Abstract: A holder for the shaft or pole of a signal pole used in boats to indicate that an occupant of the craft, or a water skier being towed by the craft, is in the water. The holder is comprised of a pair of relatively rotatable disk-like members, the first of which is attached to the boat, and the other of which is rotatably secured thereto. The second member receives a flag pole or shaft and as the member rotates the shaft is moved between a vertical operative position and a horizontal inoperative position. Automatic stop means control the rotation so as to readily position the shaft in said two positions.
