When the skipper's eyes get very, very, wide, a signal will be sent to a 12-V servo-motor, which—coupled to a worm-drive and a pinion—will rapidly raise the daggerboard.
…you’re catching on, but it’s all been very entertaining.
Theoretically it should work, but in a very narrow band of wind and water conditions…, not to mention learning the recognition of and practicing the reaction to will likely equal or exceed the effort of just learning Sunfish sailing basics.
1) Setting the daggerboard aside, the Sunfish has little built-in resistance to making undesirable leeway—it has some resistance—but given reasonable weather for sailing, not enough to develop a capsizable circumstance.
IMHO.
OK…, next time you are out give it a test. Pull up the board and see what results you get at different wind speeds. I will anxiously await your report on if a capsize moment transition point may or may not exist.
2) "Mousetrap" is simpler, but I propose telemetry: build goggles that can measure—give them wireless capability—and do real-time viewing of the skipper's eyes.
