I agree that the threads on the aluminum plate are likely the weak link, but the plate is pretty thick (0.4”) so lots of threads. Also, that winch is used exclusively to raise and lower the main, so not a lot of stress on it since once the main is up, the clutch takes over. It made it so I could easily raise the main solo from the cockpit with my eWincher while manipulating the boom to prevent the sail hanging up on the lazy jacks. Dave
