Ship Strikes

Predictive tools based on sea turtle sightings, including information on turtle behavior within particular habitats and seasonal variations, can help to reduce ship strikes.

Ship strikes occur when a boat makes contact with a turtle in the water. The severity of a ship strike corresponds to the size and speed of the boat. The impact can either kill the turtle instantly or will lead to a slow death from wounds, internal injuries, or impaired buoyancy.

Turtles are particularly vulnerable to boat strikes when they surface for air and when they are resting at the surface between dives. All species of sea turtles are at risk from ship strikes. However, sea turtle species known to spend more time near the surface face grater risks than their counterparts at depth.

Ship strikes in coastal areas are primarily caused by recreational craft. Transoceanic shipping vessels present risks to sea turtles migrating or foraging in pelagic habitats. Nearly one-tenth of stranded turtles show evidence of ship strikes, but it is likely that turtles struck by a boat, far from shore, never wash up.
