Don’t go faster than the posted speed limits when you see these speed limit signs on the St. Johns River.

Idle Speed No Wake Signs

idle speed no wake zone

This sign means the area you’re approaching requires boats to move extremely slow and not create wakes that come from boat motors going too fast. So back off on that throttle and move slowly here. Basically, an Idle Speed No Wake sign means that you should not be accelerating at all to create any wake. Maintaining steerage and headway is key here until you coast out of the no wake zone.

Slow Speed, Minimum Wake Signs

Here, boaters can create small wakes. Code: You can go a bit faster than idle speed here but move cautiously.

Don’t go faster than just above idle speed when boating in areas with these signs.

Maximum 25 MPH and 35 MPH Speed Zone Signs

These are controlled areas. Bottom line: Don’t go faster than the posted speed limits in these areas. Translation: It’s the boat version of a school zone on the water here.

Vessel Exclusion Area Signs

This sign is marked with a vertical diamond shape with a cross in the center and indicates boats aren’t permitted here. Typically, these are posted to let boaters know it’s a swimming area. For the St. Johns River, these signs are posted to let boaters know where people are swimming in places like Silver Glen Springs and other crystal clear water spots created by natural springs.

Manatee Zone Signs

Manatee signs alert boaters to slow down in areas where the revered and endangered manatees congregate. The words “Manatee Zone” are typically placed above a Slow Speed, Minimum Wake sign to let boaters know to look out for the big lovable sea cows. Sometimes there are stand-alone signs warning boaters to watch for manatees.
