If your still looking for help with times out to open water in Cape Coral, Please call me. I am an avid boater and have sold homes in all areas of Cape Coral. I will be able to give you the info you need. Also something to think about are bridges and locks.
Kathi, Anyone working in the Cape should be able to approximate the times for you! I would be more than happy to help you! I live in unit 74 and at different times the trip varies but 45 minutes to the lock at idle speed is normal. Contact me if I can be of help!
Please let me know where you are looking at in the cape and I will find out the times for you. I am an avid boater so I have knowledge and know a few guys that work out of the marinas that could provide it if I don't know myself. I look forward speaking to you.
