While they may not occur as often as a car or truck accident, boat accidents are still surprisingly common. In the sections below, Porter Simon Sierra Injury Lawyers will break down the most recent boating accident data from the U.S. Coast Guard and go over how and why these accidents take place..

Local Spotlight: Boating Accidents On Lake Tahoe

Before we dive into nationwide and state-level boat accident statistics, let us take a look at how boat accidents are affecting our local communities. Between 2012 and 2021, there were 131 boating accidents on Lake Tahoe, resulting in numerous injuries and a total of 25 deaths. The worst year during this period was 2020, which saw 25 accidents, 10 injuries, and five deaths.

Collisions were by far the most common type of boating accident on Lake Tahoe, with 42 recorded incidents during the 2012 to 2021 period. Meanwhile, grounding and departing from the boat were tied for the second most common type of accident, each generating 13 incidents. Close behind were capsizing accidents (with 11 incidents) and flooding (with 10 incidents).

How Many Boat Accidents Happen Per Year?

On the national level, there’s an average of about 4,500 boating accidents per year, resulting in nearly 3,000 injuries and around 660 deaths annually, according to the most recent U.S. Coast Guard data, which covers the years 2004 through 2023. However, it is important to note that these numbers fluctuate considerably every year. For example, 2020 saw the highest number of boating accidents on record since 2004, with a total of 5,265 recorded incidents. However, just three years later in 2023, nationwide boating accidents dropped below 4,000 for the first time on record, totaling 3,844 incidents.

Focusing in on California, the state saw the second-most boating accidents after Florida in 2023, with 339 accidents resulting in 164 non-fatal injuries and 33 deaths. As a landlocked state, it’s no surprise that Nevada sees much lower numbers by comparison, with 34 reported accidents resulting in 22 non-fatal injuries and 8 deaths. Notably, the rate of injury per boat accident in both states is well above average.

What Are the Most Common Types of Boating Accidents?

Of the 3,844 boating accidents that occurred in 2023, nearly half (1,777) resulted from a collision, whether with an object or another vessel. The most common type of collision was with another recreational vessel, contributing to over half of the total figures (1,053). In California, collisions represented 136 of the 339 total boat accidents in 2023 and 15 of the 34 accidents in Nevada. Other common types of boating accidents include:

• Flooding: Flooding is the most common cause of accidents nationwide after collisions, with 386 incidents. In the same year, California saw 38 flooding accidents while Nevada saw 5.
• Grounding: In 2023, there were 359 total grounding accidents and 206 total grounding injuries. These totals were represented by 41 incidents in California and 1 in Nevada.
• Capsizing: There were 234 total capsizing accidents resulting in 103 injuries nationwide. California reported 17 capsizing accidents in 2023.
• Falls: 227 people fell overboard in 2023, resulting in 139 deaths and 92 injuries. Of these, California contributed 12 and Nevada contributed 5.

How Common Are Boat Propeller Accidents?

While somewhat rare, boat propeller accidents are one of the most severe types of incidents that can occur on the water. In 2023, there were 35 total incidents with 33 injuries and 4 deaths. In California specifically, there were 5 boat propeller accidents. While there were no recorded propeller accidents in Nevada in 2023, this type of incident has occurred numerous times on bodies of water like Lake Tahoe. For example, in 2020, a woman’s leg was caught in the propeller, requiring her to be airlifted from the North Shore. Just a week later, a Northern California man was killed after he was hit by a boat propeller and drowned.

What Is the Most Common Cause of Boating Accidents?

