ABSTRACT:
A rowing boat 10 has a fixed seat 14 and a movable foot stretcher 16 slidably mounted in guides 15. A swinging outrigger arm 17 is provided to support an oar by means of row lock 22 at its outer end. The inner end of outrigger 17 is pivotally mounted on a vertical axis 21. A coupling link 24 connects the stretcher to the outrigger 17, whereby as the stretcher is moved fore-and-aft during rowing the outrigger 17 is pivoted about axis 21. The link 24 is connected to the outrigger 17 at a point which is adjustable, and is always inboard of the rowlock. In an alternative embodiment the outrigger 17 is provided with a lifting member 33 which assists in raising the blade of the oar.
