The SAM (Seakindly, Anti-Slamming Monohull) was developed by Navatek Ltd. and is optimized for very high ride quality, improved overall seakindliness and stability at rest. The SAM comes in a 30' and 40' versions. The hull features a variable deadrise hull with a pair of tunnels and sponsons/amas that reduce slamming, pounding and stuffing. This design allows the boat to be operational in sea levels greater than 5 feet.

    - Reduced slamming, pounding and stuffing

    - Forward low center of gravity for flatter running trim and less pitching

    - Good payload capacity

    - Prop or water-jet propulsion options

    - RIB and USV options available


    - Features a slender, variable deadrise, main hull stabilized by a pair of fine amas (sponsons) connected to each side of this hull by a transverse structure

    - The transverse structure creates two entrapment tunnels that capture water at low speed; entrained air/water at moderate speed; and air at high speed
