icw bridge heights?
Cocoa beach isn''t on the ICW, the closest you can get is taking the barge canal over to the port at Cape Canaveral.
The bridge at 528 is something like 36 feet, and a few miles south of that is 520, which is even lower at something around 25 feet. If you come up from the south, and you have a short mast, you can make it under Pinedas causeway bridge at something like 43 feet.
The Banana River (body of water you need to go through to get to CB) is extremely shallow, there are channels, but the depth prohibits sailboats with any substantial draft.
I''ve plied those waters constanty in my youth in a daysailor. There''s a reason it''s not considered a sailing haven. Even with a daysailor I was constantly pulling up the centerboard, as the bulk of the river is a foot or two deep.
