Boating and paddling in Michigan, explained

Current for the 2026 season. Rules change — confirm at Michigan.gov/Boating before you launch. See what changed this year.

The short version

No state is built around water like Michigan. Four Great Lakes, 11,000 inland lakes, tens of thousands of river miles, and more freshwater coastline than any state in the country. We’re a top-three boating state by registrations — roughly 800,000 boats — and that’s before you count the kayaks. Almost every rule on the water hangs on one question:

Does your boat have a motor?

• Motor — any motor, even a little electric trolling motor: you’re in the regulated world. Registration with the Secretary of State, possibly a boating safety certificate, equipment requirements.
• No motor: canoes, kayaks, and paddleboards need no registration and no certificate — just life jackets and judgment. (Hand-powered boats over 16 feet, like big rowboats, are the one exception that registers.)

That trolling-motor trapdoor catches thousands of kayak anglers a year. Clamp one on and you’ve switched tracks entirely.

The certificate: the two-birthday law

Michigan has no “boating license.” It has a one-time boating safety certificate that never expires. Who needs it depends on what you’re driving and when you were born:

You’re operating…	You need the certificate if you were born…
A motorboat over 6 hp	on or after July 1, 1996
A personal watercraft (jet ski)	after December 31, 1978
Anything 6 hp or less, or a paddle craft	Never required (but always smart)

Yes, the two cutoffs are different — that’s the law, not a typo. A 45-year-old can legally captain a 300-horsepower cruiser with no course, but needs the certificate to ride a Sea-Doo. And the PWC hard floor: no one under 14 operates a jet ski, ever. Riders 14–15 need the certificate plus a parent or guardian (or their designated adult, 21+) aboard or within 100 feet. The full youth chart is on the certificate page.

Registration, in one paragraph

It runs through the Secretary of State, not the DNR — the most common wrong-door trip in Michigan boating. Register every motorized watercraft (no horsepower minimum), all sailboats, and hand-powered boats over 16 feet. Canoes, kayaks, and paddleboards are exempt. Three-year cycle expiring March 31; fees scale with length; titles at 20 feet or a permanent engine. The full decision table is on the registration page — including the heads-up that a bill to raise fees about 30% was pending in the Legislature as of mid-2026.

Life jackets, in four sentences

Every boat — kayaks and paddleboards included — needs a Coast-Guard-approved jacket per person, accessible, not buried under the cooler. Children under 6 wear theirs on any open deck underway — the most-enforced rule on the water. Everyone on a PWC or being towed wears one (non-inflatable). Boats 16 feet and up add a throwable. The full rules and the porch sermon are one click away. The sermon is short: cold water steals your swimming ability in minutes, and most of the people Michigan loses each year would have lived in a jacket.

The laws of the lake (the short list)

• Slow-no-wake within 100 feet of docks, rafts, anchored boats, and shore. Many lakes add their own ordinances — night no-wake hours, ski zones, PWC limits. Check your lake, the same habit our fishing guide teaches for limits.
• PWCs: off the water from sunset to 8 a.m.; kill-switch lanyard attached; 150-foot spacing rules.
• Towing sports: observer aboard (or wide-angle mirror), jacket on the towed person, done an hour after sunset.
• Drinking: boating under the influence is 0.08 BAC, with drunk-driving-grade consequences. Sun, wind, and waves multiply alcohol — one beer on the water hits like three.
• Kill switch: federal law requires the engine cut-off lanyard on planing boats under 26 feet.
• Clean, Drain, Dry — it’s the law, same as for anglers. Pull plugs, drain wells, remove plants at every launch.

The page that matters most

Lake Michigan is, statistically, the most dangerous lake in America — roughly half of all Great Lakes drownings. The flag system, the pier rules, and the Flip, Float, Follow survival method fit on a postcard. They’re the most important thing on this site for a family headed to the beach: Great Lakes beach and water safety.
