Click the chartlet below, which will open a Chart View page centered on this anchorage. Now, even though they are not noted on the chart, be aware that high-tension powerlines cross the southern reaches of Matecumbe Harbor. Captain Erwan can certainly anchor here if he likes, but, for me, I would be sleepless the entire night anchored on these waters in a sailcraft, worrying about dragging into these deadly obstructions.
I’m not [in agreement] with the “powercraft ONLY”. I have a 31ft sailboat and we spent one night in its beautiful anchorage. There is enough room and depth to stay away from the power lines. The bottom is hard mud which hold very well.
You can go ashore using the dinghy and the channel 2 passage, but not possible on the bay side because it’s a private marina.
