Foiling has a long way to go before it's going to be anywhere close to mainstream.
I thought about going out that direction but any cost benefit couldn't be found, not even with binoculars. The hurdles were large not only from a design and build angle but all the peripheral stuff like parking, maintenance, Regs and more. Even if you did you'd end up being the freaky 30ft racing the 50fters and that would be a do OK or lose by a week situation depending on the weather.
Look at the racing the 'not quite usual' boats get i.e the Overloads, canters and so on, it's not good hence you see few leave their berths and those that do tend to be heading for a ship after being sold offshore. The NZ racing scene as much as it talks a big game it is not a fan of 'unusual'. Maybe if someone built a fleet and dropped them in at once it maybe the catalyst to build off but doing a one off does put you on the fringe and a fringe that often is not treated well.
Or maybe develop races that these sorts of boats would be good for which then may start some design changes and tweaking. But again trying to get races like that up and running is also not easy if even possible. I've been hunting for a big distance race for a few years and there are bugger all and the few that are there are designed and set up for fast 50fters not a range of boats in a range of configurations. I can't find a thing for smaller boats bar a organised rally to Aussie and a passing side thought sort of a semi race for big AWB graders you can get dumped in....then I'd suggest history shows your quickly forgotten about.
Disappointing a country that once rules the waves due to it's get out there, knock up a mates cunning design in the back shed and then take it all to the wet stuff then the world, mainly in the 30 - late 30ft range, now actively is working against that very thing happening in the future. That suppression of what NZ was world beaters at and was a large part of its sailing culture coincided with a sudden drop of new people coming into the sport, the death of NZ yacht builders, decreasing big races and decreasing fleets.
As much as I try I can't see the future improving. All I see is a growth in AWB's that sail non-extra divisions and a pile of older boats slowing disappearing to due to excessive costs and bullshit regulations.... and the lack of enough things to incentivise people to put some yards into improving them.
NZ's boating future is very much in 6.1 to 8mt tinnies with big f*ck off outboards on the back, yachts don't feature.
