Team Macif to join the Ultime trimaran club

Team Macif have added their support to the Ultime class with VPLP scoring a design request for an oceanic racing trimaran of around 100' to be skippered by Francois Gabart. An extensive and ambitious program of solo events ultimately working up to a solo round the world attempt.

and an article on the dailysail:

I thought it would be interesting to do a comparison with the current holder of the record Francis Joyon and IDEC II and challenger Thomas Coville's Sodebo

My observation from the provisional specs is that VPLP are pushing the beam out relative to the Iren's designed Sodebo and IDEC it's still not extreme but will provide more righting moment. This boat will have a 20m (65') beam approximately vs about 16.5m (54') on Sodebo and IDEC.

Macif

A trimaran of about 100 feet long in the final category, intended for offshore navigation alone.

Length: 30 m
Width: 20 m
Mast height: approx. 35 m

and for comparison Groupama3's specs, this is the Jules Verne trim so the mast fitted for the Route du Rhum was shorter (anyone know how long the "short" mast is ?). The sail area and mast height were reduced for the Route du Rhum when Franck Cammas solo raced the boat to victory.

Macif Test Boat

Striking new 24' foiler from Macif/Francis Gabart :
This boat is being used as an experimental test boat close to scale of the full size Macif to test foils and foil combinations. In the picture below you can see two different ama foils both of which work like uptip foils with intrinsic altitude control. Both amas have rudder T foils.

NOTE: One of the French guys on facebook claims that the daggerboard has a "horizontal plane, trim everything". Just spectacular if true!UPDATE-no evidence found for this claim anywhere so far.

Macif Test Boat

Martin on http://www.catsailingnews.com/2017/0...maxi.html#more
says that Macif is testing a foil on the daggerboard. Still can't find any corroborating evidence(like words or pictures) from Macif though.

UPDATE---Martin advised me today that he had talked to Francois Gabart and there is no daggerboard foil being tested on the converted Diam 24.
