The anchorage reviewed below by Captain Jones lies just off the southern tip of Sanibel Island, and south of Sanibel Island Marina, within sight of the Point Ybel lighthouse. Several years ago, we removed this potential anchor down spot from out “Western Florida Marina Directory.” Several local captains informed us that the holding ground was poor, and several vessels had drug anchor into the nearby Sanibel Island Causeway and Bridge.
Obviously, Captain Jones has not had this problem on these waters, but just be aware that others have!

For many years I have anchored overnight on a ‘sailboat’ as well as ‘power’ just off Sanibel Isl south of the causeway bridge on the [south] tip of Sanibel. You will find 13 to 20 feet of water, and it is very protected from the traditional SE or SW winds. I would not recommend it with winds out of the N or NE. The area to anchor is approximately half way between the entrance to ‘Grandma Dots’ and the lighthouse on the east point of the Island. On weekends you will experience some wave action during the day from boats of all sizes transiting the area.
