Your P-16 will perform VERY differently than your new uni I-17.
I can only speak for the P-16 in big air. The P-16 works great solo in huge air with a reefed main and jib. Use the reef points in your main to shorten sail because you MUST have the jib to tack solo over 25. I sailed mine in the fringe of Hurricane Irene at 35++ and the only problem was the cross line linking the jib blocks parted in a huge gust. Then tacking was impossible. The next lesson is to let the speed run up if you MUST gibe. If not, the mast tip will out accelerate the hulls and you will do a spectacular flat-boat pitchpole. You will learn to fly! They'll call you "Prindle bird"!
OK, I-17 guys, what do you do to tack in 30+ with no jib?
