A hull assembly is configured to transport a human user in water. The hull assembly includes a bow, having a bow concave portion. A port hull is joined to the bow. The port hull is adopted to accommodate a first foot of a human user. A starboard hull is joined to the bow and offset from the port hull by the bow concave portion. The starboard hull is adapted to accommodate a second foot of the human user. When a first port hull weight varies from a second port hull weight, the first port hull vertically deflects relative to the second port hull to increase the balance and stability of the human user and increase maneuverability of the vessel.

## Background
RELATED APPLICATION
This application claims priority to provisional patent application U.S. Ser. No. 62/145,358 filed on Apr. 9, 2015, the entire contents of which is herein incorporated by reference.


BACKGROUND
The embodiments herein relate generally to vessel hull shape and assembly.
Prior to embodiments of the disclosed invention, a rigid single hull, inflatable or hard material, stand up paddle board when on water required constant adjustments in the participant's center of balance to maintain optimal bipedal posture aligned in its horizontal gravitational vector. The rapidly shifting center of balance was a challenge to correct because there was a constant and abrupt leaning (heeling) angle that was greatly amplified because the standup paddleboard is one fixed surface. As a biped that utilizes two legs, hips, knees and ankles to maintain its balance standing on this single abruptly leaning surface was much more difficult than being on two independently moving surfaces.
There have been many attempts to create two independent hulls under each foot. The other designs have suffered because on some your feet are either connected to the hulls or recessed in the hulls which is extremely dangerous and or the connection between the two hulls lacks the specific connection design to prevent the inner or outer rail edges from flipping/flipping in or out causing the person to slip off or between the two hulls and some of the connections suggested are of non-elastic material such as a chain. Many of the previous designs had the feet connected or recessed in part to compensate for the instability of the two hulls because the hulls were not properly connected meaning they did not solve the problem of the two hull surfaces from folding/flipping in or out which would cause the user to slip off or between the two hulls. Also, if a person's foot was connected to the hulls or recessed in the hulls and they fall their risk of drowning or injury was greatly increased.
Embodiments of disclosed invention solve, at least, these problems.
SUMMARY
A hull assembly is configured to transport a human user in water. The hull assembly includes a bow, having a bow concave portion. A port hull is joined to the bow. The port hull is adopted to accommodate a first foot of a human user. A starboard hull is joined to the bow and offset from the port hull by the bow concave portion. The starboard hull is adapted to accommodate a second foot of the human user. When a first port hull weight varies from a second port hull weight, the first port hull vertically deflects relative to the second port hull. On each hull, at the port bow concave portion there is very little deflection and there is more deflection moving further aft in a manner similar to cantilever loading. A user has the ability to choose port to starboard and vertical movement intensity simply by adjusting one's stance position. By modifying stance position and increasing the cantilever intensity the hull now weighted acts like an aileron on an airplane, slow that side down, the other hull keeps moving fast, thus turning the board at an accelerated pace.
In some embodiments, the bow can further comprise a generally triangular shaped forward portion which is rounded on a port bow and a starboard bow while flat on a bow deck and a bow bottom side. The bow can be attached to a bow forward d-ring, a bow forward port first d-ring, a bow forward port second d-ring, a bow forward starboard first d-ring, a bow forward starboard second d-ring, a bow handle, and a bow concave portion d-ring.
In some embodiments, the port hull can further comprise a port hull port side, extending from the port bow. A port hull aft side can extend from the port hull port side. A port hull amidships side can extend from the port hull aft side. The port hull amidships side can be smoothly joined to the bow concave portion. The port bow can include a port hull top side and a port hull bottom side. A port hull amidships handle, a port hull aft handle, a port hull fill port and a port hull deck can be attached to the port hull top side. A port hull bottom side inboard fin and a port hull bottom side outboard fin can be attached to the port hull bottom side.
In some embodiments, the bow can further comprise a generally triangular shaped forward portion which is rounded on a starboard bow and a starboard bow while flat on a bow deck and a bow bottom side. The bow can be attached to a bow forward d-ring, a bow forward starboard first d-ring, a bow forward starboard second d-ring, a bow forward starboard first d-ring, a bow forward starboard second d-ring, a bow handle, and a bow concave portion d-ring.
In some embodiments, the starboard hull can further comprise a starboard hull starboard side, extending from the starboard bow. A starboard hull aft side can extend from the starboard hull starboard side. A starboard hull amidships side can extend from the starboard hull aft side. The starboard hull amidships side cam be smoothly joined to the bow concave portion. The starboard bow can include a starboard hull top side and a starboard hull bottom side. A starboard hull amidships handle, a starboard hull aft handle, a starboard hull fill starboard and a starboard hull deck can be attached to the starboard hull top side. A starboard hull bottom side inboard fin and a starboard hull bottom side outboard fin can be attached to the starboard hull bottom side.
In some embodiments, port hull water can fill the port hull through the port hull fill port. Starboard hull water can fill the starboard hull through the starboard hull fill port. In some embodiments, the hulls can be filled with pressurized air through the fill ports.
In some embodiments, an upper port hull grommet flap and a lower port hull grommet flap can be attached to the port hull amidships side. An upper starboard hull grommet flap and a lower starboard hull grommet flap can be attached to the starboard hull amidships side. An upper hull string can be connected to the upper port hull grommet flap and the upper starboard hull grommet flap. A lower hull string can be connected to the lower port hull grommet flap and the lower starboard hull grommet flap. This arrangement gives the rider the option to adjust the amount of movement between hulls. In some embodiments a tube can be inserted between the upper port hull grommet flap, the upper starboard hull grommet flap, the lower port hull grommet flap and the lower starboard hull grommet flap.
In some embodiments, a port hull upper amidships D-ring and a port hull lower amidships D-ring can be attached to the port hull. A starboard hull upper amidships D-ring and a starboard hull lower amidships D-ring, can be attached to the starboard hull. A upper connection member can be joined to the port hull upper amidships D-ring and the port hull lower amidships D-ring.
