Tavi, you are an amazing waterman! Thanks for sharing and showing that longer boards can still rip! Thanks for teaching windsurfing too!
I came really close to buying an Airbolt before I decided to build my own. My design was influenced quite a bit by that board.
Reading through the comments above it seems we all agree on most things, here is a summary.
We all want to uphaul, some want or need more of that feature but none are willing to ride sinkers.
Thickness is not a horrible thing.
Many of us are starting to realize that board aft of the foil is not the end of the world, and it makes for a user friendly low rider with few cons to the high end.
Maneuverability is improved by bringing the sail closer to the foil and for a given length swing weight is reduced if the foil is moved forward on the board.
The riders that are pushing short and compact to the limit have access to strong wind regularly and ride at a really high level. The rest of us are happy with a little more float, length and board in front of the mast.
I found it interesting that on Simon's recent custom he kept a really short length but flattend the rocker line forward (thickness) and ended up digging the fact that the board was easier to tack while at the same time there were no cons on the high performance aspects.
On my new board I increased the thickness and volume in and forward of the mast base (realative to the shred sled) to improve uphauling. A unexpected benifit was the abiltiy to pump the sail more aggressivly without nose diving, When I am feeling strong I can fly sooner because of it.
Bummer the industry doesn't want us anymore, oh well it's a ton of fun sorting all this out on our own!
