Emergency on the water in Wisconsin
Emergency and non-emergency contacts in Wisconsin
Call 911 for emergencies on all waters; on Lake Michigan and Lake Superior you can also call the U.S. Coast Guard on VHF Channel 16. The DNR violation hotline, 1-800-TIP-WDNR (1-800-847-9367; call or text, 24 hours, confidential), is for reporting natural resource violations. The DNR says it is not an information number, and it is not for emergencies.
Coast Guard sectors covering Wisconsin
Each sector runs a 24-hour command center. Its line is useful for reporting an overdue boat or reaching the Coast Guard by phone, but in a distress use VHF Channel 16 or call 911 first.

| Sector Northern Great Lakes | (906) 635-3319 24-hour Coast Guard sector line · checked Oct 2026 · atlanticarea.uscg.mil |

Wisconsin life jacket laws (and kids)
Children
No state rule requires children to wear a life jacket. The handbook cites the federal rule: children under 13 must wear a USCG-approved life jacket while underway in an open vessel on federally controlled waters, and the state strongly recommends it on state waters.

Everyone else, towing and seasonal rules
All vessels, including canoes, kayaks and paddleboards, must carry a wearable USCG-approved life jacket for each person. Sailboarders and windsurfers do not have to carry life jackets (but are encouraged to wear one). There is no seasonal or cold-water rule.
The federal baseline
Federal default: children under 13 must wear a USCG-approved life jacket on a recreational vessel that is underway, unless they’re below decks or in an enclosed cabin. Where a state has its own child-wear rule, the state rule applies on its waters (33 CFR 175.15(c), 175.25). Coast Guard required safety equipment →
Boater education card (the “Wisconsin boating license”)
Most states don’t issue a boating license. What they require is a boater education card: proof you passed an approved boating safety course.
Who needs it
Anyone born on or after January 1, 1989, operating a motorboat (including a PWC). For motorboats other than PWC, ages 10–15 may instead be accompanied by a parent, guardian or designated adult who is certified or born before 1989. Ages 16 and up must have the course or be accompanied by a certified (or pre-1989) person who is at least 18. On a PWC, the course is required for anyone born on or after January 1, 1989, and supervision does not replace it. Under 10 may not operate a motorboat.

Minimum age
12 (ages 12–15 must have completed a DNR-accepted boating safety course; under 16 cannot rent or lease a PWC)
Rules on the water
Everyone on board must wear a USCG-approved life jacket; lanyard must be attached to the operator; no riding between sunset and sunrise; always face forward; slow, no-wake speed within 100 ft of any other vessel, within 100 ft of a dock, pier, raft or restricted area on a lake, and within 200 ft of shore on any lake; no wake-jumping within 100 ft of another boat; no chasing wildlife.

Kayak, canoe, paddle board and kite rules
SUPs are vessels. Each one needs a life jacket for each person, a whistle on federally controlled waters, a white light (a flashlight or headlamp is enough) from sunset to sunrise, and visual distress signals on federally controlled waters. Sailboards do not need to be registered and are exempt from life jacket rules. The handbook has no specific rules for kiteboarding.
Boat registration in Wisconsin
Every recreational vessel must be registered (registration lasts 3 years), except sailboats 12 ft or shorter without a motor, sailboards, manually propelled vessels with no motor or sail, and boats registered in another state that use Wisconsin waters for less than 60 days in a row.

VesselSOS on Wisconsin waters
- Life in danger? One tap dials 911. The screen shows your GPS position and a word-for-word script: say “Boat emergency, I’m on the water” and the name of the lake, river or bay you’re on.
- On the coast and the Great Lakes it also shows which Coast Guard sector covers your position, with that sector’s 24-hour line as a second Call button, and a VHF Channel 16 MAYDAY script filled with your boat’s details for you to read on your own radio.
- A live link for family ashore (Plus, free during the beta): your position, speed, course and phone battery in any browser, no app needed on their end. You send it by text yourself.
- Not an emergency? The tow screen has Call buttons for the TowBoatUS and Sea Tow 24-hour dispatch lines, or your own member number.
What it doesn’t do: it doesn’t call the Coast Guard for you and isn’t connected to 911 or any rescue system. Nobody is alerted automatically if you’re late. The return-time check only asks “Are you OK?” on your own phone. It doesn’t replace a VHF radio, a PLB or EPIRB, or the life jackets the law requires.
iPhone only, in invite-only TestFlight beta. Not in the App Store yet, no Android. US support (911 routing, American English) is in beta version 1.4 and later.
