Thanks to the ideas from fine skippers here, I recently made a temporary cuddy door out of a Wal-Mart cutting board and flush mounted a Garmin sonar/GPS unit for those days when there's no wind and plenty of time to cruise the lake using a trolling motor. Just sharing the result. It's cool that much of the technology that was once reserved for big yachts or rescue operations is now within reach of the casual Capri owner. I put two deep cycle batteries down below, wired in parallel. Today I ran at 60% motor power for four hours and only used 25% of the battery bank's energy. Of course, I can remove everything and easily put the boat back to its intended configuration when the wind is cooperating to get back to the sport sailing that this boat was designed for. So fun!
