Therefore: Ama size is far too small unless:
a. Vessel is never taken into high seas.
b. Vessel is never sailed in high winds
One possible fix for this is to change the rig. Specifically think about going paraw rig or as James Wharram calls it Tiki rig. This changes main sail to a crab claw sail and will allow you to sail with less heeling, albeit perhaps a little slower.
With some helpfully sailing buddies on Boatdesign.Net Forum it is cleared first, that the designer was Andre Allegre
. He is that one who designed the legendary racing
trimaran Pen Duick IV/Manureva
(20.5 meter lenght, built in Aluminium) for French sailing legend Eric Tabarly
For this historically important part of trimaran history
I run into the wall of "language barrier". Would like to understand the French documentary about A.A.
The Trimaran was designed byAndre Allegre
, and one of the boat builders was Rober Artigues
in Beziers. He owned the boat yard "Constuctions 9 Écluses" which was renamed later into "Midi multi-hull".
The origins of this model Allegro probably can be counted in 1980/1981. It seems different models have been designed by Andre Allegre, e.g. Allegretto Croisic and five other versions (some of which had an inboard engine)...
...plus two stretched versions: Allegro Allegro and Super 30 (with a bigger trunk astern).
In totally it seems that till 2010 had been built around 60 boats.
The upper shown Allegro probably had the tanks
(water + diesel) in the demountable amas, which were bolted each with 4 screws to the mainhull. It was a significant design feature to deposit these tanks
in the amas. Maybe thats why it looks like they lack of volume and take the risks to undercut the waves with nose diving
All the infos are "datas delivered from mouth-to-mouth". So I dont have any guarantee for now that its the truth. Yet it would needed a fact based proof of the boat's history.
