Pike hunter sorry to hear about the bastards stealing your stuff.
I used to dock at Sutters I was lucky my canvas was a pain to get off but my neighbor not so lucky he was hit 5 times through the summer. They took his batteries twice anchor life jackets basically anthing not strapped down and a friend got hit twice to. We asked them to put gates up down there or something but it happens every year there unfortunetly.
I think a security gate would help some.
