Oar Length

So I am running a 16' cat with a 72" wide frame and I am looking to buy new oars. I currently have 9-1/2 foot long oars but I don't feel like they're giving me what I need. I usually run Shoshone on down, the Roaring Fork, Westwater, the Upper C and Moab Daily type runs. So what are the buzzard's advice on oar length? I have the manufacturer and type picked so I wont get oar envy but what length do you think would work with my rig

I know that there have been many threads on this topic. If you search for oar length you will most likely find your answer. But it winter time so I am sure we can all re-hash the topic again. Good luck with your purchase.

I row 10's on a similar setup... I kind of wish they were a 1/2 foot longer.

I am running a 18 foot Aire cat and am happy with 11 foot cataract oars.

tried 10 footers but the 11 footers felt better.

friend of mine with 16 foot cat went with 11 footers for his GC trip.

Most likely oar length happyness is as much oar setup details and height of seat etc etc.

get 10 footers and one foot alunimum extenders for each oar. for big white water days use the ten footers (quicker movement, easier placement, less oar to get in the wrong spot at the wrong time), for long flat water days toss on the extenders and get more purchase for your efforts.

remember the golden rule of oar length...

1/3 inside the oarlock and 2/3 outside the oarlock (including blade). this gives you the most power.

so based on your frame width and preferences as to how far apart you like your handles when rowing - figure out how much 1/3 needs to be then multiple that by 3 to get your oar length.

also remember when you buy a 9ft shaft it is about 7ft long to account for the 2ft or so of blade.

happy rowing.

I don't support the notion of buying shorter oars and getting extenders. I added extenders to my first setup, which had too short of oars. They are extremely heavy (2' total aluminum length), clunky, and switching back and forth between 1' difference is a heck of a lot. Perhaps if they came out with 6" extenders, but they'd still be heavy beasts out at the end of your shaft.

I use 10's on a 14' raft, and generally like longer oars. I also sit on the cooler which puts me higher which pushes me towards longer oars for properly reaching the water. I keep the handles close together and my towers are on the outer rail of a double-rail frame, which makes it more manageable to have longer oars.

Keep in mind you can cut oars shorter, but can't lengthen them. That's a bit of a hassle, but I erred on the side of longer oars when I bought our latest raft, risking that I knew I could always cut them off. I never did do that, and stayed with the 10' length.

I believe this is bassackwards in most instances. It depends on the angle of your oars relative to the surface of the water. Most people row with oars at far less than 45 degrees from the surface. In this instance, if you maintain the same oar position relative to your body and raise your seat, the oars would be shorter to reach the water.

Are you serious? You move your lever further from the water and you need shorter oars? I don't agree.

In order to maintain submersion in water, raising your seat/towers would cause your submerged oars to be more vertical and closer to the boat, which takes power away and I don't like. It also is difficult in shallow water.

Raising the seat would actually shorten the oar length required (as Wade mentioned)....scientifically speaking

however i also agree with ihowemt that it would feel akward with shorter oars.
