I have sailed a H-16 with a spinnaker about 15 times in winds to 18 knots with gusts to the low 20s and I was surprised that I never pitchpoled. If you have a H16, it would be a good way to get into spin sailing. My son mailed the kit to the Rabons in New Jersey . He will represent the US in the youth worlds in July. I'm no expert but length of the spin pole bridle is relative in that you need downward prebend in the spin pole so that it does not bend past horizontal with the spin flying. Also tie the spin pole to the underside of the forstay bridle.
