the original post listed In Rhode Island: Wickford Marine consignment: Marine Consignment of Wickford, RI
The owner's name is Sam. He let me take some photos in the shop last winter.
These pictures don't do the place justice. You literally have to wade through the gear. Shopping there is an adventure. They post some of their inventory online and will ship just about anywhere. I've found many bargains there. They also have a store in Mystic, CT.
Also Newport Nautical Supply newportnautical Home Page
has a consignment section, but their consignment webpage is currently offline.
