Minimum depth needed for a mooring.

My mooring at my new house on Shelter island NY is 6'7" (about 2m) at lowest tide of the year and the ground is mud. I wanted to know if that's deep enough to keep a swan 47 with its centerboard up, draft of 5'6". 

 

thanks

Dear Kevin

If you are sure there are no rocks or mooring weights on the sea bed, it is suggested you try this. Inspect the underside of the keel and the centerboard slot for possible effects, and report to the Forum.
Kind regards

Your situation depends on the mooring because you say you have 1ft clearance, so it would take a wave with at least 2ft amplitude during the lowest tide to cause a grounding.  That's probably never going to happen on a dockside mooring in a sheltered marina.  On the other hand, I would be concerned if you're mooring on a bouy in open water.
