I am experimenting w/ a Harken 40mm triple w/ ratchet which I picked up way cheap on ehay.

I disassembled and swapped the ratchet sheave and mechanism into an outside position. So basically I now have the HSB411 block in triple form, I just don't use the middle pulley of course. I use this block in the upper position in place of the stock Ronstan fiddle. I reeved it as shown in the pic. I am still using the lower stock fiddle/cam for now.

I got to try it today in some pretty stiff and gusty winds. It works great, just love the ratchet. I forgot how nice these work. In light winds just switch it off. In moderate to heavier air it helps hold the sheet position with a light grip on the sheet.

I did find that during those really strong gusts, it does not always allow the sheet to ease out quick enough. I almost went over a few times. I wonder if that fuzzy dacron sheet is just not mean't for ratchet blocks. I know 1/4" would probably run thru the blocks easier, 5/16" just feels better. Any suggestions for mainsheet line upgrade?
