Now You Need To Secure Your Jet Ski To Your Trailer

Now that you have your trailer securely locked to your vehicle, you will need to lock the jet ski down to the trailer so that criminals don’t move the jet ski from your trailer and onto their own.

You can secure your jet ski to your trailer or to immovable objects with the following locks

Master Lock Python Keyed Cable

These types of cable and lock combinations are easy to use and effective against any criminal who doesn’t have bolt cutter with them.

If you use an Oxford Boss Alarm Lock with this chain, you will have the added benefit of an alarm sounding off if anyone moves it around. See the review on this lock further in the article.

Heavy-duty chains like this won’t are difficult to cut open with most bolt cutters. Premium industrial bolt cutters could get the job done, but there isn’t much chance they’d be walking around with those types of bolt cutters. They could also use angle grinders to cut through the chain, but it’s very noisy and a bit time consuming for them to take the risk.

The best way to use this type of lock with your jet ski is to run the chain through the frame of the jet ski and around the trailer frame or a fixed object that can’t be moved or broken if it’s not on the trailer.

You should secure your jet ski with a chain like this at home as well. If you don’t have something solid to connect the chain to, look at the wall/floor anchors further into this article.

Nice and small to travel with you everywhere you go.


Additional Jet Ski Security Tips

Use a Jet Ski Cover

Use a Jet Ski Cover

Covering up your jet ski on your trailer and at home with a plain cover will go a long way in deterring thieves as they won’t be sure what they will be taking the risk for.

This is especially true if your jet ski is in your garage and in the view from the street when you open your garage door. The criminals won’t even know in what conditions the jet ski is in or if it even runs.


Use a GPS Tracker

GPS Tracker

Hiding GPS tracking units into the Jet Ski is good for retrieving the Jet Ski if they don’t find it quick enough. But obviously, it doesn’t prevent or deter the thieves because they don’t know that it’s there.

Rather use a combination of the methods above to avoid the thievery all together.


Conclusion: Jet Ski Locks

Securing your jet ski is vital, even if the market doesn’t abound with a wide variety of jet ski-specific locks. At a minimum, employing two distinct types of locks—one for the jet ski and another for its trailer—can greatly deter theft.

The two primary elements demanding security are, understandably, the jet ski itself and its accompanying trailer. To safeguard the trailer, consider a coupler lock or a wheel lock. For the jet ski, a robust chain or cable lock would be apt.

To truly maximize your defenses, combine a coupler lock, wheel lock, and chain the jet ski to the trailer. While it may seem like overkill, such thorough security can make potential thieves second-guess their intentions. Navigating through these layered defenses can be daunting and time-consuming, potentially pushing the thief to seek easier targets elsewhere.

While GPS units and insurance policies are beneficial, they don’t actively deter theft. Their value lies in post-theft scenarios, whereas preemptive measures, like the locks mentioned, work to prevent theft from occurring at all.
