I have't been around for a while lately but it has not stopped me from experimenting with things.
My latest pet subject is paddle blade angle.
The current crop of paddles being offered and recommended this season has the blade angle somewhere from 12 to 14 degrees.

I disagree with this angle for wave riding, my current wave paddle is set at 10 degrees ( remember I make my own paddles ). This angle does not dig into the waveface to deeply for bottom turns and is great for trawling behind you in the whitewater or the wave face. I have been using 10 degrees for a few months now and swapping back to 12 degrees, and definitely prefer the 10 degree one.

Just check out some of the youtube vids from PSH and you will see him twisting the paddle over to the front of the blade on the wave face for a smoother skim with less drag and catch.

What are your thoughts?

I think Laird and Dave uses about 14deg.. I think the more angle may give more reach at the start of the stroke..and more power at the end of the stroke.

I think the angle has something to do with how it releases from the water at the end of the stroke.

I have also noticed a lot of guys flipping their paddles to slide the face of the blade rather than the back..and it would also give better clearance.

We need Blane to chime in and make a comment.

I'm happy with the angle on my Kialoa's... whatever they are..

Hi Rod

I've been experimenting with blade angle as well, but in the opposite direction. Having an outrigging background it was always important not to follow through with the stroke too far as the paddle blade angle would have a negative action of pulling the canoe down into the water therefore losing glide. Suping with a 10 degree angle blade this was even more of a problem. I am currently using a 25 degree blade, for downwinders it feels fantastic as I can stroke past my feet and the blade angle is still relatively straight in the water, and for surfing I find that the blade is closer to being parellel to the waters surface which doesn't put the brakes on as much. Mind you sometimes you really need to dig hard to get that turn happening. My next blade angle will be 18, and the shape very similar to that of the methane.

Hi guys, I think that for flatwater paddling, open ocean paddling blades with over 10 degrees of angle are fine. What the optimum angle is at this stage who knows.

I am going to argue that it there is a fair bit of misleading info about paddle angles and the reasoning behind the designs, especially to do with wave riding.

As far as I can feel, the biggest miss-info is that we need paddle angle to keep the water when paddling from pulling the board down and that this will stop you from planing, well this might be true currently for canoe paddling but it is not happening to me when I paddle my SUPA boards.

I usually cruise out the back using lazy chicken winging strokes, not expending too much energy. That is until a set appears and depending on whether it is trying to claim me or I am trying to claim it determines my fast stroke style. What we have to remember is that nothing is set in concrete, SUPA paddling is still that new.

What I am arguing and looking at is wave riding specifically, it is just a useless movement to flip your paddle over to get it to trim better. It slows down your reaction time for wave moves, you actually have to think about turning the blade over to the correct way to use the paddle.

My current blade is a low area, mid aspect blade of around 95sq inches. The blade is flat, no dihedral, no recurve thru the blade length, with the mid aspect planshape. The mid aspect planform hurts a bit more to get going ( you can feel that there is more pressure on the blade) than a higher aspect blade. The only thing that is miss is not having blade recurve as I feel this allows the blade to enter the water much faster and easier than with out recurve, also the blade does not deliver quite as much punch at the end of the stroke when I rotate it out, is this a bad option? The blade still looks like it is in a vertical position when it rotates out to me , but then I am doing shorter wave style high rotation paddle strokes even when cruising back out the stroke is short, mainly because waveboards with their shorter length and increased rocker do not have as much glide as a pure paddle board so the stroke does not need to be as long.

Anyone else got any opions?

Dunno much about paddle blades - I have only ever used my global industries carbon paddle.

Since I saw the clips of Blane flipping his paddle face over I have been quick to copy him & find that I'm already doing it instinctively - I flip the blade to the front-side when I want speed and to the backside when I want to slow down/cut back

This is an interesting idea.

It could be that a SUB paddle with a "keel" protruding from the bottom may be of benefit to SUP especially in the surfing mode. I'll dig up the info on it and get back here. It was a feature on most ancient Polynesian paddles, some thought it was for stabbing as weapon, but it had a grander purpose.

That looks pretty cool, i wonder if it works as good as it looks.

To wind up grumpy longboarders in the lineup?

After reading about this paddle flipping business I couldn't resist trying it. You know what!
I liked it.

I was mulling over in the car on the way home last week about the paddle angle stuff Ive been talking about and the main feel that I did not like was when the 12 degree blade sunk deeper into the wave face and caused me to stall my bottom turn. The blade did not feel as loose as the 10 degree one.

The other cause could have been that the 12 blade was using a high aspect low area blade. The 10 blade was a low aspect blade with a wider tip, so maybe the narrower blade was a contributing factor to the stalling bottom turn. The narrower blade sank deeper into the wave as well as the larger hook affect of the 12 angle.

I have to make two new blades now to check this out.
