just wondering about some techniques for wave sailing because every time I go out on the board I spin out is this because of the fin sizes?
I have 10cm fins on the outer fin boxes and 13cm fins on the inner boxes.

Lots of 85 liter quads use 16 rears...

And mast base back, less power, lean on front foot, sheet out to spill "excess" breeze, move straps forward.

How much do you weight? What board?

Wouldn't say lots.
14 is much more common.

My 100 and 110L come standard with 15.5 and 9 or 10.,

The sizing is right. Technique, sorry to say. Aidenduthie you'll have to go easy on the back foot pressure. No lateral pressure at all pretty much.

I'm assuming the fins are in good condition, not all ground up on the tips

Not really the fins fault. I sail 13s as a twin setup every now and they for extra looseness and it doesn't spin out.

Make sure you're using lots of mastfoot pressure and don't push on the fins at all. Harness lines back.

I weigh 70kg and have a severn nano 83

thanks for all the advice, so I need mast base further back and harness line's moved back further, and to top it off hardly any back foot pressure.

Also make sure your sail.is rigged correctly. Insufficient downhaul can mean you pull hard on the back hand and that force is transmitted to your back foot and can aggravate spin out problems.

It will also depend somewhat on sail size. The stock finset will probable balance out best with a 4.2-4.7 & be a bit touchier but usable with a 5.2, but try & sail 5.5+ will likely overload. The harness line placement & balance of the rig is important. For very powered sailing, I like to first find the no-hands balance point of my rig, then bias it just a cm towards the clew to ensure I am not overloading the back hand. If you have lines too far forward, as you get a gust your back hand will transfer the power to your back foot & you can spin out... As mentioned, If your sail is not rigged well the draft will move more & it will be more difficult to balance everything out.

What size board? Seems small. Otherwise go easy on the fins until you have enough drive / speed. Then you can load them.

And use harness lines around 30,32,34 depending on what is comfortable for you. These bring the rig more upright and will automatically gain more pressure on the mast base. You can play a lot more with the rig too while passing smaller waves or the white water. Sometimes I see people with 20 or 22.

What Manuel said, also try and put front foot pressure and make sure you're hanging off the boom to apply mast base pressure.

Most of all, don't forget to smile!

i had the exact same thing happen when i tried a wave board for the first time , not like my freemove board thats for sure

THANKS FOR ALL THE ADVICE HOPE TO SEE SOME OF YOU OUT ON THE WATER ONE DAY.
