On the lever C and projecting over the boat, and adapted is a base, or seating H, which is adapted to to swivel thereon, and a rowing handle, and rotate simultaneously with the wheel D, to an oar, connected therewith. gether with the concentric pin 8. The seat 70 The objects of my invention are, first, to ing H, and the wheel D, operate together provide means on a rowboat which will row as one, and both are secured to, and rigid the boat in an opposite direction to the di with the pin S. The pin 8 operates loosely lection of the rowing handle and oar, that is, in the forks of the lever C. The inner end in the direction facing the rower, second part of the lever C, has a suitable horizontal 75 to provide means whereby the rower may Socket to allow the insertion of the tapered easily dip the oal more or less in the Water outer end part of the rowing handle J, which at pleasure, third, to provide means whereby is adapted to fit Snugly in said Socket, and the lower may raise the oar completely out to be withdrawn therefrom.
