Question: what size/demensions are the blades?
Document: It is close to 240 for those who need to know in real paddle size.
It is the perfect size, good quality, to solve our expectations and I recommend it for purchase and enjoyment of kayak use, thanks
Enjoyed these paddles so far, am no professional but they're the perfect size for my inflatable kayak and really light and easy to transport. They come in half andseem sturdy.
On the water this paddle has been through some heavy paddling for a kayak and water splashing wars. But, during shipping I have had to return this size and the 84 inch three times due to being damaged either in shipping or in the warehouse.
I purchased this to use with an ocean kayak and was very pleased. The paddle is very light weight, breaks down easily, and works well in the surf. If you're using it in surf of any decent size, don't forget to buy a leash with it!
i got the 240cm size and it works great, much better than my old paddle.only one minor complaint, the foam grips are nice, but they tend to slide/twist while i'm rowing. but a little double-sided tape solved that issue
Needed paddle in one day. Prime Member, received in one day. I had purchased almost the same product at Dick's Sporting Goods for $75. Saw this puppy on Amazon. I returned the paddle to Dick's and while I was waiting in line I ordered this paddle.If u don't know what size paddle you need this is the process or at least how the Dick's rep explained it to me.
This is great for the kids - light, durable and inexpensive. The blades have a funky cirve to them  but it seems to work great.
I use this primarily in the Indian river lagoon. Nice and light, yet the blades are stiff and strong. Great value.
Lightweight, and the blades are curved just right. It's perfect for my needs. I'm using my kayak on a small lake only, so I don't know what to say if you plan on using this on a different type of water.
Answer: yes
