Not Fort Knox, just a kayak, stored on the beach in a salt-water environment.
Windsurfing shop nearby had a bunch of boards stolen couple years back and the perp used bolt cutters on the cables.
What I am thinking is the smallest gauge chain that will resist garden-variety, low-end Home Depot/Lowe's bolt cutters.
Is this realistic, or can low-end bolt cutters get through 3/8" chain (the largest size I would consider). If so, I guess I would fall back to the smallest chain that a pair of diagonal cutting pliers could not cut.
Also, there is matching a padlock to the chain..... The padlocks I saw at Home Depot today probably resist bolt cutters at least as much as
3/8" chain, but did not look all that robust in the context of salt spray and blowing sand 24-7. Maybe some sort of bag around the lock?Galvanized, of course....
