Abstract

L'invention porte sur un utilitaire de type embarcation à propulseur de jets d'eau comprenant une coque et un propulseur de jets d'eau. Ce propulseur comprend une hélice et des tuyaux de propulsion et est monté dans la partie poupe de l'embarcation. En général, l'hélice est montée dans une gaine fixée à la poupe. Les tuyaux de propulsion sont disposés dans une gaine, leur orifice d'évacuation se trouvant à l'extérieur de cette gaine. La gaine des tuyaux de propulsion est raccordée à celle de l'hélice. Ce propulseur de jets d'eau peut être installé et entretenu facilement et ne peut endommager d'autres éléments voisins. Cette embarcation a l'avantage de consommer peu d'énergie et peut être utilisée en eau peu profonde ou en eau polluée.
