There’s a certain peace of mind that comes with knowing your boat is secure, whether you’re tucked in for the night or grabbing supplies ashore. Every cruiser I know has gone through that mental checklist of "what-ifs" regarding their yacht and dinghy, and it’s a valid concern. It’s not about being paranoid; it’s just about being smart and protecting the home you’ve worked so hard to build.
In this article, I want to share some of the systems and products that can actually make a difference to your onboard security. We’ll explore 7 different layers of protection, from integrated high-tech boat alarms and motion sensors, to simple camera setups that keep an eye on things when you can't.

1. Boat security systems
Starting with security systems, there are companies out there that offer comprehensive systems that incorporate various devices such as sirens, cameras and lights. Some offer pre-set packages, while others allow you to customize the design to create your own marine security system.
These are some of the companies offering boat security system packages.
Something VERY important to look at when choosing a boat security system is how they're wired in. In some the whole system can be rendered useless if just one exterior wire is cut.
2. Security camera's
Nowadays it's not too hard to get a cheap, reliable security camera that you can use to monitor your boat. Many have motion and audio sensors that can send alerts to your device if a person is detected, giving you the ability see what's happening on deck when you're not there, or without leaving the safety of the saloon.
Most security cameras require an internet connection to gain access to the full range of functions, but for many boaters that's no longer an issue with the introduction of Starlink (learn all about that here). Depending on the camera you can also store recordings offline by inserting an SD card.
In the context of marine security, I believe custom activity zones is an invaluable feature to have. It allows you to adjust the security camera's "activity area" so that waves are outside the motion detection zone, meaning they won't set it off.
There are 3 main types of security camera you could have on your boat; wired, wireless and door camera.
Wired security cameras
Wired security cameras are generally the cheapest option because they need to be plugged into a socket or USB port. Depending on where you're planning to put the camera, you could buy one designed for interior or exterior use.
Here are 3 options from Reolink, Ring and Kasa, which along with Tapo are brands I've personally seen being used for yacht security.
Camera | Features | Price |
Ring Outdoor Cam Plus |
| $69.99 on Amazon |
Kasa 2K+ Outdoor Wired Security Camera |
| $44.99 on Amazon |
REOLINK Wired Security Camera Outdoor |
| $54.99 on Amazon |
If you're looking for a simple, cost effective way to start a camera new system, I would recommend Kasa as a good place to start.
Wireless security cameras
Running off battery power, the wireless security camera's are much easier to install on a boat, you just need to remember to keep them charged or get one with a solar panel!
Camera | Features | Price |
Ring Outdoor Cam Plus (Battery) |
| $99.99 on Amazon |
TP-Link Tapo Wireless Outdoor Camera |
| $44.99 on Amazon |
REOLINK 4K Solar Security Camera |
| $149.99 on Amazon |
For me, one of the main downsides of wireless vs wired is that the wireless cameras generally don't support 24/7 recording. This means if the motion doesn't activate the camera, the footage of it may not be stored.
Door cameras
Depending on the type of door you have on your boat, a door camera with automatic person detection can be a useful way to see if someone has come aboard. We know people who have installed them on their catamaran doors or next to the companionway entry, and been happy with the added security.
The Ring Battery Doorbell, Tapo 2K Wireless Smart Video Doorbell and Blink Video Doorbell are all well-reviewed, wireless choice , for a simpler installation process.
3. Intruder alarms
You can install an alarm system aboard that sends a notification and activates lights or a siren when triggered. The idea is to scare off the intruder, placing your vessel in the "too hard" basket.
Some intruder alarms are triggered by the movement of a door, hatch or window opening. These alarms usually have magnetic sensor that sets off a siren when the magnets disconnect. Some are really easy to install, often just needing a bit of double sided tape, while others are part of a larger boat security system.
Other alarms are activated by the motion of someone walking around on deck. The very simple systems just have a sensor you can put outside and a speaker you put inside, while others have Wi-Fi connectivity options that send alerts to your phone.
Personally we don't have a motion alarm installed on our vessel, largely because we already have a living one in the form of our dog! Dogs do add a layer of security aboard, but there's a lot to consider when sailing with pets.
4. Motion activated lights
It seems like a such a simple thing, but a well angled motion sensor light could be enough to deter someone from going any further into the yacht. It can also be handy if you're coming back to the boat at night and need to unlock to go inside.
There are stand alone battery motion sensor lights, like the Ring Spotlight, or you can get one that's integrated into a security camera, like the Tapo Wireless Outdoor Camera or Ring Spotlight Cam Plus.
5. Locks
Living out on a boat you can start to get a false sense of security that leads many to forget to lock their doors and hatches. Personally we always lock ours, and for good reason - we've had unknown people board the vessel 3 times since owning SV Liger. But not all boat have locks or adequate locks, and there's also your dinghy security to consider.
Retrofit hatch locks
Depending on the type of deck hatches and latches you have, they may not be lockable. Some brands have created locking systems that you can retrofit into their hatches, while others have lockable versions.
Lewmar has a hatch lock and key kit which can be retrofitted into any of their hatches.
Southco compression latches and push to close latches can often be direct swapped for a keyed version allowing you to secure the locker.
Retrofit door locks
Most saloon and companion way doors have keyed locks or deadbolts, but on the interior, many cabin doors aren't lockable and those that are tend to be push button locks that can easily be released from the outside. Depending on your needs, you may want to retrofit locks or door handles that are keyed from the inside, to lock yourself in, or outside, to make it harder to get in.
Dinghy locks and chain
Looking at the Caribbean Security and Safety Network, one of the most common thefts I see is unlocked tenders or tenders with thin wire ropes that were cut. As a result, I always suggest locking the dinghy up using a thicker chain. The reason I suggest chain, despite the weight, is because a thick chain is generally much harder to cut, so acts as a bigger deterrent. For the padlock, stainless steel is obviously better due to its resistance to salt water.
As an added piece of security, you may want to add something like an AirTag or Spot Trace to track the position of your tender if it does go missing.
6. Remote Boat Monitoring Systems
If you're not on the boat and want to monitor the vessel against threats like yacht theft, you could utilise a remote boat monitoring system. Among other features, these systems have geofencing and send you an alert if your vessel moves position.
Some companies also offer optional extras that can be used to build a complete boat security system, with add-ons like door contact sensors, sirens, PIR sensors, security cameras and bilge pump alarms.
Here are some of the remote boat monitoring systems on the market.
Just keep in mind many of these monitoring systems are subscription based so there is an ongoing cost to using them.
7. Self Defense
There are few topics more controversial in sailing than self defense. For many, the primary goal is to be able to successfully use the self defense items as a deterrent, rather than having to physically use them on someone.
Here's some of the suggestions other cruisers have shared.
Pepper spray
Bear spray
Flares
Speargun
Boat hook
Machete or knives
Petrol
Keeping your boat safe and secure
Taking boat security seriously is a prudent choice and something you're unlikely to regret. While many sail and motor around the world for years without incident, you still want to make sure you're in the best position to keep your boat and crew safe in the event that someone makes your vessel their target.
