ABSTRACT:
A new and improved leg assisted forward rowing system wherein a user can mechanically advantage the rowing of a boat by first pushing his foot forward along a foot glide member which is slidably engaged within a first track member. This force is transferred to the oar via a pulley belt system that engages both the foot sliding mechanism and an oar movement mechanism. The oar movement mechanism comprises an oar glide member that is forced by the pulley belt system to slide within a second track member in the opposite direction of the foot sliding mechanism. Attached to the oar glide member is an oar support mechanism in which the handle of an oar is received within an oar lock having a downwardly extending stem. The oar lock stem is slidably received by a stem support member that allows the stem to slide upward and downward therein. Additionally, the oar lock is dimensioned to allow movement of the oar handle; however, this movement may be controlled/restricted by the insertion of filler material (i.e., rubber, foam) within the oar lock. Moreover, the stem support member is attached to a triangular support member that is hinged to oar glide member. Thus, the freedom of movement of the oar creates a natural feel to the user, yet his rowing efforts are advantaged and more efficient. A mirror image arrangement is carried by the other side of the boat for receiving the user's other foot and thus advantaging his rowing efforts for the other oar.
