OK, if you are working at Little Creek there are several marinas
, including the one we keep our boat at as a live aboard. Off the Little Creek inlet towards Pretty Lake there is Bay Point Marina, Taylors Landing, Little Creek Marina, they all have live aboards, but there is a maximum number they allow. There is also Cobbs Marina you could try.
Group cover most of these marinas, check out Vinings Marine Group
for the contact numbers. Also try the marinas on Willoughby Bay, Rebel Marina and Willoughby Harbor.
