I am looking at a blueprint for a 42' yacht designed by Bill Tripp in 1963. The sail plan lists a Spinnaker Staysail. These are its dimensions: luff=17, foot=18-3, leach=22-3. It is to be made out of 1.5 oz nylon and flown on a temporary stay about a foot ot two inside the forestay and connecting at about 3/4 the way up the mast. Note the short luff and very long foot.
It was intended, I assume, to be raised under a spinnaker to capture air that would ordinarily go under the spinnaker and be lost.
