just came back from Nacra Europe, talked to the guys in the shop:
The 20 ft which is on the picture is used as a test platform for a /the new boat

it is almost 3mtr wide/ they said that the new boat will be even wider!!

the dagger foils are not the M20's but close and they are experimenting with these foils
"
I saw a couple of masts which they are testing with- huge

they refer to the boat internally as babyzilla, when I asked why, the response was that the boat will win any pissing contest on the beach and on the water and will come standard with bragging rights
