I installed Harken's small boat single line reefing system today, thank you Santa. The kit recommends 5/16 line to be used. Does it need to be that big? I have the Hunter 216 with about 150 ft2 mainsail. The outhaul and cunningham is 3/16, so why not use that for the reefing system? Well that's what I bought anyway, 3/16 sta-set. And it runs nice in the blocks, but is it inadequate in a blow?Thanks,Dan
