I went out at Big Left at Flinders yesterday for my first session in sizable surf.
First a question to the wave experts. During the power strokes when catching a wave I sometimes have to swap sides and can miss the handle of the paddle or otherwise ending up doing a few limp little paddles. Is this a sign of a too long paddle or just lack of hard paddling skill?
Big Left is a deep water reef so the swells jack up from nothing as they hit the reef then thicken out as they pass by. It was quite difficult to catch the waves. The offshore breeze would push me back as I tried to stroke in. I had to sit well inside and paddle onto the breaking wave.
I was very careful to not freak out the surfers. Big Left is a pretty serious break and a long paddle out so you don't normally get beginners out there. Paddling a surfboard out there is usually a bit of a marathon but on the SUP I could launch from the beach car park and casually cruise out.
I was concious of being a bit of a gumby on a paddle board but the surfers were all cool and friendly so I was able to get amongst it and go for waves.
There are lots of reefs at Flinders so you get lots of short swells coming in all directions. At first it's a little embarrasing to be standing there waiting for a wave and have a sneaky cross-swell knock you off the board. It's a great antidote the the master-of-the-ocean-universe feeling you get when standing scanning the horizon for approaching swells. It's even worse if you hit the paddle with your head. Ouch!

I only really caught one good wave in 90 minutes but that ride was easily 200 metres. I gave myself heaps of hoots and found myself waving the paddle in the air riding out the last reform. Even the surfers commented on what a good ride it was.
On the small waves I rode in the past the Starboard 11'2" felt very immobile and hard to turn. On a bigger wave it felt quite nimble and I could comfortably turn back on the face. I am always surprised by the force on the paddle when I dig it into the wave face. So far all the SUP surfing I have done is foot steering. Paddle steering is not as easy as it looks.
My wave catching technique is to stand side on and wait for an approaching swell. As it approaches I start to paddle and use the natural turning effect to turn the board onto the wave. I give a few late acceleration strokes and away we go. My fast paddling side is on the left. ie. holding the paddle with my left hand and pushing with my stronger right hand.
Riding the white water back to the beach is fun but when a SUP hits a back wash it can stop dead. The result is a quick, involuntary run to the nose, until you reach the end of the leash and face plant off the front on the board.
