Nope; never have; at leaast not the clamp-on type of locks that our UK friends seem to talk about. When I've been on extended vacations, I use a bicycle cable through one wheel and around the trailer frame, in addition to a coupler lock (which are pretty worthless if someone wants the boat - take off coupler and install an unsecured one: 3 or 4 minutes and you're done.)
I figure insurance is probably the cheapest option. There is no security hardware that can't be defeated. Best you can hope for is to make it look difficult enough that they'll pass on to the next boat. But if they want yours, well...
Nos: Did you dig those things up in some Dark Ages Museum?
