I'd guess that this is why:

Compare the lip on the left and see how it's starting to throw, but on the right it's just not happening, so the power isn't there.

Also look at the body positioning too.

Clay recommends the Carver CX boards.

I've got one and it's been very helpful to my surfing.

The Triton range is cheaper than the top of the line models, but it's just as good 👍

BTW I replaced the stock 78a wheels with harder 95a Park Wheels which are better on the bowls I practice on.

It's pretty smooth, but you're hardly using any of the wave ☹️

Try to get more top to bottom instead of rushing along the midline.

You seem to be starting your first bottom turn early when you're only half way down the wave, hold the drop for longer, then extend to the lip and you can access more of the wave face.

It looks nice and smooth, but your arms could be more engaged, it's only on the last turn that you really lift them. Point them at the lip and then push the coffee cup through the turn and look where you want to go.

Also you've got a lovely bowl to practice in, but you're barely using it 😉

Try to develop your path eg like this and then do figure 8s 👍

Ouch!

It's a bit difficult to see details, but you seem to rush out onto the shoulder which is why you run out of wave, that may be because (from what I can tell) you appear to be too side on, so even when you try to turn back, you're not able to twist there.I'd say your next thing to work on would be getting more front on which would help you turn back to the pocket and then you can go more top-to-bottom.

Rhys Llewelyn Nice!

A couple of other suggestions:

When you're coming down the ramp at the start, you look rather awkward and hunched over. Maybe try to keep your head up and compress the front leg.

The other thing is when you're turning, your left arm appears to be getting in your way and stopping you twisting as much as you could.

Try lifting the hand and, as Clay says, put your elbow in your back pocket:

Rhys Llewelyn You can add a second video in a reply to your own message.

Damn, that looks pretty good 👍

You're getting good extension on the upslope and compressing on the down, you're passing the coffee and your head is low so you're not standing on the board but leaning through the turn to be on rail. (I wish I could get that far over!)

I'd suggest the next thing to work on would be to look to where you want to go, for example on the last turn you're looking down at the nose of the board instead of where you're going next.
