The door latch on the main cabin door of our boat seems to have broken. I was in and out of it all weekend and everything seemed to work fine but when I got home on Sunday I couldn't get in. The lock works but when I pull the latch the bolt won't move. All my windows are shut tight so that's not an option. Anyone have advice on how to move the bolt from the outside or how else to get in to the boat? It's a 26ft Hewes Pacific Cruiser.
