To me the lack of a back strap and the weight of 6,4 kg for the 70 l GONG Hype are pretty much enough reasons to cancel it from the list of optional replacements for my Manta.
Agree.Ii don't think a rear strap is needed on the 80kg+ boads as there is a lot of windage with them. As the boards get smaller though, jumping is more likely. And not impressed with the video on the HIPE page showing a jump at around 10? seconds- freeze is and you'll see it's with a non HIPE board that DOES have a footstrap. Misleading.
Pity because with the USA box mast mount, should be easy to ballance load point relative to straps.

But I'm so new :D Still to get up and foil!

Hi Gunnar

with the posted range of 44L, 71l, 103L, 144L and 157L I wonder where the 120 somthing L is.
With 90kg naked, 103 seems tight and 144 almost to much. It does not seem to be very even.
Are there any changes in wight ?

Cheers Dirk

They will be bringing a 125 also in the near future. Just signed off on the final shape for that.

Interesting, they are reportedle doing a large glass fibre mast attachment pad too.

I'm curious as to which manufacturer will be first though, to customise the drop-stitch strand lengths to provide serious contouring.soft side rails aren't so bad but it's much more efficient to have actual corners, edges at the stern of the boards to promote planing and release of water in wake.

The technology exists, I will add some photos later on. I'm afraid the demand for such SUPs is not sufficient.. yet.

I'd really appreciate that!
I presume existing drop stitching machines have fixed stroke across both warp and weft of the top and bottom fabrice which would make glue-pressing of the PVC/vinyl etc flat layers fairly simple. But it can be argued that if the shape can be made as good, the rigidity close enough to hard board for feet and foil mast then the product can be considered superior to a hard uninflateable board. Currently the price point seems close to 2:1 for hard board vs high pressure inflateable board and I suspect the inflateable SUP technology is only around 10-15 years old. There is definitely room for improvement and manufacturers will tool up if it gives them a reputation for a superior product with the price not being a lot higher. I don't think the basic required modifications are even that difficult. For starters, the side rails aren't a big issue as a foil board never carves, it's sole job is to support the rider high enough to make starting easier and landing easier. The big improvements available are in modifying drop-stitch height between layers and moving the top and bottom material at independently controlled speeds. Between these two very simple changes, you can taper board thickness to the bow, place a small rocking point where hard boards wedge up for the kick onto the foil zone and also control overall curvature of the board. And that kick zone is important too because reducing the stern-tail height reduces the required material for a hard rear end cap which is the best way to improve board release performAance, both for pumping onto the foil and for releasing side touch-downs when in a heeled over turn.
