I have nice teak-framed vision doors on lift-off hinges. The hinges are much lighter than the ones Zacor uses, but I like the setup just the way it is. I only hang them in the slip (might while on the hook, but haven't done much of that yet, still a noob
), for the day or several while I'm more or less on the boat. When I head home 40 miles (still have to work), I drop the boards and lock it up. When I bought the boat, the boards and hatch didn't even have a hasp, and I didn't feel the need to lock it until I spen a chunk of change on a Raymarine e7. Fortunately, there isn't much of a theft problem at my marina. The dock gates are locked, and even though a lot of people will hold a gate open for you if you look like you're going through, you don't hear about any real security issues. Part of that might be the fair number of liveaboards.
