Boat Laws in Maryland (2026): Rules Every Boater Must Know

Most people jump on a boat and never think twice about the law. Seriously. But Maryland takes boating rules seriously, and the penalties for breaking them can be steep. Whether you’re cruising the Chesapeake Bay or paddling a lake, you need to know what’s legal.

This guide covers everything: licenses, registration, life jackets, speed rules, drunk boating, and more. Let’s break it down in plain English.

What Are Maryland Boat Laws?

Maryland boat laws are rules that govern how you use watercraft on state waters. They cover who can operate a boat, what safety gear you need, and how fast you can go.

The Maryland Department of Natural Resources (DNR) manages these rules. The Maryland Natural Resources Police (NRP) enforces them. They patrol the water just like traffic cops patrol the roads.

Pretty much any body of water in Maryland falls under these laws. That includes the Chesapeake Bay, rivers, lakes, and even the Atlantic Ocean within three miles of shore.

Maryland Boating Education Requirements

Who Needs a Boater Education Card?

Here’s the main rule. If you were born on or after July 1, 1972, you must have a Maryland Boater Education Card to operate any motorized vessel. That includes boats powered by gas, diesel, or electric motors.

The good news? Once you earn the card, it’s good for life. You never have to renew it.

Wondering how to get one? You can take an in-person course through the Maryland Natural Resources Police or U.S. Coast Guard Auxiliary. You can also take an approved online course. Or you can pass an equivalency exam if you have boating experience.

What About Young Boaters?

Anyone under 16 years old cannot operate a motorized boat 11 feet or longer without supervision. A supervising adult must be at least 18 and must hold a valid boater education card.

For motors on boats shorter than 11 feet, a person of any age with a valid card can supervise. Still, safety first.

You must carry your Boater Education Card on the vessel whenever you operate. Not having it with you can result in a fine, even if you completed the course.

Boat Registration in Maryland

Every motorized vessel used on Maryland waters must be registered with the Maryland DNR. This applies to boats powered by gas, diesel, or electric motors.

Here’s a recent update. In April 2025, Maryland raised boat registration fees for the first time in 42 years. Starting October 1, 2025, the fee went from $24 every two years to $70 every two years. It’s still a small price compared to the fines for not registering.

Once registered, you get a registration card. Keep it on board at all times. Officers can ask to see it.

Out-of-state boats can use Maryland waters for up to 90 days without registering here. Visiting boaters from other states can boat for up to 60 days if they are at least 16 years old or hold a NASBLA-approved boating certificate.

Some vessels are exempt from registration. These include U.S. Coast Guard documented vessels, non-motorized vessels that are not numbered, and boats used solely for racing that hold a valid racing number.

Important: If you sell, destroy, or transfer your boat, notify the Maryland DNR within 15 days.

Life Jacket Laws in Maryland

Okay, this one’s important. Life jackets save lives. Maryland law requires you to have one for every single person on board.

Basic Life Jacket Requirements

Every vessel, motorized or not, must carry at least one U.S. Coast Guard-approved wearable life jacket (PFD) for each person on board. The jacket must be the right size for the wearer and in good condition.

Boats 16 feet or longer must also carry one Type IV throwable PFD. That’s a ring buoy or seat cushion you can throw to someone in the water. Canoes and kayaks are exempt from the throwable requirement.

Life Jackets for Kids

Children under 13 must actually wear a life jacket, not just have one nearby. This rule applies on any recreational vessel under 21 feet while the boat is underway.

The jacket must be U.S. Coast Guard-approved and properly fitted. A loose life jacket can slip off in an emergency.

Life Jackets on Personal Watercraft

If you’re on a jet ski or any personal watercraft (PWC), everyone on board must wear a life jacket at all times. This includes the operator and all passengers. No exceptions.

Anyone being towed behind a boat on water skis, a wakeboard, or a tube must also wear a life jacket at all times.

Speed Rules and Navigation Laws

There’s no single statewide speed limit for boats in Maryland. But there are important rules about how fast you can go in certain situations.

The 6-Knot Rule

You must slow down to 6 knots (about 6.9 mph) or slower when within 100 feet of another boat, a pier, pilings, a bridge structure, the shore, or people in the water.

Think of it like a school zone for boats. Slow down when you’re near people or structures.

Other Navigation Rules

You cannot operate a boat in water less than 18 inches deep unless you’re crossing or overtaking.

Stay at least 300 feet away from anyone swimming or fishing. That gives them space and keeps everyone safe.

