Please help! Just returned to our Bavaria 30 (2007) and the washboard lock was jammed closed. My young son managed to get through heads window and allow us in through one of main hatches. Got the lock off the washboard but the lock is just jammed shut (ie cannot open it with the internal slider either). Any clues and/or idea how to get a replacement? It's a Mobella 064 902. Bit concerned as no way to secure the boat. Thank you! Chris D
