What is the Likelihood of a Boat Capsizing and Sinking?
Boats capsize and sink for a variety of different reasons. If you know how to avoid those situations, you will likely be much safer and still have a working boat. Boats can capsize and only a select few are able to keep the boat from sinking.
US Coast Guard Statistics
The US Coast Guard reported 211 sinking boats in the year 2020. These numbers help shape an average for the number of sinking boats within a year.
Most of these accidents were user error, while a handful happened at the dock. The point is, no boat is safe from capsizing and sinking.
Type of Boat
When looking at ships, these are much higher sinking occurrences at two a week. There are a lot of vessels that go missing, so it is believed that many are sunk. It is estimated that thousands of boats sink each year but the type of boat matters in those statistics.
Understanding the Types of Capsizing That Leads to Sinking
There are two types of capsizing that boaters need to know. These are referred to as a knockdown or a turtle.
Knockdown
Knockdowns are also called flips in dinghy sailing. This is when the sails and mast are touching the water and the boat rests at a 90 degree angle.
Dinghies and catamarans can recover fairly easy from this situation. On a dinghy, the crew members should stand on the centerboard to help balance the weight of the boat. For a small catamaran, you would need a line on the upper hull to help pull.
Boats with keels will act a bit different depending on the situation in a knockdown. The crew can often add their weight to the side needed, but water pouring in certain spots may be too much to overcome.
Turtle
A turtle is when a boat completely turns upside down and is likely going to sink. Dinghies and small catamarans can still turn things around from this situation, provided the crew is able to move the boat to a 90 degree angle from the added weight to the centerboard.
If you have a boat with a keel, this will need further assistance from a professional to help right the boat. Some boats are self-righting, but it varies on the type of keel and boat design. With any other type of vessel that turtles, you will likely need further assistance.
What Causes a Capsized Boat?
Many factors influence a boat to capsize and sink. Most of these should be common knowledge, but it is important to point out these situations so that sailors are better informed.
Flooding
Flooding is the number one cause for ships to sink. As more water enters the boat, the more weight it adds.
Depending on where the water is coming in at will affect the weight distribution of the vessel. This causes the boat to lean or dive down quickly.
Collisions
Collisions with an object or the ground can cause water to flood the boat. Depending on how bad boat hits something makes a difference on how fast the boat will take on water. This also affects the weight distribution, making the boat less stable and to potentially flip.
Larger boats are more susceptible to collisions since they require more time to safely come to a stop. Keep in mind that you can still do the same in a smaller boat.
Stability has Suffered
Multihull sailboats have much better stability than monohull boats. Sailboats with keels are also more stable.
If your boat is neither of those, you likely have less stability and could potentially capsize. With dinghy sailing, these are designed to move back and forth in the wind. This causes the boat to flip since it has less stability than others boats.
Bad Weather
Poor weather is the main cause of a sailboat or any vessel to capsize and sink. Since the ocean can be unpredictable in combination with weather, it creates a scary situation if the weather happens to be bad the day of sailing.
Pilot Error
A lot of times people make mistakes whether they are influenced by alcohol or something else. This is no different for operating a sailboat and the pilot makes a mistake.
Sometimes a pilot misreads the current situation on how rough the waves are and continues to sail when near a port. Other times it means failure to respond to dangerous situations due to lack of experience on the water.
Avoiding Preventative Maintenance
Sailboat owners need to routinely make adjustments and make sure the boat is working properly. Skipping out on maintenance could mean your boat does not function the correct way and you could capsize during unplanned conditions.
How to Prevent Capsizing and Sinking
A boat capsized is not a pretty sight while sailing and hopefully you never have to experience it. A lot of people believe that proper care can make sailboats unsinkable.
However, that is simply not true. Here are some tips to stay afloat in your sailboat and how to mitigate the risk.
Leave the Centerboard Alone
In boats that have a retractable centerboard you should always leave it all the way down while the sails are up. In the event you have run aground do not raise the centerboard. If you need to move the centerboard at all you must lower the sail to help lower your risk of capsizing.
Stay Seated
You should try your best to stay seated in smaller boats that tend to have a lot of influence in weight shifts. The weight shift messes with the boom or other parts of the boat needed to navigate safely.
Be Aware of the Wind
You should always keep your head on swivel for the latest wind changes. Sailors that can effectively monitor the wind and how it affects your boat will be one step ahead of any potential capsizing danger.
What to Do if Sailboats Tip Over?
No matter if you are a yacht owner or pilot on a sailboat, there are ways to help prepare for when a boat is tipping over. If your sailboat were to tip over, you should:
- Try to account for everyone that was on board
- Grab life jackets if you are already not wearing them
- Enter sailboat from bow or stern and never the sides
- Sit at bow and help bail water if you can (if applicable)
- Call for help
