I have been sailing my whole life and would consider myself a knowledgeable, cautious, inshore sailor and enjoy both cruising and racing. I'm using a Catalina 22 spinnaker because that's what I happened to find on craigslist close to me at a very reasonable price. I'd probably be happy with the stock asymmetrical spinnaker if my boat came with it. The boat I bought was in the best shape of all the hunter 216's I looked at, but was the only one that didn't have the racing package. I have never seen a Hunter 216 with a symmetrical spinnaker and since the spinnaker I have is larger than the stock spinnaker, I should be able to sail faster and deeper than the stock setup.
I bought the HydroTurf with the adhesive backing for $120 but I haven't installed it yet as the boat is currently put away for the winter. At the Newport boat show I saw a lot of sailboats with the foam decking and I liked it so I thought I'd give it a try. HydroTurf seems to be a little stiffer and slightly lower quality then the stuff I saw at the boat show, but I think the diamond pattern will hold a little better. Since the boat will have a spinnaker pole, it will require a little foredeck work which the boat was not designed for so I hope this will help. I won't install it until I've placed all the hardware on the deck. I bought only one 4'x8' piece and that should be plenty for what I want to do. might have a little left over for the cockpit. I'm also toying with the idea of adding lifelines. There are plenty of 22' end of life sailboats out there that would be suitable donors. As stated above, I plan on adding large backing plates to everything.
