    I am interested in the concept of 2 fully submerged tubular hulls that travel deep eneogh to avoid wave action. Diesel engines are within the hulls and snorkel air and exhaust. The 2 hulls are joined by vertical struts to a wheel house and mesh deck area well above wave height level. The concept is like two mini subs ,in tandem ,remotely controlled from an above water low wave impact structure.Similat to an oil rig but much more slippery/fast.
    Does anyone know of links in this concept. Does it already exist?

    It's called a wave-piercer design. Here's a link to an example: http://www.goldcoastyachts.com/wavep.htm

    Keep in mind that if the hull (pontoon) is FULLY submerged beneath you... it will sink with the next gram of weight you add since there is zero reserve buoyancy.

    How´s about stability? As I understand submarines have very low longitudal stability when submerged. How does it work for this kind of hull?

    Pitch control

    Pitch could be managed by automated stern planes.
