Abstract

PURPOSE:To vary the size of a sail freely by constituting a sail supporting boom with two flexible-in-length pipe members. CONSTITUTION:A boom 5 that is attached to a mast 4 is made up of two pipes 8. These pipes 8 are made up of two pipe members 9 and 10 which can be fixed by a fixing unit 11 and moreover are flexible in length. To adjust the length of the boom 5, seal elements 21 and 23 are attached to the pipe member 10, inserted into the pipe member 9, and a tightening cap 14 is tightened to an outside screw thread 12, keeping the pipe member 10 in the desired position. With this operation, an insert piece 16 is connected to an end of the pipe member 9 in form of a wedge so that the both pipe members 9 and 10 are fixed in the desired position.
