Securing oars against theft

I cut a cross shaped hole in each oar sized for 6mm chain and secured the assembly to both the dinghy and an inverted 'U' shared frame installed by the local council to store dinghies.

The oars were stolen, including the chain.

Now I take the oars home.

If I were to consider leaving the oars at the dinghy rack I'd use high tensile chain, as used by motor cyclists, possibly of a square wire shape. High tensile chain is hard and hard steel is more difficult to cut, even with bolt croppers. The main issue with HT chain is that it is commonly not galvanised (but would be powder coated).

been considering this lately, to avoid carrying every time. Maybe a hole through the inside part of the handle end, long shanked matched key padlocks through, together on strong point.
 
I use one of these:
RJB Galvanised Aluminium Oar Lock / Clamp (Bolt to Seat)
Obviously not as strong, or smart, as the shiny ones sold by Toplicht but about a tenth of the cost.
I have it set up so that the oars are locked down over one of the locker hatches, so this also gains me some secure, dry, storage for e.g lifejackets.
Being aluminium it was also very easy to drill a hole up from the bottom end, and I have a piece of bungee in there, tied down to an eye under the thwart. This isn't an anti-theft feature, but it secures the oars for when I am towing or sailing the tender. The oars remain accessible very easily, just by lifting and turning the clamp.
 
Any ideas for securing wooden oars to a grp tender left on a beach?
I made captive collars and I use bronze rollocks. A wire strop fits between the rollocks and oar and secures to the dinghy.
The scratched up bit on the oars is wrapped in glass cloth to act as a wear surface. The collars are just marine ply rings I cut and slid on and glassed in place received_1497432757389233.jpeg

I've never come across galvanized aluminium before.i wonder what it's really made of.
Good traditional design but I'd think aluminium is too easily cut to be a serious contender .
My old oars are certainly not worth pinching but I've now gat some lovely German made ones so may have to be more careful .

Yes I think they're just aluminium. And if left in a damp locker it develops a white crusty coating.
But at £6 what do you expect.
It's already done its job at least once for me, I came back from a walk to find the dinghy full of kids who were trying to get the oars out.