Navigation lights must be on from sunset to sunrise. If you’re out after dark, make sure your lights work.

Boating Under the Influence (BUI) Laws

Here’s where things get very serious. Drunk boating is illegal in Maryland. Full stop. The same rules that apply to driving a car apply on the water.

The Legal Limit

The legal blood alcohol content (BAC) limit is 0.08% or higher. If you’re at or above that level, you’re legally under the influence. You can be arrested on the spot.

But here’s the thing. Even if you’re below 0.08%, you can still be charged if officers believe your ability to operate is impaired. Alcohol, drugs, and prescription medications all count.

The Penalties for BUI

A first BUI conviction can land you up to one year in jail. You can also face fines up to $1,000.

Second offense? Those penalties double. Third offense? They triple. Repeated BUI convictions can lead to up to five years in prison and fines up to $10,000.

There’s also a lesser charge called “operating while impaired.” If convicted of impairment (below full BUI), you could still face up to 2 months in jail for a first offense.

Nick’s Law: A 2024 Update

Maryland got stricter in 2024. “Nick’s Law” went into effect on July 1, 2024. The law is named after Nick Barton, a 21-year-old college student who was killed in a boating crash on the West River in 2022.

Under Nick’s Law, courts can now ban a BUI offender from operating any vessel in Maryland for up to two years. If the BUI incident resulted in a death, the ban can last up to five years.

Before this law, the maximum ban was only one year, or two years for fatal incidents. This is a major change. Honestly, it’s a law that makes sense.

Officers take BUI enforcement seriously. During the Fourth of July weekend in 2024, Maryland Natural Resources Police made nine BUI arrests, the highest number in six years during that enforcement period.

Personal Watercraft (Jet Ski) Rules

Jet skis and other personal watercraft are super fun. But they come with extra rules in Maryland.

You must be at least 16 years old to operate a PWC. Even if you have a boater education card, the age minimum still applies.

PWC operators born on or after July 1, 1972 must carry a valid boater education card. All PWC must display regulation stickers from the Natural Resources Police explaining operating rules.

PWC must also be equipped with a kill switch or a self-circling device. That’s a safety feature that stops or steers the craft if you fall off.

Water Skiing, Tubing, and Towing Rules

Towing people behind a boat is a blast. But there are rules.

When you’re towing someone on water skis, a wakeboard, or a tube, the boat must have at least two people on board. There needs to be an operator and an observer who is at least 12 years old.

The observer watches the person being towed and signals the driver. One person cannot do both jobs safely.

Water skiing and towing are not allowed from sunset to sunrise. Stay off the water at night for this activity.

You cannot tow anyone within 100 feet of bridge pilings, docks, shore, other boats, or people in the water.

Anyone being towed must wear a life jacket. No exceptions.

Boating Accident Reporting Rules

If you’re in a boating accident, you have legal duties. This part can trip people up.

You must stop your vessel immediately after an accident. You must give assistance to anyone who is injured or in danger, unless doing so would seriously endanger your own boat or passengers.

You must provide your name, address, and vessel information to anyone injured and to the owner of any damaged property.

Most importantly, you must file a written report with the Maryland DNR within 48 hours if the accident results in a death, disappearance, injury requiring more than first aid, or property damage over a certain amount.

Failing to report a serious accident is a violation of Maryland law.

Common Violations and Penalties

Let’s talk about what happens if you break these rules. It’s not fun.

If you’re convicted of two violations within one year related to vessel operation or required safety equipment, you must take and pass a boating safety education course, regardless of your age.

Anyone convicted of careless or negligent boat operation must also take a safety course.

BUI convictions can mean jail time, fines, and now a boating ban under Nick’s Law. Those penalties stack up fast.

Think of most violations like a traffic ticket, but on the water. Some are minor fines. Others, like BUI, are criminal charges with serious consequences.

How to Stay Legal on Maryland Waters

You don’t need to memorize every law. But you do need to know the basics before you hit the water.

Here’s your quick checklist. Make sure you have your boater education card if you were born after July 1, 1972. Confirm your boat is registered and the card is on board. Check that you have a life jacket for every person. Bring a Type IV throwable PFD if your boat is 16 feet or longer. Make sure kids under 13 are wearing a life jacket.

Do not drink and boat. Assign a sober operator every time. And if you’re going to tow someone, make sure you have a second person in the boat to observe.

Trust me, following these rules is much easier than dealing with fines, arrests, or worse.
