Abstract

Mejoras introducidas en el objeto de la Patente principal nº 449.240 por "Embarcación semi-sumergible", caracterizadas por el hecho de que comprende una cámara herméticamente cerrada completamente sumergida, una cubierta fijada sobre dicha cámara por medio de una estructura de soporte semi-sumergida, definiendo dicha cámara una amplia cavidad abierta y comprendiendo una abertura a través de la misma en la parte central de la zona inferior de dicha cavidad, comprendiendo adicionalmente varias aberturas amplias a través de la misma y cerca del borde de dicha cavidad, estando dichas aberturas cerca del borde de la citada cavidad y a aproximadamente la misma distancia desde dicho borde, siendo el área en sección de dicha abertura suficiente como para reducir eficientemente el suave movimiento de arrastre de dicha embarcación cuando la misma se encuentra flotando por una ruta marina fortuita.
