Or just buy a boat the comes with a spinnaker from the factory
Hope to see you on the ice this winter. I want to get on the Crack X ice boat with a GPS to see how fact we can go! I'll even scoot out on the windward plank for some extra righting moment. I had a blast when when I sailed Eric's boat. I have an extra Hobie 14 I am fixing up to sell and may have to put the funds into an ice boat.
