A superb description of Tween Waters Inn and Marina from Captain Gary. Could not have done a better job myself!
Tween Waters is accessed via a marked channel from the Western Florida ICW, making into the eastern shores of Captiva Island (south of South Seas Plantation).
Tween Waters Inn and Marina is a good cruising destination but one must be prepared for a different docking situation. They have a long face dock for side-to docking for larger boats.
Smaller boats will be docked closer to shore in slips. These slips have no finger piers so one must exit their boat via the swim platform. With low tides this can be difficult, so be sure to carry a small step ladder that will fit your swim platform. Also, you will take a spring line off the piling to tie either amidships or bow, depending on the length of the boat. This line is attached to the piling by a pulley with a weight on the end. This keeps tension on the line and really does keep the boat in the proper spot.
There are two restaurants on the premises that allow for casual or upscale dining. The Old captive House has many local fish favorites on their menu plus items for the landlubber. The weather was quite chilly when we were recently there and the fireplace in the Crow’s Nest was wonderful. Next door to the resort is the Captiva Island Yacht Club for those who have reciprocal privileges.
The beach is just across the street and they have a large heated pool and spa. All in all, this is a good destination or a stop on a longer cruise.
