How many nautical miles from Boathouse Cape Coral to this Boathouse location? and what marker on Okeechobee Waterway? How far east from the I75 bridge? I have looked many places for this info and cant find it?

2 1/2 to 3 miles east of 75 bridge.

It's on the west side if the hwy 31 bridge if that helps. Be adventurous, trim your sails, fill your tank and be sure you have plenty to keep your throat dry and enjoy a ride on the water and some really great food. I had the shrimp basket, wife had the Maui Maui sandwich. Reasonable prices. From Ft. Meyers it's on the right just before the hwy 31 bridge.

I don't know about any of the nautical numbers but I can say that it's pretty close to 3 miles by road from I 75

I have no clue. I would call the boathouse..Since it is new, not sure is on maps..altho the boat repair entity is not new
