My dory has nice varnished floorboards to keep my butt out of the bilgewater. They are a neat fit, but not secured. I don't want to screw them down, but I don't want them to float off in a capsize either. I'm thinking of a strap, or bungee, or velcro so that they can be easily removed for bailing, cleaning, access to the drain plug. What do you do?
