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. cutting a first recess into a first piece of foam;
- b. cutting a second recess into a second piece of foam;
- c. inserting a first portion of an alignment member into said first recess and inserting a second portion of the alignment member into said second recess wherein the first recess in the first piece of foam and the second recess in the second piece of foam are aligned upon securing said first piece of foam to said second piece of foam with the alignment member;
- d. coating at least a portion of said first piece of foam and said second piece of foam with at least one layer of reinforcing fiber and resin, securing said first piece of foam and said second piece of foam together to form the boat hull;
- and
- e. comprising 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 and are secured together via an alignment member positioned such that a first portion of the alignment member is in the first recess and a second portion of the alignment member is positioned in the second recess;
- d. at least one layer of fiber impregnated with resin, said at least one layer of fiber impregnated with resin suitable for covering at least a portion of 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 core 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 core within said at least one C-channel.
