Abstract
A method of manufacturing a boat hull comprising: forming a foam mold of a predetermined shape and size from one or more pieces of foam; cutting at least one C-channel into said foam running in a longitudinal or a lateral direction within the foam; and coating said foam with at least one layer of reinforcing fiber and resin.
Claims18
A method of manufacturing a boat hull comprising:
- a. forming a foam mold of a predetermined shape and size from at least a first piece of foam and a second piece of foam;
- b. cutting at least one through hole into said foam mold wherein said through hole is positioned with a portion of said through hole in said first piece of foam and having a corresponding portion of said through hole in said second piece of foam;
- c. wherein the through hole in the first piece of foam and the through hole in the second piece of foam are positioned so as to be aligned upon securing said first piece of foam to said second piece of foam;
- d. coating said foam mold with at least one layer of reinforcing fiber and resin securing said first piece of foam and said second piece of foam together;
- and
- e. wherein at least one of the first piece of foam or second piece of foam comprises at least two different densities of foam wherein a higher density foam is positioned below a lower density foam.

A boat hull comprising:
- a. a foam core, said foam core comprising at least a first piece of foam and a second piece of foam;
- b. at least one recess defined in each of the first piece of foam and the second piece of foam;
- c. wherein the recess in each of the first piece of foam and the second piece of foam are in alignment;
- d. at least one layer of fiber impregnated with resin, said at least one layer of fiber impregnated with resin suitable for covering the foam core;
- and
- e. cutting at least one C-channel into said foam core running in a longitudinal or lateral direction within the foam wherein said at least one C-channel has a depth of between 1 mm and 100 mm and wherein said fiber is a reinforcing fiber positioned within the at least one C-channel and in direct contact with the foam within said at least one C-channel.
