One aspect of the present invention relates to a method for making a boat. The boat includes a port side positioned opposite from a starboard side. The boat also includes a floor and stingers supports positioned within the hull. The method includes providing a insert having two spaced-apart elongated portions interconnected by at least two spaced-apart transverse portions that extend between the elongated portions. The elongated portions are sized and relatively positioned for one of the elongated portions to extend along the port side of the hull and the other of the elongated portions to extend along the starboard side of the hull. The method also includes positioning the insert in a chamber defined between a male mold piece and a female mold piece. The method further includes providing fibrous reinforcing material that surrounds the insert within the chamber. The fibrous reinforcing material includes portions positioned between the male mold piece and the insert, and also includes portions positioned between the female mold piece and the insert. The method further includes transferring resin into the chamber between the male and female mold pieces such that the resin envelops the fibrous reinforcing material, and curing the resin within the chamber. As the resin cures, the resin enveloped fibrous reinforcing material hardens to form the hull, the floor and the support stringers of the boat.

The boat of claim 1, wherein the platform includes a floor with a finished top layer. 10. The boat of claim 9, wherein the finished top layer includes gel coat. 11. The boat of claim 1, wherein each of the seamless connections that connect the planar top surface of the platform to the hull, the upper ends of the stringer supports to the platform, and the lower ends of the stringer supports to the hull, is made of a fibrous reinforcing material. 12. The boat of claim 1, wherein the stringer supports extend lengthwise along the hull, the support structure further including a first transverse support and a second transverse support extending between the stringer supports. 13. The boat of claim 12, wherein the support structure defines a front storage compartment positioned in front of the second transverse support. 14. The boat of claim 12, wherein the support structure defines a middle fuel-tank compartment positioned between the first transverse support and the second transverse support. 15.