One of the most unfortunate aspects of boating accidents is that they are highly preventable. According to Coast Guard data, the top causes of boating accidents are:

1. Operator Inattention: As we have learned, collisions are by far the most common type of boating accident, and most result from the operator of the vessel not paying attention. In 2023, nearly 600 of the total boating accidents were due to inattention.
2. Improper Lookout: Similarly, many boating accidents occurred due to a lack of observation of the vessel’s trajectory (over 400 individual accidents). When the boat is in use, there should always be someone above board watching to make sure there is no impending danger to the boat, swimmers, wildlife, or other vessels.
3. Operator Inexperience: As of 2025, all boaters in California and most in Nevada are required by law to complete a boater education course and achieve a boater card before operating most types of boats, including PWCs. This new law was passed due to the number of accidents resulting from inexperienced boaters, which caused over 400 boating accidents in 2023 alone.
4. Speeding: As in motor vehicle accidents, using excessive speed can reduce reaction time and increase the severity of accidents, especially in crowded or unfamiliar waters. In 2023, close to 300 accidents were caused by speeding.
5. Machinery Failure: While there are plenty of boat machinery failures that are not the direct result of boater negligence, there are plenty more that are. Boaters have a responsibility to upkeep their vessels to ensure they can retain control and safely navigate our lakes and oceans. In 2023, there were nearly 300 boating accidents as a result of machinery failure.

What Percent of Boating Accidents Are Caused By Alcohol?

Many individuals think that drinking on a boat is safer than drinking in a car, but the data tells a different story. Alcohol is the number one known cause of boater death, contributing to 15 to 20 percent of all fatal boating accidents nationwide, just slightly lower than motor vehicle DUI fatality percentages.

In 2023, alcohol contributed to 242 boating injuries across the U.S. In California specifically, there were 16 total alcohol-related accidents in 2023, which is about the median for the five years prior. Of these accidents, 11 resulted in injury and 2 resulted in death. California ranked second (after Florida) for the highest number of alcohol-related accidents for that year.

The Nevada side typically does not see many alcohol-related boating accidents. However, as our firm has seen, the effects of even just one accident can be devastating. In 2023, we represented the families of two people who were killed by an impaired boat operator on Lake Mead in a wrongful death suit.

When and Where Do Boating Accidents Happen Most?

Time, date, and location all contribute to both the risk of boat accidents and can sometimes determine how severe they might be if they occur. Here are some examples:

Time of Day: Most boating accidents occur between 2:31 PM and 4:30 PM, with 794 total accidents and 442 injuries in 2023.

Day of the Week: Most people tend to take their boats out on the weekend, and the accident data confirms this. In 2023, there were 1,150 boating accidents that took place on Saturday and 892 on Sunday.

Month: Similarly, most boating accidents took place during the warmer months of summer, with 561 in June, 936 in July, and 574 in August.

Location: In 2023, the majority of boating accidents (1,726) took place on lakes, ponds, reservoirs, dams, and gravel pits; However, a much higher percentage of fatalities occurred in rivers, streams, creeks, swamps, and bayous; over 21% of the accidents that occurred in these locations resulted in a fatality, whereas only about 15% of the accidents that occurred in lakes, ponds, etc., resulted in a fatality.

What Types of Boats Are Involved in the Most Accidents?

Beyond the place and time of the accident, there is also data that suggests that some types of boats are more likely to be involved in an accident than others. According to the 2023 data, here are the top five most commonly seen boats in these incidents:

What Percentage Of Boating Accident Injuries Come From Using a PWC?

As noted in the previous section, a personal watercraft (also known as a PWC or jet ski) is one of the most dangerous types of vessels. In 2023, PWCs contributed to around a quarter of all boating accidents, with a total of 995 accidents. Over half of these accidents resulted in at least one injury, as well as 47 deaths.

Who Is Most Likely to Be Injured in a Boating Accident?

Boaters with between 100 and 500 hours of experience were involved in the highest number of injury incidents, with 703 reported injuries. In contrast, operators with no prior boating experience were involved in far fewer injury cases, with only 34 injuries. This doesn’t necessarily mean that experienced operators are riskier. It is more likely that this number simply reflects the fact that experienced boaters are on the water more often and are more likely to own or operate vessels regularly.

Age data follows a similar trend. Operators aged 55 and older accounted for the highest number of boating injuries in 2023, with 491 injuries reported. Meanwhile, operators 12 and under were associated with only 18 injuries, largely because so few individuals in that age group are operating boats.
