ABSTRACT:
An apparatus for use in forward facing rowing of a boat having oars mounted ahead of the oarsman and having a seat fixedly secured in the boat is disclosed. The apparatus comprises an inboard support assembly and an outboard support assembly. The outboard support assembly is connected to boat oars for pivotal movement of the oars with respect to the outboard support assembly in at least horizontal and vertical planes, and also allows rotational movement of the oars with respect to the outboard support assembly. The inboard support assembly is comprised of a mounting bracket slidably secured within the boat, as well as a first elongate support and a second elongate support, both of which are pivotally attached to the mounting bracket for horizontal movement of the first elongate support and the second elongate support. The outboard support assembly comprises an oar support pivotally connected to boat oars and to the first elongate support and to the second elongate support for horizontal movement of the oar support. The outboard support assembly also includes an oar brace pivotally connected to the second elongate support for at least horizontal and vertical movement of the oar brace. The oar brace is pivotally connected to boat oars for movement of boat oars with respect to the oar support in at least horizontal and vertical planes and for rotational movement of boat oars with respect to the oar brace.
