Iowa life jacket laws (and kids)
Children
Children under 13 must wear a USCG-approved wearable life jacket while underway on any Iowa waters, unless in an enclosed cabin or below deck, or a passenger on a commercial vessel that carries 25 or more people.

Everyone else, towing and seasonal rules
Anyone towed behind a vessel or PWC must wear a USCG-approved wearable life jacket. Boats 16 ft and longer (except canoes and kayaks) also need a throwable device. 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 “Iowa 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
Ages 12–17 operating a vessel with a motor over 10 hp (including a PWC) must have passed an Iowa DNR-approved boater education course, unless an experienced person 18 or older is on board. Under 12 may operate over 10 hp only with an experienced person 18+ on board. Adults are not required to take the course.

Minimum age
No fixed minimum: under 12 only with an experienced person 18+ on board; 12–17 need a boater education certificate or that same supervision

Everyone on board must wear a USCG-approved Type I, II, III or V life jacket (no inflatables); no riding between sunset and sunrise; lanyard must be attached whenever the engine runs; no more than 10 mph within 300 ft of shore on inland lakes and federal impoundments; no more than 5 mph within 100 ft of a vessel going 5 mph or less, or within 50 ft of a faster vessel; no chasing wildlife.

Kayak, canoe, paddle board and kite rules
Canoes, kayaks and SUPs over 13 ft, or any with a motor or sail, must be registered. SUPs are vessels and need a life jacket for each person, a whistle and visual distress signals on federally controlled waters, and a white light (a flashlight or headlamp is enough) from sunset to sunrise. The handbook has no specific rules for kiteboarding.
Boat registration in Iowa
Every vessel on public waters must be registered (3-year registration through the County Recorder), except non-canoe/kayak inflatables 7 ft or shorter; canoes, kayaks and SUPs (including inflatables) 13 ft or shorter with no motor or sail; and boats registered in another state that use Iowa waters 60 days or less per year. Inflatables, kayaks and canoes are exempt from titling.

VesselSOS on Iowa 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.
- 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.
