Has anybody seen the portable spyra base ground anchor from sas, i bought one and they are very good for helping to secure your boat when your on holiday, camping etc. It can be used to secure the trailer and the outboard to make life a lot more difficult for those thieving b------s out there.
I believe the idea behind all these ground anchors is that you'd have to lift and turn round whatever is chained to it in order to unscrew it.
Best bet is to have two so its impossible to do the above.
