10 foot oars

Postby Slim » Wed Mar 24, 2021 9:54 pm

After much deliberation, I have decided to go ahead with making a set of 10 foot oars for my DS1 #2077, “Sharky”

For the last 3 seasons of owning Sharky, we’ve messed around with the gamut of alternative propulsion from the original 30lb thrust Minnesota with a car battery, to a vintage Seagull long shaft, to a game fisher 3hp. My favorite, however has turned out to be my trusty ol’ canoe paddle, and I’ve gotten brave enough on a couple of expeditions to leave the motor behind. So far this has worked out well and have never gotten into too sticky of a situation that I couldn’t somehow maneuver out of! However, I’ve always had a motor or an extra paddler when really working against wind/current.
I’ve been thinking about the utility of some long oars, hopefully making possible longer becalmed passages, upwind crawling off leeward shores, and confident maneuvering in crowded coves. I havent’t really come across much on this forum in the way of oar experimentation for the Daysailer. A few people seem to have tried more standard 6 to 8 footers and found them usable but maybe a little too short. I’m going to try for a set of tens, which by most oar length calculating formulas still might be a little short. However, most of these formulas must be aimed at true rowing craft, which I reckon the Daysailer will never really be. However, I’m hoping that these 10 footers will be more than adequate and allow me to leave the motor well free for a couple of cold ones and the sunscreen!
And hopefully the sheets free of all the extra snaggers that a motor creates. Which brings me to a major drawback of shipping oars along for the ride,which is stowing them when not in use. I’ve eyeballed the carbon fiber sleeves sold at Duckworks which allows one to make any oar break down into two pieces. If the oars are successful, I might go that route, but for now they’ll have to stow in one piece. I’m hoping that the handle end will lay on the side deck near the side chainplate and be secured to it with some sort of bungee. The blade then would be hanging over the stern and maybe be secured to the aft side cleat or some other tie down point while sailing. I’m even thinking the shaft could have some sort of pad that fits onto it for comfort when hiking out!
So far I have roughed out the shafts from some ash I saved from the firewood pile. The shafts will taper from 2” at the handle end to about 1 1/4 near the end of the blade. I’m planning to make a flat blade about 30” long and glue it into long, wide kerf at the end of the shaft. That way the shaft will create a spine down either side of the blade. I don’t trust myself to go for a spoon blade. I worry that the shaft will come out a little crooked or asymmetrical and it may be good to be able to use either face of the blade.
I haven’t thought too much about the boat setup, other than oarlocks mounted somehow on the side decks and maybe a rowing seat that fits on top of the centerboard trunk just forward of the thwarts. Hopefully the oar handles will clear the main sheet and I won’t be bonking my head on the boom!

A number of people have fitted oars to their DS, and some have written about it on the forum.

Kudos for building your own!

I've rowed in one forum members boat. His oars were shorter than 10' because of where he stowed them. That may have affected the experience. I'm also taller than the person for whom the seat was fitted, so not the best condition for a test. Task was to get from the launch to the slip in a small marina.

Looking forward to hearing from you how they work out in practice, particularly for any longer distances.

(Otherwise, I'm still waiting for someone to report on a yuloh single oar on the transom and whether that setup would be workable on distances over a 1000'.)

I have been thinking about the single sculling oar. I found a place called Scullmaster that makes a lock that clamps on the transom and was going to possibly try it out this summer. I think it would tick all the boxes I need ticked.

Please report back, how well it tick(l)ed all your boxes.

Here is a picture of what the former owner installed on my Daysailer II. I have since removed. I think the seat and oarlocks worked well for storing the oars along the deck.

Alright, I'm curious. What's the black thing mounted on your center board trunk?

That is the rowing seat. It was a plastic chair seat mounted on a wooden base that strattled the centerboard trunk. I never sat in it but it appeared to be quite sturdy and it did not damage the trunk at all. The oarlocks were mounted with 4 bolts to the top of the deck combing. The access ports were for access to the fasteners.

Thanks for the pictures, that’s about what I was thinking, minus the fancy plastic bucket seat! Since I have a DS1 I’m not sure that the row locks will work out as on your boat. It’s hard to judge the angle that the oars will be at throughout their strokes so that they don’t bump either on the wooden coamings or on the rub rails. Think I might make a temporary block to hold the row locks that can be clamped in different positions in order to dial it in...

On an older DS 1, you just mount supports outside the wooden coamings, but high enough to clear them.
