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.
Claims15
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, said first piece of foam having a first density and said second piece of foam having a second density which is greater than the first density;
- b. layering the first piece of foam above the second piece of foam;
- c. 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
- d. 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 method of manufacturing a boat hull comprising:
- a. forming a first foam structure from at least a first piece of foam of a first density and a second piece of foam of a second density wherein the second density is greater than the first density, wherein one face of the first piece of foam is secured to a second face on the second piece of foam, and wherein the first piece of foam is positioned above the second piece of foam;
- b. cutting into said first foam structure one or more components and/or a shape;
- c. forming at least a second foam structure;
- d. adjoining the first foam structure to the at least second foam structure;
- e. coating said adjoined foam structure with at least one layer of reinforcing fiber and resin securing said first piece of foam and said second piece of foam together;
- and
- f. cutting at least one C-channel into said adjoined foam structure 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.
