Oar Length documentation

    For canoes that were originally sold with oars and oar locks, is there any documentation describing the length of the oars that would have typically been sold with the canoe? In my case, I am specifically wondering about an 18-foot square-stern canoe with sponsons (http://wcha.org/forums/index.php?threads/old-town-with-sponsons-serial-number-7180-18.15860/) but I am also asking about documentation in general.

    I occasionally see sets of used Old Town or even Shaw and Tenney oars for sale on Craiglist. I'm sure that if I called Shaw and Tenney they could provide a recommendation, but I am wondering if there is any historical documentation.

    For those (few!) of you that don't hate sponsons and have rowed canoes that have them, what length oars have you found to be comfortable and effective? :)

    Thanks for any feedback you can provide!

    The Shaw and Tenney oar length formula at https://www.shawandtenney.com/how-size-your-oars is a good place to start. I have rowed a variety of canoes but don't recall the oar lengths in each case. The 1961 Old Town catalog suggested 6.5 foot long oars for the square end canoes with sponsons. More information like this is available from http://www.wcha.org/store/complete-old-town-canoe-company-catalog-collection if you want additional details. Let us know what you decide to get and how you like them. Thanks,

    Benson

    Shari,
    Use the Shaw and Tenney formula or call Steve at the factory.
    I’ve rowed Square sterns and can tell you that 6.5” would be too short.

    Dave you just broke my heart...I'm on week 4 waiting on my oars that I used Old Towns advice of 6.5' for my 15' square stern...

    Erik,
    I’m sure 6.5’s will get you to where you want to go. I liked the 7.5’s for my 1944 square end. They reached out over the sponsons better in my opinion
    To be certain, I would use the formula on the Shaw Tenney web page or call directly to find out what they suggest. They have been sizing and building oars for around 160 years. Lean on them for what you need.
    It may well be that 6.5 is the prescribed length.
    I’m sure if you find out differently, they would change the order.

    I'll call tomorrow and see if I can change order!

    I'm inclined to agree with you...I rowed my friends 18' square stern with sponsons one time (6.5' oars) and I do remember it being a bit awkward at first and thinking oars bit short; but dismissed it as Old Town knows best. To your point...you just adapt to shorter oars. Back up to the outboard motor in my case anyway...

    Dave Osborn I owe you a big thank you. Measured and used Shaw and Tenney method and came up with 7' oars (15' square stern is a little narrower than 18'). Shaw is making 7' oars instead of 6.5 that old town had as universal recommendation.

    Glad it worked out for you, Erik!

    Dave I wish I had the 18'...But am lucky to have a 15' so I'll just count my blessings. Yours looks like it belongs in a museum not a driveway!

    I just saw the picture, new to this site.

    Maybe when I finish the 18' one I am (ever so slowly) working on, and if you survive your "hold my beer" moment with that 10 hp motor, we can trade. :)

    Reckon I lost my man-card...I...got scared... :) watched lots of You-Tube videos...big difference in 6 hp and 10hp! And big weight difference whether 2 cycle or 4 stroke.

    Bought a new Suzuki 6 hp instead.

    Shari I got my oars and leathered them up...I think 6.5’ would have been fine and these are 7’ using formula. I made some cool oar holders for stern to get them out of boat for running outboard. I finished my boat! Now for improvement to trailer running boards.
