Solar powered boat

A method for powering a solar powered aquatic vessel comprising the steps of:

• providing a displacement hull having a V-shaped bow for cutting through water efficiently below a hull speed and an overall length about equal to a length of a waterline when the solar powered aquatic vessel is afloat and on an even keel,
• the displacement hull having a maximum hull draft at a station of the displacement hull that is located at about 30% of an overall length from said V-shaped bow to a stern of the displacement hull;
• the hull comprising a chine having a V-shape at a bottom of nearly vertical, slowly tapering inward side panels of the displacement hull;
• the displacement hull having a keel projecting downwardly away from a remainder of said bottom on the displacement hull from the V-shaped bow toward the stern only to a distance less than half the overall length, the keel angled upwardly at an end thereof opposite the V-shaped bow;
• the displacement hull comprising a single hull having a bottommost surface of the displacement hull extending from a first port side of the solar powered aquatic vessel to an opposite starboard side of the solar powered aquatic vessel, the displacement hull having a variable draft and a variable hull shape along a length thereof;
• the displacement hull having a flattened bottom portion at about a maximum beam length;
• the flattened bottom portion having a more flattened shape than a shape of the displacement extending from the maximum beam length toward the bow;
• the bottom having an approximately linear slope from the maximum beam length to a transom forming a stern of the displacement hull;
• the transom comprising a bottom portion positioned at or near the waterline when the displacement hull sits in the water;
• connecting a canopy to the displacement hull supporting at least one photovoltaic panel
• connected to a photovoltaic system positioned in the displacement hull, the photovoltaic system generating electrical power from a sun that is equal to or greater than an amount of the electrical power necessary to propel the solar powered aquatic vessel;
• attaching a motor operatively connected to the photovoltaic system to the displacement hull;
• generating the electrical power by the photovoltaic system from the sun that is equal to or greater than the electrical power necessary for the motor to propel the solar powered aquatic vessel;
• providing the electrical power to the motor and operating the motor to cause movement of said displacement hull at a first speed below a hull speed of the displacement hull of the solar powered aquatic vessel to efficiently power the solar powered aquatic vessel;
• and
• directing electrical power from the photovoltaic system by a charging controller to a battery when the photovoltaic system generates more electrical power than required to drive the solar powered aquatic vessel at the first speed below the hull speed.

A solar powered aquatic vessel comprising:

• a displacement hull having a V-shaped bow;
• said displacement hull having an overall length about equal to a length of a waterline when the solar powered aquatic vessel is afloat and on an even keel;
• a maximum hull draft at a station of said displacement hull that is located at about 30% of an overall length from the V-shaped bow to a stern of said displacement hull;
• said hull comprising a chine having a V-shape at a bottom of inward side panels of said displacement hull;
• a keel projecting downwardly away from a remainder of said bottom from said V-shaped bow toward said stern only to a distance less than half said overall length;
• said displacement hull comprising a single hull having a bottommost surface extending from a first port side of the solar powered aquatic vessel to an opposite starboard side of the solar powered aquatic vessel, said displacement hull having a variable draft and a variable hull shape along a length thereof;
• said displacement hull having a flattened bottom portion at about a maximum beam length;
• said flattened bottom portion having a more flattened shape than a shape of said displacement hull extending from the maximum beam length toward said V-shaped bow;
• said bottom having an approximately linear slope from said maximum beam length to a transom forming said stern of said displacement hull;
• said transom comprising a bottom portion positioned at or near the waterline when the displacement hull sits in the water;
• at least one photovoltaic panel connected to a photovoltaic system, the photovoltaic system generating electrical power from a sun that is equal to or greater than an electrical power necessary to propel the solar powered aquatic vessel below a hull speed;
• and
• a motor operatively connected to said photovoltaic system, said motor configured to cause movement of said displacement hull at a first speed below the hull speed;
• the at least one photovoltaic panel comprising a sufficient number of photovoltaic panels such that said photovoltaic system provides electrical power to said motor to cause the movement of the displacement hull below the hull speed;
• a charging controller configured to direct the electrical power exceeding an amount of the electrical power needed to cause the movement of the displacement hull at the first speed to a battery to store the electrical power.
