Ships | Air cushion concept to lower ship’s fuel consumption by 30 percent | ekopolitan
I always wondered how they deal with air bubbles escaping the air cavity towards the transom interfering with the propellers. Shouldn't that aggravate cavitation? Ideally, wouldn't that require a center "trench" run towards the stern to funnel the escaping bubbles, and perhaps waterjets with side intakes?
