If someone is stuck in the mudflats
- Call 911 immediately. Do not walk out to them.
- Keep the person calm; have them lean back to distribute weight.
- Do not let them yank the trapped limb — it sets the suction harder.
- Note GPS coordinates if possible. Direct responders to the nearest highway pullout.
- Mark their position from shore (a fixed visual reference) so responders can locate them.
If a surfer fails to return when expected
- Call 911 and report the launch and expected exit locations.
- Provide vehicle description and last-known position.
- Do not enter the water to search.
If you are in trouble in the water
- Stay with your board. It is the most visible thing on the water.
- Conserve heat. Get knees to chest if possible.
- Signal shore: arm waves, whistle, light.
