    Sorry Doug, but I do not have any more infos. Seems to be a trimaran with a tent for the night - something experimental like this: https://www.youtube.com/watch?v=-x-IaHTwqcE .

    [​IMG] But I am not sure.

    Thanks again Brian for the pictures of CATAPROA. I do not understand the design philososphy of hull design from Bernd. There seem to be only a small amount of static and hydrodynamic lift in the slender port hull. Is the suction of the swept up bottom at the stern (Bernoulli) able to compensate bow down tendency in a squall (as in Ian Farriers trimaran designs - http://www.f-boat.com/pages/introduction/features.html - "At high speed, the trimaran main hull planes early due to the low rocker, while the swept up aft section generates negative lift, which can actually lift the bow well out of the water. As a result, Farrier multihulls are very resistant to bow burying.")? I do not have experience with icarus design catamaran hulls.
