High speed ship with tri-hull

A system for assisting a vessel in achieving a plane operation state, the vessel comprising a planing hull and a cruise power source having insufficient cruise power to achieve plane state operation from a fixed configuration of weight and trim, the system comprising:

• a boost power structure separate from said cruise power source, said boost power structure configured to be deployed and retracted, said boost power structure configured to deploy extending from a side of said vessel, and said boost power structure disposed longitudinally between amidships and a stern of the vessel;
• said boost power structure configured to be deployed at a speed less than a minimum planing speed;
• said boost power structure further configured to be retracted at a speed greater than said minimum planing speed;
• said boost power structure comprising one or more engines, each engine of said one or more engines operatively coupled to a respective thrust producing device of one or more thrust producing devices;
• wherein the vessel has a tri-hull hull cross section having at least three downward projections.
