I am still a beginner and also 70kg. I am using a 140 cm board with 9m kite and winds between 17-25 knots. I can tell you that 140 cm is very helpful.

I think 133 cm board will be too small...

Not to mention that the Cabrinha Custom model isn't very suitable for beginners. It would be so hard to get on it and to learn how to go upwind, because it has little concave and too much rocker.

First, I've never ridden a wake style board but my limited knowledge tells we the high rocker will make it very skatey and as Maj said, upwind will be more difficult to learn as a beginner.

Regarding the size; every board is different but I am 72kg and had a 130 x 38 North Gonzales and have a 132 x 41 Shinn Monk and as an intermediate rider I'm am very happy with those sizes, but as a beginner both would have extended the learning stage. I started off with a 138 x 40 all-round board with a low rocker and looking back I'm happy with that choice. Maybe you could get away with that size (133) on a low rocker board but I think that board will make learning harder than needed, but not impossible.

I don't know the going prices of that brand of kit or what you are paying but to split the kit to sell the board and then look for another is time consuming but that's only my opinion. It probably comes down to; is the deal worth the amount of time loss and mucking around...

Definitely not the first board to come to mind for a learner. But if you get it for a good price, go for it!

Thanks everyone for your advice it's hard enough to learn as it is so I will just sell the board and get another.

What board size would you suggest and what am I looking for in the rocker ?

thanks in advance!

There's a stack of beginner friendly boards out there. When you see one that is good value just check out the brands website or web reviews and they will state the rocker type.

With regards to size everyone will have a different opinion but at the end of the day it comes down to compromise; go for a smaller board and you will be able to keep it longer before you grow out of it but you will learn slower...get a bigger board learn and grow out of it quicker.

If I was starting out again I would have purchased a 138'ish board with a medium rocker and when I decided I wanted something smaller I could still use the 138 as a light wind twintip. Good luck...

I have a 141 x 42 underground tahee board for sale 300 bucks if your interested send me a pm good nic its what i learnt on

This is a good beginner board.

These days direct comparison of board sizes have become almost irrelevant as there are boards with soft flex and low rocker and nice freeride outline which fly upwind and hammer through chop even if completly undersized. With width increasing, the outline of the board has even more an effect as before. I have a 130x40 Caesar 2007 pro which is superstiff with no rocker so it goes upwind quite well even at 85kg...

The custom is a board with massive rocker* designed for wakestyle tricks. While the rocker will smooth the ride out a bit the board will have poor waterstart & upwind performance and also munch power up like crazy (great if you go big on your kitesize and want to hold an edge for wakestyle)... Going upwind with a 9m at 15 knots with that board will be really difficult, even though you only weigh 70kg. With wakestyle boards people often go huge and the boards tend to feel quite small.

*powerkite shop says the board has medium rocker but afaik the custom has more rocker than the Naish Motion board which they sell as high rocker.
