Does anybody know how different blade angles affect the performance of the paddle and what effect they have on paddling style and things like speed v how quickly your muscles get tired. I have two paddles cut to the same length. They are different shapes.



But don't appear to be too different in surface area.






But the blade angle is quite a bit different.



how will this affect performance?

I'm no expert but I find all this interesting.

I made my own paddles for years and they had no angle on the blade.. and I liked it.. I liked the way it didn't matter which way the blade faced.

I then used new C4 and realized there's something in this blade angle thing and I liked it better..I liked the extra reach..I like the way the blade released from the water.

I once saw a picture of Laird and noticed the extreme angle on his paddle.. It was a QuickBlade.

I've since tried them all.. The QuickBlade feels a but odd at about 14 deg.. It has even more reach than normal but the blade doesn't seem to start to work until the end of the stroke..Right where max power is.. I can see why Laird would like it.

The C4, Werner and Kialoa are about 12 deg and I think that feels just right.. (maybe that's because it's what I'm used to now).

Yesterday I saw pictures of the new JP paddles and they look only about 8 deg.. Almost straight.

I'm thinking thinking if you want heaps of power with a long stroke the more blade angle the better.

I think if you want to paddle with a faster cadence and shorter stroke a blade with less angle is better.

I think you still need some angle because it helps the paddle slip out of the water at the end of the stroke.. plus helps to stop lifting water at the end of the stroke..and also helps to lift the board with each stroke.

I know Dave Chun from Kialoa is working with Chuck Patterson on a new race paddle and it will be interesting to see what angle the blade is.

He did tell me that it will have a slight dihedral in the face but that's all I know.

I'm not sure if that helped any but that's my two cents worth..

Hi DJ,
Thanks for the info, I'm sure it will help a lot. Before I reply though, can we establish how blade angle is measured. I assume you take a straight line through the paddle shaft (handle), extend the line through to the ground and the angle between that line and the blade is the blade angle. If that is correct, the more bend the blade has away from the straight shaft, the more or bigger angle it has. Is this your understanding too? if so, my surfshapes has a bigger/more angle than my Kiakaha.

Yeah.. That's how I see it..

It would be interesting to hear what Woogie thinks about all this and why he uses so little angle in his paddles... (Only 8 degrees I think.)

The more you offset the blade face the greater the catch. The Kia kaha paddle is designed by Woogie Marsh one of the best one man outrigger (OC1) paddlers around.

Woogies paddle tapers in at the top allowing you to get the blade closer to the board and lets the water flow around the blade head more freely when you don't completly sink the blade.

A bigger offset and a larger blade give the most power but too much of either will quickly burn you out.Thats why we have seen smaller paddles like Woogies , Quick blade , Kialoa & Wener come on to the market.

OK, all good info but I'm still a bit confused. Here's my thoughts on these two paddles. I use them both and like them both however they are very different. The Kiakaha is my favourite out of the two. It feels comfortable straight away and it feels like it has a lot more power than the Surfshapes. If the waves are weak or full the Kiakaha is my paddle of choice, as I feel I can dig it into the water and really power the board forward. The shaft feels like it has a bit more flex in it than the Surfshapes. The downside of having all this power on tap, as Piros said, is I feel it in the shoulders after my surf. The Kiakaha definetly puts more strain on the muscles. The Surfshapes takes a little more getting used to and feels like it wanders a bit at first. After a couple of minutes though it feels fine and I don't think it wanders at all. However, I don't feel I can dig it in and power into waves. It has to be more of a quick paddle stroke style, but I don't feel so buggered after a session. Still, I like to use the Surfshapes when the waves are bigger and have a bit more push. I should mention that Rod makes three blade sizes and mine is the middle size, so his larger paddle may give that power feeling. I'm just trying to work out why each paddle behaves like it does. Is it the shape or is it the blade angle? And if it's both what design parameter produces what effect? It would certainly be good to hear Woodgies or Rods thoughts.

Thomo I love those graphics on that paddle and the shape of the blade. Do you have contact details for Woogie / dealer for these Kia Kaha paddles?

Also if you dont mind me asking how much did that paddle cost you?


Cheers

As Piros says the angled blade gives better catch at the front of the stroke.

The current wisdom is that you do all your stroking out the front and you have to lift the paddle about level with your feet. If you continue the stroke behind you they say you are pushing water upwards and also using smaller and less powerful muscles.

My Starboard paddle is quite wide and stiff. It's great for paddling along but in the surf it feels really hard. I dig in and pull hard and nothing really happens. Top speed is great but acceleration takes a lot of muscle. It's much better to start early with a series of short paddles building up to power stokes as the wave lifts.

With DJ's narrow Methane the paddle rips easily through the water and acceleration is immediate if top speed is less.

There are two real concerns using a wide paddle:
- Late takeoffs are harder because of the slow acceleration.
- There's a risk of injury with the greater leverage exerted by the paddle on shoulders and lower back

Websites not the best but it has contact details on it. I honestly can't remember how much it cost but it was pretty reasonable, certainly cheaper than the big name paddles. I'm pretty sure you can order custom colours but mine was just of the shelf from Roar Industries.

Hey Zimbo

Check out my gorgeous Kiakaha paddle!

Can't help with price as it was a surprise birthday present from husband. I am stoked with the colours and the graphics!

The Designs come out of Hawaii from a Paddling Family who have been in the industry for 20 odd years. Maui Kjeldsen designs blades, 1 man Outriggers and OC6 's. Woogie has some ideas and goes to Maui to get them put in place. We have got some new things in the pipe line. Hoping to get them out by Summer.

We do a blog but we are paddlers not IT workers

Great pic Sue.. and your blue Kiakaha paddle does look nice.

I'm looking forward to see what Woogie has coming up.

Are any of you guys coming down for the Mambo?
