3/8" NO! Huge and much larger than needed - and likely will not fit with the sheet blocks and jib sheet winch cleat/clamcleat. At the most 5/16", and as I wrote earlier 1/4" is really appropriate for a M17/15 headsail. Use 5/16" for the _mainsheet_ (how Jerry set up the boats). :: Dave Scobie :: M6'8" #650 :: SV SWALLOW - sv-swallow.com :: former owner M17 #375 SWEET PEA - m17-375.com :: former owner M15 #288 SCRED - www.freewebs.com/m15-named-scred/ On Sat, Mar 7, 2020, 9:50 AM Mike Z <speedernut2@gmail.com> wrote:
A rookies take.
Lighter the better for light wind.
Heavier is nicer in the hand.
I would lean to 5/16 sta-set, but 3/8 might be more practical.

I need to add a missing jib sheet. The existing one looks to be 7/16" diameter. Casey (This Old Boat) recommends polyester double braid for sheets ("Period."). A sail-rite document ( https://www.sailrite.com/PDF/Rope%20Selection%20Recommendations.pdf) has a table of recommended diameters, and it looks like 5/16" would work for my M17.
Does that sound reasonable?
