And it looks like David Raison, the guy who enhanced the chine and scowbow, will be the skipper too. Hand him the trophy right now, rest will fight for second 
new mini, who says it needs to be beautifull
- Thread starter JMOD
- Start date
Pleased to say that this is the beginning of an ongoing collaboration for DSS with SeaAir, and foils derived from my Q23 developments.New Mini

interestingly it still has the scow bow, so it doesn't completely rely on its foils
french do it better

yes it is
and it won't fit in the mini rule for the moment

In the current rule the foils cant extend outside of the hull, but wasn't that about to change prior to the next mini transat?

Yes foils not constrained by box rule for next Transat
I thought the foils could not extand past max beam in the minis, they changed the rules ?There's some more information here: http://www.seair.fr/
Not surprised that David Raison is involved with them.
They've got a different foil configuration on their website, but I think it might be an early rendering. Missing the T-foil rudders from above.
Seems like they have some experience building moth foils and booms. Interesting project.

Yeah, rule change: 2016
J-1 HULL
A Mini boat is a monohull, ie, a boat with only one flotation plane, regardless the angle of the heel between 0° and 95°, in which the depth of the hull in all its sections must not decrease in the direction of the axis of symmetry.
J-2 LENGTH
J-2-a The length of the hull must not exceed 6.50 meters.
J-2-b This measurement does not include:
-[SIZE=7pt] [/SIZE]the rudders, their foils if there are, and their fittings,
-[SIZE=7pt] [/SIZE]the bowspirit bobstay fittings,
-[SIZE=7pt] [/SIZE]the equipment to produce electrical energy,
-[SIZE=7pt] [/SIZE]the pushpits and pulpits,
-[SIZE=7pt] [/SIZE]the windvane pilots,
-[SIZE=7pt] [/SIZE]the safety hatch.
J-2-c No element added to the hull should allow its extension.
J-3 WIDTH
Without the boat healing, the beam must not exceed 3 meters.
J-20 APPENDAGES
The following are defined as appendages: rudders, daggerboards, foils, fin and any other device aspiring to create a hydrodynamic lift.
Appendages can increase the beam defined in J-3 once the start has been taken. However, the beam must not exceed 6,50 meters in the widest configuration.
Once the starting line has been crossed, appendages can increase the draft beyond the limit determined in J-4.

The Banque Pop team modified 198 as part of their validation process for the 60 which ALC is presently racing. Not sure if it was changed back after testing. There are some videos online of the boat

Thanks!, didn't know about this one yet.
Hasn't been sailed since BP finished with her and 198 is on the market in a "new configuration". Might be that the boards are included?
Pity that they don't mention the price.
Oh if I had money to burn.
Hey Hugh. Do you know what happened to the DSS mini? It was fixed keel wasn't it? Do you think it would be quick when refitted with a canting keel and a longer foil since they don't have to fit into Bmax anymore?Pleased to say that this is the beginning of an ongoing collaboration for DSS with SeaAir, and foils derived from my Q23 developments.New Mini
Also just out of interest, are you proposing something for the VOR? Seems like the system would be a good way to combine the foiling hype with the monohull roots of the race?
I reckon you need the canting keel for upwind sailing as the speed is too low for the DSS to work efficiently (lots of additional drag for very little additional RM). The transat is mostly downwind, though. And then the equation becomes the lighter you are, the faster you go, the better the DSS works. And a canting keel adds lots of weight. I imagine it to be comparable to take off speed of a foiler. The lighter you are, the earlier you pass that threshold speed where the foil provides an advantage.
Sorry that doesn't compute, canting has the effect of increasing RM for a given bulb weight, particularly when using a non hydraulic actuator, where's the extra weight over fixed? I would love a small canter for round the buoys, just let the keel down in each tack, needs less crew.

It computes, thats why you do not see small canters for around the bouys.
Want less crew, get a smaller keelboat. Hate to loose speed and want small crew, go catamaran.

The melges40 is the first around the cans one design canter to my knowledge. Yes someone also has to operate the canard/daggerboard, so not ideal for a small crew. Interestingly the canting keel actually provide some lift too when going fast down wind.
