Sorry this took so long but Mike the inventor of the Trapseat and the Trapseat spinnaker has been very busy etc. Mike suggested I measure my spinnaker, which I will do this week. So here is Mike Strahles response regarding the Trapseat spinnaker measurements and using it.

<br>THE EMAIL:
<br>
<br>Measure your spinnaker, luff, foot, and report it to your e-mailers. 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. Its a tri-radial cut and is flatter then most mono-hull spinnakers. This is a symmetrical spinnaker, meaning it has the same cut on both sides. It’s for running deep downwind and not reaching much because of the 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 spinnaker that big will submerge the leeward hull in a flash and smaller reaching spinnakers tend not to add much performance to the 16 over the current standard jib and main set-up. Of course a flat top main will also enhance the 16's performance much more than a small reaching spinnaker.<br><br>
