A person can use a human-powered vessel within the marked channels of the Florida Intracoastal Waterway (ICW) under these conditions:
- When the marked channel is the only safe option due to vessel congestion or obstacles in the water. In this case, the person must leave the ICW as soon as possible.
- When crossing the channel is done directly and quickly without disrupting other vessel traffic.
- Only during a life-threatening emergency.
