All American Marine’s research and survey catamaran hull designs feature hydrofoil-assist technology that provides for shallow draft, enhanced sea keeping ability, and improves speed and fuel economy. AAM vessels are designed to reach the work site quickly, without crew fatigue, and provide a stable platform to ensure safe and accurate data collection.
The hull form of AAM’s research and survey vessels is a semi-planing type catamaran hull that employs a combination of symmetrical and asymmetrical sponson shapes, combining the attributes of both shapes in one hull. The symmetrical bow-section ensures directional stability in short swell conditions and following seas, while the asymmetrical amidships and aft sections ensure softness of ride and reduced wetted area which enhances comfort and economy. The catamaran hull has a high tunnel ceiling with a large opening between the sponsons, which allows free movement of wind-waves without slamming on the wet-deck. Also, horizontal steps on the inside of the tunnel walls act both as chines to deflect green water from the hull surface, and to break up the solid water into spray. The combined effect of these features produces a hull with low resistance, low vertical accelerations, and excellent performance.
