navire à sustentation

This term includes but is not limited to hovercraft, which are generically known as ACVs (air cushion vehicles). It also includes "navions", so-called ground effect vehicles (GEV), which look like aircraft (souped-up seaplanes) but are not classed as such since they can't fly freely in the air:

Hovercraft was originally a specific and trademarked term but is now a generic one - I think... Not an expert though.

I reckon there is no one term equivalent here either, and that the FR term is as you indicate, Charles. I realize that we do not have an extract from the original, although the Asker does say that hydrofoil may be included. That may not be correct.
In any event, a descriptive solution is probably the way to go. Note that the Hydroptère is apart.
Would be nice to see the source text.
Gotta go. Interpreting job. Pff, inside. Frist sunny warm day in ages! Still, Paris can be beautiful in spring.

Thanks! I think the English word for "sustentation" is "lift" (aerodynamic or aerostatic in this case, since there are presumably no water vessels that work by electromagnetic lift). What you say seems to confirm that navires à sustentation are essentially air cushion vessels and ground effect vessels. Hydrofoils are explicitly excluded in the French definition I quoted, though they do use aerodynamic lift, as far as I can see. There doesn't seem to be an English term like "lift vessels", unfortunately.

@Charles

Le terme général est sustentation aérostatique qui inclut tout


On peut distinguer plusieurs formes de sustentation :
la sustentation aérodynamique, (avions, avions à effet de sol ou navions, hélicoptères, etc.),
la sustentation aérostatique, (véhicules à coussin d'air), navire à effet de surface, aéroglisseurs, aérostats,
la sustentation électromagnétique, train à sustentation magnétique,
la sustentation diamagnétique.

The first step is to be clear about what "navire à sustentation" does and does not include. If the official definition in France is applicable here, it does NOT include hydrofoils, because no part of the vessel may be in contact with the surface. This is from the Arrêté du 11 mars 2008 modifiant l’arrêté du 23 novembre 1987 relatif à la sécurité des navires:

"Navire à sustentation : aéroglisseur, navion, ou tout autre navire conçu pour évoluer à proximité de la surface de l'eau, sans contact avec cette dernière, et à une altitude inférieure à la longueur de coque de l'engin. Cette définition exclut les hydroptères, portés par des foils en contact avec l'eau."

Aéroglisseur is ACV and navion is WIG (wing-in-ground effect) craft or Ground Effect Vessels (GEV). However, there doesn't seem to be a single term in English for both; all the sources I can find treat them as separate categories.

Generic s "navire à sustentation"
hydrofoil is hydroptère
Air cushion vehicle is navire aéroporté

Abel, I agree, hyrdofoil, foiling craft and AVC (air cushion vessels) are all types of boat which fall into this category. We need the name of the category that covers both though.

Ghyslaine, I'm going to keep looking. This may help generally for the rert of your text, just maybe. http://www.maria-online.com/books/article.php?lg=fr&q=Navire...

Il y a les hydrofoils et les air cushion vehicles
