Abstract
An improved oarlock system having a sleeve that is attached to an oar, a set of cam blocks installed in the sleeve that can be moved to adjust the inboard of an oar, an oarlock that is positioned over the sleeve so that it contacts the cam blocks. There are several combinations of sleeve type and cam block available for use. The oarlock can be fitted to different sized pins. Pitch of the oar can be easily adjusted using the oarlock and sleeves. Improvements in the use of the sleeves, cam blocks and oarlock permit replacement of worn parts and increased stability of the components when in use as well.

An oarlock system for use on an oar having a shaft comprising:
- a) a sleeve, removably attached directly to the surface of said shaft of said oar, said sleeve having an adjustment channel, having a length formed therein, said adjustment channel being in alignment with the longitudinal axis of said oar such that the length of the adjustment channel is parallel to the shaft of said oar;
- b) a cam block, adjustably attached to said sleeve and having a cam portion extending outwardly therefrom, said cam portion fitting into said adjustment channel to permit positioning of said cam portion along the length of said adjustment channel;
- c) a means for temporarily fixing said cam block in a position on said sleeve;
- d) an oar retainer including:
- i) two semicircular members designated as the oarlock lock side half, and the pin side half, said two semicircular members being hingably connected;
- ii) a latch, attached to said two semicircular members to temporarily lock said two semicircular members together;
- and further wherein
- iii) said oar retainer being positioned perpendicularly to the length of said adjustment channel;
- e) a means for engaging said cam block, formed within said oar retainer;
- and
- f) a means for attaching said oar retainer to a watercraft;
