The main Wrightsville Beach Anchorage is to port as you head south through the bascule bridge. Green marker "29" is the first of a series of channel markers to lead you to the Motts Channel. (This is the one we missed as it had fallen off the pole.)
Follow the channel until red marker "16". Avoid the shoal as you turn to port, then anchor between the channel and the fixed bridge. The bottom is sand and good holding. The tide is about 2 ft. You can come ashore on the public property near the bridge or get permission to beach your dinghy further south of the bridge. One of the churches owns part of the waterfront property. Laundry and groceries are a within a short walk.
Equipment: We came in lower down on Shim's Creek, which is a deeper channel and not so subject to shoaling as the Mott Channel. See chart (photo 2)
Where we anchored is more isolated - if you want to go ashore (we didn't) it will be a longer dinghy ride.
Wrightsville Beach is hospitable to boaters and will allow you to stay anchored for several weeks. Just be sure to stay out of the channels, as they are patrolled.
Atlantic Marine is one of the largest dealers of Regulator, Edgewater, and Pathfinder boats and they also have used boats as well as storage. This is not a place that we would be interested it - primarily small motor boats. So I cannot speak to the quality of their work and I'm not absolutely sure that this is a picture of Atlantic Marine.
They can rebuild outboards with technicians trained and certified to work on Mercury, Yamaha, and Johnson outboards.
They will also do full detailing and repair as well as installation of electronics packages, T-Tops, and other custom work and in the fall will winterize your boat..
The Wrightsville Yacht Club seems to be fairly secretive - they have a website (below) but you have to be authorized to enter it.
The Wrightsville Beach Marina on the other hand is on the eastern shore of the ICW, just south of the Wrightsville Beach drawbridge, they have power, water, telephone service, cable TV and Internet connections, fuel and mechanical repairs, and a swimming for transients. It is right next to the Wrightsville Yacht Club
