The rule amendment modifies seven zones in the Florida Intracoastal Waterway on the St. Johns River in a manner which maintains the existing footprint of each zone as currently marked. The amendment modifies the locations used to describe zone boundaries, increases the regulated vessel speed in the year-round zones from “Idle Speed No Wake” to “Slow Speed Minimum Wake,” repeals duplicative regulations in two tributaries, updates rule maps, removes the authority for Lake, Seminole and Volusia counties to mark the state-adopted year-round boating restricted areas and includes language to exclude water bodies such as canals and boat basins.
