CoastMate
Coming soon to iPhone and Android

Plan a safer day on the water.
Just ask.

CoastMate is a voice-first app for recreational boaters. Talk to it hands-free to build a float plan, check conditions, and keep your shore contacts in the loop.

Get in touch

Built for the helm

Hands wet, hands busy, eyes on the water. CoastMate is designed to be used by voice.

Float plans

Describe your trip once. If you are overdue, CoastMate escalates alerts to the shore contacts you choose.

Anchor watch

Set your anchor position and get an alarm if your boat appears to drift outside the radius you set.

Tide alarm

Depth-aware alerts built on NOAA tide predictions, so you are not surprised by a falling tide.

Backup navigation

A simple compass and position view as a fallback alongside your primary navigation.

Ask anything

Ask questions about weather, preparation and boating basics and get plain-language answers by voice.

Trip log and photos

Keep a record of your outings, with photos, on your own account.

Important: CoastMate is an informational and planning aid. It is not a substitute for official charts, marine radio, weather services, or sound judgment, and it does not provide advice about alcohol or impairment. The person in command is always responsible for the vessel and everyone aboard.
