Boats roll and pitch, and many gentlemen have been caught unawares by an unsecured heads lid slamming shut. The catch on our toilet lid failed, and in searching for a replacement I came across some childproof catches for cupboard doors. These cost about £3 for 10: they are plastic so they don’t rust, and could also be used for other duties onboard. A few stainless screws and a small wooden block to get the alignment right finished the job.
