Great job on the addition of the ships wheel to your Sun Cat. If you haven't figured out a brake you might want to go to a overhead door shop and look at a set of brake shoes for a commercial door opener. They look very similar to the brakes on Edison wheel setups and aren't for BOATS so may be cheaper. You have done lots of inventive modifications to your little ship, would like to get down to the nationals to see it some year.
