Abstract: A connector for a assembling members of a floating dock system comprises at least one post and a brace extending from the post. The post is shaped generally complimentarily to the shape of the socket, and comprises a generally convex midsection connected between a pair of generally falcate end portions. The post and brace define a flat, generally horizontal top surface to the connector. The dock system also includes a supplemental floatation system having a hollow floatation member body defining a chamber. The body includes a water port positioned to place the body interior in communication with water. An air port positioned vertically above the water port is placed in communication with a pump. A valve can be positioned between the chamber and the pump to selectively place the chamber in communication with the pump or to place the chamber in communication with the atmosphere.
