out haul and (if you rig a) preventer.

I'd put a temp "sticker" where you think it the patch(es) should be, then move it around until you are sure. Then actually apply the patch in the right place. The patch, if re,over leaves a residue that can attract dirt.
