Abstract
Abstract A back belt for use by sailors particularly in racing to provide support when a sailor is inclined out from a side of the ship to counterbalance the inclination of the boat, the belt having portions to extend around crotch, waist, back and over the shoulders of the wearer, a front located hook device and an arrangement for an adjustable back support plate. The belt has a back portion that extends substantially the length of the back of a user and receives a supporting plate therein. The supporting plate is connected at its upper most end by adjustable straps that extend over the shoulders of a user and connect to a hook device in the front of a user. The bottom most portion of the supporting plate connects to an adjustable fork strap that extends under the crotch of a user and connects to a hook device on the front of a user. The supporting plate may be adjustably positioned relative to the back portion.
