Flat water, 5o mtr run up 6ft pitchin wave over 20 kts,whatwould jump the higest,wave , slalom , or speed?No arty stuff just pure altitude,higer than a kite,to set ahighest jump on a windsurfer is like brakin the 50 kts barrier

A race sail would give you further lift once you layed it over horizontal

Pitching wave as in pretty hollow? Waveboard or FSW cos I reckon you'll need the rockerline to fit in the wave as it runs up... a slalom or speed oriented board will start to push thru the wave face a bit.

a more gradual ramp - maybe a freeride with fair bit of rocker.

I agree with Elmo so I reckon you need 30kn, a big FSW cos it has enough rocker but can be fast, with a slalom fin and a 5.0 race sail.

Jonas Ceballos gets pretty high

That, I think, is just a fast wave board, i.e with a slalom rocker rather than Evo style with lots of tail rocker. They say a powerful sail is best too. Sailworks claim their Hucker is a you beaut jumper. I guess it's a lot like a Naish Force or an NP Alpha or a Gastra Poison.

You're pushing poo with a pointy stick though if you think you are going to beat a kite for altitude. Haven't you seen the Top Hat video?

This is Dale Cook in action at the Gorge.
The sails a Hucker and if I remember correctly the board is a highly reinforced slalom design so he gets the projection, his sail work is beautiful giving extra lift and great hang time. Looks kinda like he's using a Tectonics slalom fin as well for extra speed

I think a slalom board and race sail for sure. You can just go so much faster into the wave; speed = height.



Robby Naish gets pretty high and this isn't really a very steep wave when he hits it because he's out past the reef break.

Yeah those Naish jumps from RIP were exactly what I was thinking when reading through this.

Thanks elmo,nice video.But whats ,and where can i geta board like that? Kombat with a slalom fin, would that be the go!Justt looking for a board shape for max altitutude thats all, why cant we get a board designer that gives a specific shape for pure altitude.

You can use slalom boards but as they are constructed as light as possible the coming back down side of things may not give longevity to the board.

Trying to remember the article on Dale Cook, I pretty certain he has custom boards made for him which were based on slalom designs but highly reinforced, I'm pretty certain he said they were generally heavier than of the shelf boards due to the extra strength built in to handle the landings (I'll try and find the page)

The other alternative is something like the freestyle waves which have a good turn of pace (some guys use them for blasting) and are designed for jumping, chuck a decent fin in it and it'll go quicker.

The problem with the newer slalom boards is that they are all getting wide which is not good when you're up in the air. So maybe an older narrow board, or imo the ideal board would be a earlier model JP FSW, say an 03. I had one, they're incredibly fast, launch well, but still well behaved.

The other option is the Excocet cross boards, again quite fast, launch well and controllable.

The best board I found for control once in the air was my Acid Wave 04. For some good reason, probably it narrow shape, it was effortless you didn't even feel the board once it was flying.

Wave shape is important no? You'd want a wave that is spilling and ramp-like, not pitching and round:



So then you'd need to just be going as fast as possible. I'm going to say slalom gear. I think on "The Windsurfing Movie" there are some helicopter shots of Naish flying on some slalom gear, yes?

No I still think a hollow pitching wave... cos you'll hit it right where it is vertical... we are talking height here ..... so you want 100% of your forward energy transferred to vertical motion

The fastest slalom board you can get your hands on, wide tail would be good as it won't punch through the top of the lip early, the most verticle wave possible. Construction, you don't really care about the landing do you ? or control in the air ?
Don't you just want to hit the most verticle ramp at the highest speed and just go for pure height, don't worry about the landing or handling or any other damage. Go the height.

Hey can we have a GPS height challenge ? Do GPS measure height ?

They can, but not accurately enough. Plus or minus 10m I think.

You need a laser distance measurer thingo on a tripod which measures incline. So as the guy peaks his jump you measure how far away and at what angle of elevation (azimuth?) so you can calculate height. Bit like a surveyor.
Hard to keep the dot on him, but rooolly accurate if you can measure that distance spot on.

Imagine a few pros in 30kn plus smashing 20ft vertical faces for pure height. Then the BS stops and it would be an awesome show......

i requested this back when the gps thing kicked off when there was talk of trying to get the wave guys involved.

other than some fairly blunt responses i was told that gps devices couldn't accurately measure height due to the curve of the earth or something in relation to the satelites or something.

my head hurts.

maybe this is not an issue now with the new gps devices.

You would need a flying GPS similar to the units used by hang gliders which give a more accurate measure of height.

I did wear mine when I went out for and (attempted) wave sail to see the tracks afterwards, unfortunately to smaller sail and a plummeting breeze just showed how far I had to swim

Oh well, that's the first swim in over the reef out the way for the season

Will wear the little black box when I go out next to see if I can get any usable data
