I'm trying to wrap my mind around oar length to tower ratio too. The way I understand, or maybe kind of understand is that the width between the pivot points (oar lock/tower dimension) determine the length of the oars? Looking at Raft Frame, Cataraft, Cataraft frame, Whitewater Stern Frames
drawings this seems to be the case.
I have a 10.5 raft, the oar towers recommended are 8 inches out and 12 inches up. The drawings indicate either an 8 or 8.5 oar to balance out with out extra weights. This seems to be longer oars than what my research on the internet has found for my length of raft.
Does oar length relative to width of towers and length of boat collide with practicality? Are we overthnking this?
Are 8 to 8.5 foot oars suitable for a10.5 raft ? Is that to much leverage? Or is the balanced/weight neutral oar (without extra weight)the holy grail. More leverage is it better? Is it geometry + or - a little bit.
Where does boat length come in to this?????????
Dear Abbey, please help.........confused.
