YES Clark SIY 2016 - 2015 Review by The Good Ride

The Yes Clark S.I.Y. is a new custom concept for this year. They take the camber profile and base used in the Yes 420 but after that it’s pretty much all you……actually literally all you.  You shape it and make the rest yourself.

If you don’t surf then you won’t know who Clark is but if you do you will know that he provided blank foam decks to almost all surfboard shapers for like a generation. This is a pretty fun idea and a great concept for snowboarding as the custom snowboard world is pretty thin.  I can’t tell you how man times I’ve ridden a board and went man I’d truly love this board if I could make the side cut a little deeper or change the stance width to fit my stance perfectly and so on and so on.

We are pretty familiar with the camber profile of the 420 so it would be fun to play around with the shape, flex and sizing. This isn’t really for the novice or mid level snowboarder. It’s for a snowboarder with a surfers mentality.  However it’s a great idea for that rider who knows himself really well always wanted a powder board specifically tailored to their specs, conditions and riding style.

There are a few things that for the most part won’t be changed in the ride from the 420 :

** Camber Profile- The flat to rocker profile will guarantee a stable ride between the feet. It’s also going to be catch free.

** Powder- All rides will have this directional flat to rocker profile that has more rocker in the nose.  This will make it a really surfy ride for treating the mountain like you are on a wave. Of course it’s up to you to determine how far the set back will be and how off the tail surfy you want the ride to be.  Also the volume of the board will also determine how much it floats too and since it’s short it might be a good idea to go wider than your normal waist width.  Maybe not uber wide like the 420 but not something normal either.

** All boards won’t have camber anywhere in the profile so there won’t be too much snap out of the turns but this is a board for floating in powder and not carving so it’s not really that needed.

Now here is what you can control:

** You can make all kinds of shapes but the best will be something that is directional and probably tapered.  The Taper and shape is completely up to you.

** Turn Initiation- Complete control over this and you can make the board’s side cut allow you to turn on a dime for tight tree runs or make it best for straight lining or somewhere in between.

** Flex- you can go from med/stiff to stiff with the Clark SIY and that can change up the speed and butterability a bit.  I’m not sure how custom you can get with the flex from tip to tail but we’ll see.

** Uneven Snow-  You can control with your design the way the board will interact with slightly uneven to big bumpy snow. A 3.5 out of 5 flex will make it easier but also the side cut and shape will be big factors as well.

The rest of the stuff like riding switch, jibs and pipe don’t really matter.  This will be fine for launching off natural features.

To make this happen you go to and get it going through their site.
