Just a word of caution! Many spinnaker systems have been tried on the H16 with little or no success in improving the H16 performance. From all reports the trumpet system and especially the sail cut and shape of the spinnaker designed by Hobie Europe does add a lot to the performance to the H16, the first system to do so. And the only reason the H16 Trapseat systems works is due to the Trapseats themselves and without the Trapseats it will not work because the lines need to be run off the Trapseats. Hobie USA sells a spinnaker system that absolutely does not add any performance advantage to the H16, but of course they are now going to sell the H16 trumpet system, so do not buy the old system. So my suggestion is to either buy trumpet system from Hobie or some how find out the exact shape of this new spinnaker to have one built with the same shape so you do not waste your money on a dud. I must add that the trumpet system even without the sail is a winner for the H16.
