Ham Radio for River Rafting: Multi-Raft Communication on the Water

Six Rafts, One River, Zero Cell Service

River rafting trips spread rafts across miles of water with canyon walls blocking cell signals entirely. Ham radio keeps the whole group connected — from the lead raft to the sweep boat. Here is the setup.

Why Radio on the River

• Rapid alerts: Lead raft warns the group: "Big drop coming at the next bend"
• Group spread: Rafts naturally separate — radio keeps everyone coordinated
• Emergency: A flipped raft needs fast response — call instantly on simplex
• Weather: NOAA alerts for flash floods — critical on remote rivers
