You do need running backstays
to counteract the forces imparted to the inner forestay.
I cannot agree with several of the statements above. Based on 20 years sailing our cutter:
- our three staysails are designed specifically for beating and that is all they are ever used for. Hard on the wind
in 25 knots apparent the overlapping staysail provides 2 degree better CMG, 5 degrees less rudder
angle, and 3 degrees less leeway than with a 90% RF genoa
. The 120% genoa was custom made by North Sails
to provide good windward. performance in 20 - 25 knots apparent when furled to 90%. The genoa is not a yankee in my opinion - but the clew is five feet off the deck
when sheeted hard.
- We never use any of our staysails for reaching...and we've done a lot of reaching in 15 - 30 knots apparent in the ocean.
- our rig was designed to be sailed with no running backstays
to support the inner forestay which is 8 feet aft of the forestay tack on a boat with a 17' J and 32' waterline.
I do agree the storm jib on the inner forestay is a brilliant sail in more than 45 knots
To the OP:
Is it possible the inner forestay has been removed or is tied to the mast
where you have not noticed it? When we secure our inner forestay at the mast
it is almost impossible to tell the boat is a cutter. The only sign is a small stainless tang where the bottom of the hyfield lever attaches.
Our C&C 40 had a removeable inner forestay.
