Kickup Leeboard - I put the dagger type leeboard on because it was so simple to install. I ran the board aground a few times and it would have been neat to have a kickup leeboard instead. Paddle Holder, Rudder Holder - Store other essential item on the boat all the time. While at it, might as well make on boat storage for everything I have to take. Maybe a step attached to the stern, or a loop of rope that I could get my foot into.
Some people build steps into their rudders.
The sun is a killer out here in the summer. The sprit sail is so high I can see making a bimini top to sail in the shade. My 16' mast wasn't that hard to make, but it was kind of a pain to haul around. Looked like a jousting stick on my roof rack - a 12' mast would fit inside on the floor of my minivan. Race - All boats start from the shore.
