Between the Keys and Fort Meyers I think you might have some problems with your
draft if you wished to pull in someplace such as the Shark River, but the trip to Fort Meyers is relatively short. From Ft Meyers north to Tampa Bay and even to Tarpon Springs, things look up a bit for you but I'd say Tarpon is about as far north as you're going to get without heading
offshore. If you try to get into Naples you will probably find portions too shallow for you on the river. Bridge height shouldn't be an issue because they will either open or if fixed, I believe their clearance is 65 ft. Be wary of the
ICW because portions have shoaled. Entry into places such as
Sarasota is probably out of the picture because of shoaling. I draw 5 ft and wouldn't attempt it except by using the
ICW from Tampa Bay.
You will have to watch the tides and your
depth finder. Even in Tarpon Springs, which is where I'm based, you will find the river deep enough, particularly at high tide but the
offshore area around Anclote Key can have some rapid
depth changes and is only around 10 ft to begin with. It can be done but go slow. Your draft is not too common around these
parts, most are 5 ft or less.
