Boating accidents jumped both statewide and in the Florida Keys in 2011, reports the Miami Herald.
Monroe County held the top position of the most dangerous county for boating, with six boating deaths and 66 injuries in 2011.
That fatality toll includes the three powerboat racers killed in two crashes during a Key West race in November. Two fishermen were killed in August when a flats boat crashed into a utility pole at the Cards Sound Bridge.
Overall, Florida marine officers statewide reported 742 accidents and 67 deaths. Of the 742 accidents involving 1018 vessels, boats hit other boats or stationery objects in 313 cases.
The most common fatal boating accident was falling overboard. In two-thirds of the fatalities, drowning was ruled as the cause of death.
Careless operation was the most common reason for accidents. Next were mechanical failure, operation inattention, operator inexperience, bad weather, and speeding.
There were 308 arrests statewide for boating under the influence last year, and ten boating deaths in 2011 were linked to alcohol.
With 75 maritime mishaps, Miami Dade County was the second most dangerous county for boating.
Other counties with high accident numbers were Palm Beach (58), Broward (41), Lee (41), Pinellas (36) and Collier (34).
