I received by new Torqeedo and wanted to make it less easy for thieves, so here's my project. See images and descriptions. I will add another cable to secure the handle, and a brass padlock to tie it all together. This won't stop a determined thief with tools, but it might thwart the opportunist (or make a thief choose easier targets). I plan to add my initials in permanent marker to each piece, in a visible place.
