Running aground is one of the most common boating mishaps. It can happen to anyone, from seasoned sailors to newcomers who’ve just got their sea legs. The good news is that if you know what to look out for and how to respond calmly, it doesn’t need to ruin your day on the water.
Spot the Signs Early
You might think it’s obvious when you’ve run aground, but sometimes it creeps up on you. One of the earliest signs is a sudden change in how the boat feels. The steering may feel sluggish or unresponsive. If your depth sounder shows rapidly decreasing water beneath the keel and you haven’t changed course, you could be creeping into trouble.
Another telltale sign is a change in speed or the sound of your engine labouring. In lighter boats, you might feel the bow lift as it rides up onto a sandbank. If you suspect you’ve grounded, don’t try to power through it. That can dig you in deeper or damage your propeller.
Steps to Free Your Boat Safely
First things first, stay calm and shut off the engine if necessary. Check everyone on board is safe and wearing lifejackets. Then, assess the situation. Are you hard aground or just brushing the bottom? Look around to see if you’re on mud, sand, gravel or rock. Mud and sand are usually more forgiving and easier to escape from.
If it’s safe, try shifting some weight towards the back of the boat to lift the front (this is known as moving weight aft). You can also try gently rocking the boat or using a boathook or paddle to push away if the water is shallow enough. If you have a dinghy, you could use it to set a kedge anchor in deeper water and winch yourself off. Avoid using full throttle unless you know it’s clear around the propeller and rudder.
In tidal waters, timing is everything. If the tide is rising, it might float you off in an hour or two. If it’s falling, act quickly before you’re left high and dry.
Knowing When to Ask for Help
There’s no shame in calling for assistance if you’re stuck or unsure. The Coastguard or local harbour authority would much rather help early than respond to a more serious problem later. If there’s any risk to your boat, your crew or to navigation, don’t delay making that call.
Use your VHF radio if you have one or your mobile if you’re in signal range. Be prepared to provide your position, a description of your boat, and a description of the nature of the problem. If you’re on a river or estuary, there might be a local rescue or tow service available.
Avoiding Grounding in the First Place
It’s always better to prevent problems than to look for solutions afterward. Before heading out, study your charts, check the tides and keep an eye on the weather. If you’re cruising in unfamiliar areas, slow down and keep someone on the lookout, especially near shallow banks, estuaries or areas with shifting sands.
Using a depth sounder, GPS and paper charts together gives you a better picture than relying on one tool alone. Keep track of your position and course, and don’t assume channels are always clear just because they were last year.
Slowing down in risky areas gives you more time to react and reduces the chances of causing serious damage if you do touch the bottom. Always keep a watch on the tide – it can make all the difference between a gentle bump and a hard grounding that leaves you high and dry.
Running aground doesn’t mean you’ve failed as a skipper. It’s something that can happen to anyone, even the most experienced sailors. What matters is how you handle it. Stay calm, think things through and never be afraid to ask for help. With a bit of planning and awareness, you’ll avoid most groundings – and if you do find yourself stuck, you’ll know exactly what to do.
