Input:
Question: A couple of folks have asked for the shaft diameter but I don't see any definitive answers. Does anyone have an actual calipered/measured diameter?
Document: It was misleading to see two pieces in the picture and no reference afterwards, so when I received my order, realized that the price is for one piece and not the pair. I bought 5 for 5 boats, and now I have two boats complete and one spare oar.
Not bad for the money; light weight but I think they'll do fine. I am now in need of a set of oar locks, I was under the impression they came with the oars - what came with the oars is a rubber sleeve that fits around the shaft of the oars so they don't slip from the locks, NOT oar locks.
I formerly had the standard aluminum oars from Sevylor and they felt okay. I was confident if I lost one it would float if it slipped out somehow. What I didn't count on was in the middle of the lake the actual paddle part would slip off the pole and I got stuck and had to shout for help and be towed in. So I paid slightly more for these collapsible ones and they actually feel sturdier even though the others were one solid piece.
These oars are better than the standard  that come with Sevylor boats but they are shorter than I expected and shorter than the standard but, the hand grips are nice and water doesn't run down the middle into my hands.
Not entirely what I was looking for. They won't attach into normal rowing oar locks. Get the right hardware, and they work OK as locked oars, but they perform much better as freehand oars.
The oars are really nice I took them out three times this weekend and rowed at least 25 miles and so far so good great product seems like they will last only time will tell though.
Oars are ok. They do not come with oar locks. Sold separate. Almost impossible to use with one person in raft trying to use both oars. If come with oar locks I would have gave it 4-5 stars.
These were a great buy! They are just as described. I needed them to be longer so I added 1 foot of aluminum tubing to them and they have worked great so far. I use them on my 12.5ft cataraft on the lower colorado in Yuma.....no rapids, just slow floating and these oars propel us just fine!
Worked fine down the North Santiam river in October from Fishermans Bend to Mehama. I had previously bent a kayak paddle on the upper stretch of river and was a little apprehensive about the durability of this oar. Happy I was to emerge wet, wild and intact from the raging tossing rapids of the lower Santiam.
These oars are awesome. I had been dealing with the plastic ones for a few years (replaced them twice because they snappped). These oars have no bend to them and are of high quality. They fit very well with my Sevylor raft. If you're looking for an upgrade to the plastic oars, these are definitely the way to go. You wont regret your purchase. They even come with a storage bag.
Answer: yes
