Riggers are used with rowing or sculling boats to provide pivot points for oars. The invention provides an alternative rigger 30 to those typically known in that it comprises two arms 40 and 50 each including a pivoting means 42 and 52 for pivoting each arm between an extended position and a retracted position relative to a boat 10. The rigger also includes locking means for adjustably locking each arm in any desired position at, and between, the extended and retracted positions. The locking means may comprise a clamping means using interlocking teeth (143 and 145, Fig 6) or means for squeezing a ball (345, Fig 8) and socket (343, Fig 8) together to restrict movement therebetween. A boat provided with the rigger is also disclosed. |
