Personally, I use a KRYPTOCABLE which is thick, coated, and sold for locking expensive bicycles. And I lock it with a KRYPTONITE brand U-Lock.

Yes, a battery powered grinder will cut all of these. But they make a lot of noise and thick means more time and greater chance of being caught.

Best defense is to have older, ugly, painted dinghy and outboard. This is why I can't have nice things.
I will put this against your wire anytime against bolt cutters or angle grinder
Also the size matters here a thief will walk past a heavy looking chain and go for the softer option with there bolt cutters up their Jumper

Re: Recommendation for cable to lock dinghy and engine?

Cables (not armored) are a joke - don't use for dinghies or bikes. Not only will an inexpensive cable cutter instantly and quietly cut through them, they will also yield in short order to a thief with a small pair of diagonal cutters "nibbling" through them. A cable won't even slow down a thief.

For when I lock my bikes to the rack on my car I use an armored cable. Not only are they resistant to diagonal cutters, they are too fat to fit in a cable cutter and tend to jam them. What I use:

Regular chain can be cut with bolt cutters but hardened chain presents a more difficult challenge. I used 15' of C4 chain to lock my dinghy and motor.

Nothing will defend against a thief with a battery-powered grinder with a cut-off blade. If the dinghy is locked in an out-of-the-way spot then there will be nothing to stop the theft. In a public place thieves will be a bit more reluctant due to the noise attracting attention, but if they can cut through in a few seconds they may just do so and speed off. I have seen a locked dinghy stolen off the beach in front of a very busy outdoor cafe, with the owners watching - it happened too fast to stop.

I had a SS fitting made to fit through the pivot tube of my 15hp outboard, where a remote steering system can be mounted. One end has a hole for a padlock. Using 2 padlocks, one at the end of the chain to the outboard and one to one of the lifting points in the dinghy, and looping the chain around something fixed and back to the 2nd padlock, or even a 3rd padlock for an end loop, was my daily method.

Most importantly, at the end of the day: LIFT AND LOCK OR LOSE IT! Lifting alone, or locking alone, is not sufficient. Lift the boat clear of the water and chain it to the bulwarks or secure point.


Edit: Buy a set of high quality, keyed-alike padlocks. They are useful for securing all manner of things, and having a single key is a great convenience.

One can readily purchase any length of stainless steel cable used for railings and then just make the loops with stainless compression linkages.

Re: Recommendation for cable to lock dinghy and engine?

The reality is that you only have to have a level of protection a step above what everyone else is using at the dinghy dock. If everyone at the dock is using 4 mm chain and you are using old 8 mms anchor chain, thief's are basically lazy and will go after the easier target. If you are in a country with lots of 2 stroke motorbikes, figure out how not only to lock the gas tank, but to lock the gas cap. So the 8 mm chain weighs a lot? ...... a heavy dirty chain beats coming back to the dinghy dock and finding an empty space where your dinghy was and definitely beats having to swim back to your boat and leaving your groceries on the dock.

I like the locks that go over the motor clamps to deter motor theft. Several motors were stolen at my marina. they tried to get mine off but couldn't.
