Foiling Monohull - what would it look like?

If you take a unballasted flat very light  but wide mono - and put a foil on each side (dual rudders too) the leeward foil and rudder gives lift - the windward gives downforce - they are also in the water - but flaps make them pulling the boat upright.  In light winds all 4 foils can help lift the boat  out of the water. 

Basically in a match-race it will be the same as with the cats - wingmast and 1 or two other sails.

I understand the Volvo using foiling mono's, it just makes sense, on long windy legs where they can orient their course to the wind, waves and destination. But in a match race? It's going to be about the tech again instead of the race and the sailing. With a foil sticking out instead of down how fucking close can they get?
Light air mono foiling??? I understand the Mini's have been working on this and it is tough to stay on the foils.

Remember, going 20 to 30 in a sailboat is cool to sailors, but most could give a shit. Are they going to concentrate on the sailing or a media/tele event?? We need Exciting Racing and Sponsors. We need boats the the average person can relate to so they think they can sail too.

How long will the legs be and how much wind will be needed and what will be the limits of the course and wind range be?

How many dolts will be needed to pump the hydraulic rams for the foils?

Can we think of other stupid shit to raise the cost of the boats and limit the field again??

I'd venture to guess that there will be no manually powered hydraulics. It takes a pretty small battery to yield the equivalent energy of 3-4 pro grinders and it costs a lot less. Recovering 50% of the energy to cant isn't that difficult if your timing through the tack/gybe is good and incentives optimal turns, which will be an interesting challenge.

Add soft wings and get the crew size down to 3-4 and there's actually a chance it might develop some solutions that are applicable to club racing, which is something that foiling cats will never do based on storage footprint alone.

When you say soft wings, do you mean something like Camber induced or RAF type sails? I have not seen any soft foils on a big mono.
When I was able and windsurfed in the 80's while making sails, I made many of these for my board.
I really liked the RAF cut, very light weight and absolutely smooth on the leeward side like and airplane wing.
Camber induced with the larger sock looked good but I think the RAF was faster.

The boats will look like this:

I asked several ETNZ team members after the win what the next boat would look like. They pretty much came out and said it would be a foiling mono. Fully foiling for that matter. Minimum 60ft, soft sails with at least 10 sailors actually sailing, not cycloring. I asked the question, how could you tack/gybe and stay on the foils or even stay fast if you had to swing a canting keel around the place??? 

The answer surprised me. "If we're smart, we could do it without the lead!"

ie. No canting keel!

What would this look like?...

Maybe in ten years we will all need double wide births for our triangle shaped monos? Who knows...

This is what we are going to see I think. And it is going to surprise the sailing world. After all, they want to push the sport forward, and by doing it in a mono, it might actually trickle down to the rest of us real world sailors. 

Given the designers working on this concept and some of their recent work, I have total faith that it is going to be an amazing class. 

I have a feeling it's going to be a monster! Can't wait to geek out on the details with all you shmucks!

I must admit I like the idea of a foiling monohull if it ticks off the following:

1. They will sail in more breeze or any breeze up to 30 Knots

2. It drives mono development so one day I can buy a cruising mono that actually goes fast

3. It brings a new level of expectation as we are starting all over again

4. It drives ocean races to another level with the technology that comes with development

5. The list goes on

Reading this quote I get the impression that LR never really considered multihulls to be "proper" sail boats:

That would be dumb. I thought proper sail boats were boats that used a sail and the wind as opposed to a motor and diesel? Hence the sport and hobby - Sailing.

Therefore, how many hulls your sail boat has should be irrelevant.
