Starting boating? Nos's guide for beginners.
Is a rather excellent intro to ribbing and boating, I was kinda sorry that I didn't write it....but one day I probably will!
if you get a wheelclamp the get th eone that you thing is the hardest to crack open, probably a Bulldog, but the best I've seen are ground anchors that repkace the wheel.
I am not a thief but I can get a locked SAS clamp off a trailer in about 20 seconds without the keys and without braking it. It takes 10 times longer to do it with a Bulldog
I believe that insurance companies that specify a ground anchor( spike) require this in addition to a wheelclamp.
