KILO
The Alaska boating app for weather, tides, and vessels
Kilo is a free, map-first companion for running boats in Alaska — from the Inside Passage and Prince William Sound to Kodiak and the Aleutians. Check conditions and see what's around you before you leave the dock.
Marine weather built for Alaska waters
Land, offshore, and coastal NWS zone forecasts in one tap — wind, seas, and small-craft advisories for the cold, fast-changing water Alaska is known for.
NOAA tides for every harbor
Tide predictions from the nearest station with highs, lows, and the hourly curve — essential where 20-foot swings and strong currents are routine.
Live vessels and float plans
See AIS traffic around you for free, then file a float plan that emails your contact your route, expected return, and Coast Guard District 17 search-and-rescue info.
