The Adventures in Boating Washington Handbook provides a checklist of legally required items by boat type and size. The following is a short list of key equipment you should carry on board.
The required navigation lights must be displayed between sunset and sunrise and during periods of restricted visibility such as fog or heavy rain. See requirements for larger vessels by visiting the U.S. Coast Guard’s online navigation rules.
Properly installed ventilation systems greatly reduce the chances of life-threatening explosions. Find out about ventilation requirements for various gasoline-powered vessels. A gasoline-powered motorboat (not outboard) requires a backfire flame arrestor as well. Mufflers are required for all vessels, except canoes and kayaks.
All boaters, including those using canoes, kayaks, and personal watercraft, must carry a sound signal, such as a horn, bell, or whistle. Learn key sound signals to avoid confusion and or collisions. The device must be audible for a half-mile.
All boats, except canoes, kayaks, and personal watercraft, must display a sticker warning passengers about the dangers of carbon monoxide poisoning. Details and how to get your sticker.
