Manatee Boat Strike Prevention

Boat propeller strikes are the leading human-caused injury and death for Florida manatees, causing painful wounds and slow deaths.

Key Facts

Over 1,000 manatees live in Florida waters year-round
Propeller wounds account for over 25% of manatee deaths annually
Slow-speed zones reduce strike risk substantially but compliance is low
Manatees cannot hear high-frequency boat sounds that would warn them
Carcass scarring shows that virtually all adult manatees have been struck at least once

Welfare Considerations

Propeller strikes cause severe lacerations and internal injuries that result in prolonged suffering before death. Animals with non-fatal strikes carry lifelong scars and ongoing health complications. Boat speed restrictions and exclusion zones in warm-water aggregation sites are the most effective welfare interventions.

What You Can Do

Respect manatee protection zones and slow-speed areas
Watch for manatees surfacing when boating in Florida waters
Support expanded manatee sanctuary designation
Donate to manatee research and rescue organizations
Advocate for stronger enforcement of manatee protection zones
