Here is Mike's reply regarding the Trapseat Spinnaker. Mike told me before that is was 400 sq. ft. so I stated it as such event the math did not work out. I am going to measure my Trapseat spinnaker and put the exact measurements on this forum. So here is his reply: <br> <br>. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . <br> <br>It is not 400 sq. ft. its more like 300. Mine is getting fixed, but I think it to be 25 ft. luff and just under 15 ft. foot. <br>Its a tri-radial cut and is flatter then most mono-hull spinakers. This is a symetrical spinaker, meaning it <br>has the same cut on both sides. Its for running deep downwind and not reaching much because of the <br>size. In winds past 15 knots, one must sail almost straight downwind using both hulls or its pitchpole city. Reaching on a 16 with a spinaker that big will submurge the leeward <br>hull in a flash. <br><br>
