I'm looking to install a ground anchor but am interested in anyone's personal experience in using them.
There seem to be three types (see pictures below):
The Y anchor looks quite elegant and leaves minimal presence when not being used.
The bolt eye can be made cheaply using a fence post spike filled with concrete and a stainless eye bolt
with a washer part way down the thread pushed into the liquid cement, but gives something potentially easy to grind away
The bolt down type again gives something to grind at but the chain is probably more of a target at this point.
I'll be trailering my avon r310 during the summer months and whilst the trailer will be clamped (This is the minimum the insurance requires) there is little to stop two people picking the sib up off the trailer and going walkies.
I'm intending on chaining the outboard to the floor and using a lock over the transom bolts. I'm also considering chaining the trailer to the floor too. Possibly overkill but I'd rather pay a bit extra and add an extra bit of deterrence than find it's gone! I realise that if someone really wants to steal it they will, but there's enough people around during the day to see someone grinding a chain so as long as it requires noise to get through I'm reasonably happy.
Something that maybe looks like this
