West Indian manatees suffer thousands of boat strikes annually, causing serious injuries and deaths in Florida and Caribbean waters.
Boat strike injuries are among the most painful and preventable harms to manatees. Propeller wounds penetrate deep tissue and bone, causing prolonged suffering. Even non-fatal strikes cause chronic injuries affecting mobility and feeding ability. Slow-speed zones, when enforced, significantly reduce strike rates and represent one of the most direct welfare interventions available.
