Is this thing gonna make us break the speed record, or is it just another North gimmick to break and cause havoc!

What do you reckon?

i can see where they're coming from but soon we will have air and gel foam foot pads and super padded harnesses.. haha

North are the Honda of windsurfing, allways thinking of new ideas, they must have alot of ideas men working for em... They now have a 3 piece mast as well..

I think this idea will work and i hope it takes windsurfing where the first rear shocks took mtbing...

Me and my brother want to buy some, once we can find a place locally that sells them.. we both think it would work

I love all the new ideas North keeps coming up with

I reckon it's crap Flacky.

It's been tried before (you were probably in nappys,....... ......doing year 12)

Lots of effort goes into trying to get the rig as low down to the mast base as possible, to improve efficiency, close the slot, get more drive through the mast base and into the board etc.

This just raises the centre of effort of the sail unnecessarily and allows the bottom of the rig to wobble around more than you want, reducing efficiency.

When it was tried before, I believe it did smooth the ride a bit, but the trade off with other things made it not worth it.

IMHO, a gimmick that will not take off.

I bet you would of said the same about the very first clamp on boom, wich i think North were the first to invent too i am a ideas man, my old man is a ideas man, my gran dad was a ideas man... so with this talent i have sat down and thought it over, and after thinking about it for half of a hour, i worked out it is possible. remember bonda my friend '' The power of dreams ''

And for your information bonda buddy, i wagged year 12 and went to work on a farm, and spent my free time learning to windsurf, with a 50 buck long board. It was the good old one design, ya got to love em...

another thing too bonda you sail with a Z boom who was the ideas man that thought of that??

It's true, and plain for all of us to see that you are an ideas man Flip.
......and it comes as no surprise that you come from a long line of ideas men. After all, ideas like yours don't just fall from the sky everyday

The z boom was indeed a great idea (thought it may even have been a product of your father or grandfather, perhaps)

By the way, are you sure that year 12 was the only year you wagged??

For an ideas man you have missed the obvious!! The real solution is in your name!!
Rather then absorb shock perhaps it should FLIP the rig for you!!

Imagine carving into a gybe, hands behind you back, wink at the girls on the beach and FLIP!! around it goes

I want one.

Great idea and possibly good for wave sailing but speed / slalom sailing there's one problem I see - difficulty closing the gap between sail and deck.

I agree that for wave sailing, freestyle it would be fine, but think for race/slalom and speed there is an issue.

As discussed above there is the issue of closing the slot - but that can be overcome I am sure.

Rather there is an issue of energy absorbtion into teh sprng device. Energy is generated in the sail and has to be transferred through the mastfoot to the board to drive it forward. If 5% of the sails energy is absorbed there is 5% less energy available to drive the board forward! Not real good in a race ;-)

heyI appreciate the concern which is been Exercises . The things need to be sorted out because it is about the individual

but it can be with everyone.

Must also be a reason why racers prefer tendon bases to boge bases. Ive tested both side by side on the formula gear and found the boge to have significant sideways stretch versus the tendon bases.

Rear shock's are only any good for going downhill. If you want to get the powerdown you need a hardtail!

The analogy here is its 'probably' great for flicky spinny or wave riding , But going fast as the original poster querried, probably not the ideal way to get MFP.

...but what would I know

I'd be more impressed by a reliable boge joint.

I dunno fellas! But i think its just another gimmick to fail us! Just like the North XT Mast Extentions!

Once those things start to slip, its just a never ending battle!

I dunno about you guys, but when i 'pop' a board to start a 'spock' i push down on the mast foot and then 'ollie' the board, but if i push down, and it springs back up again... i reckon the board will stick!!!

Who knows, it will be interesting how the boys in slalom go in the next coming weeks with this!

How many NORTH guys will be using them??

Not wanting to fan any fires here, but what don't you like about the XT? I've had one for several years, and despite buying several normal style extensions since, I still find myself using the XT on my big sails (as battered and tired as the extension is). I find I can fine-tune a few cms down-haul either way on the water in about twenty seconds. Very handy for the changing conditions I seem to sail in. Given the tension required for my cambered 7.0m, I've never experienced slippage. Maybe I got lucky!

back on topic, I thought all the stiffness in our rigs is designed to efficiently push pressure into the nose via the foot. This spring-loaded extension seems to undermine that chain-of-power, but I think if you're powered up enough, and not a speed sailor it might be useful for absorbing the board's pitch in chop.

I've used the XT for 3 years now without an issue. I rinse it regularly and avoid letting sand/salt build-up around the wheel and ratchet. I also move the rope around after a few months so that the tension is getting applied on a reasonably pristine section which seems to maintain good grip. Predominantly on a 7.8m North S-Type (3 cams) which would probably have a moderate amount of downhaul required. Can't fault it - great piece of kit that I'll be going with again for sure!

As for the shock absorbing mast base, I'll be giving that a miss.....

i thought the necessity to "close the gap" was a myth? according to guy cribb anyway.

I seem to recall that he said it was not something to try for.
The fact is that end plating a foil increases lift. I think the down side is that sometimes the foot of your sail is in the water.

aaaahhhh the Seabrite

.......Takes me back to 1987-ish

-I had just purchased a weird boom based on a hunch that it looked like a good idea. (maybe from an ideas man like Flips Father or Grandfather!!)

It was a Z boom, which just happened to have a Seabrite clamp on front end.
It had a wire that went around a plastic bracket and was a pain in the butt to connect. Then it had a plastic screw-in knob that was the fine tuning, tensioning device. ....and a plastic lever with a "frog" logo on the front (must be a French thing).

.....anyway, I thought it was the bees knees. I remember connecting it up and marvelling at how rock solid it was compared to the crappy rope and cleat crap we'd all been using up 'til then.

On my first run, I did a jump, landed, and heard a gun shot go off!
...it was my mast snapping, in a clean break exactly at the boom![}:)]
(my good epoxy excell mast)

Bees Knees, my arse.

Then I realised that the little cracking noises I had barely heard as I had tensioned the clamp were actually significant!!

Lesson learned. Have never over tensioned a clamp on boom since.

Just read on a uk forum that North/Fanatic riders G Cribb, M Pearch, and A Baker finished 1-2-3 in the latest slalom round using the North shock so it must have some merit?
Conditions were choppy and windy so the idea may work.
Might need to try it to see.

Ah indeed! That Seabrite clamp was a swine. I'd snapped too many Excel masts in the surf, so luckily I had a Rotho Super wave to try it on, and it was the clamp that burst!!

Come back Rotho, all is forgiven.

Make sure it wasn't a three man slalom race

Mountain Bike shocks have taken advantage of technology developed for motorsport. The shocks are able to be tuned to react differently to high frequency and low frequency impacts. What this means is it would be possible to build a mast foot shock absorber which would not compress under mast foot pressure, but would react to sharp impacts such as chop.

So if the mast foot height could be kept low, and it was built as a lightweight reliable Air shock, it has merit.

No idea if this technology has made it into the North shock.

Just had a look at the North Website. Looks as though it's using urethane bushes for dampening. About equivalent to mountain bike suspension 15 years ago.....
