I came across some pictures of my previous boat, an older 36 ft. trawler. When you sat in the salon and looked across to the cabin entry door you were staring at a big ugly stain in the wood paneling at the corner of the door. The leak problem that caused the stain had long ago been solved, but the stain remained. I spent a long time staring at that stain and plotting how to get rid of it. This is what I ended up doing.
Using 1/8 white ABS I fashioned a plate to cover the stain, including going around the door trim at the bottom. To this plate I then attached a 3 sided box, sized to fit a flashlight. The unit was then fastened to the wall covering the stain. Since the unit had a purpose, to hold the flashlight, it was not obvious that its real purpose was to cover the stain.
