Abstract
A core for a water skimming device, such as a water ski, is formed by lining a mold with flexible top and bottom films of acrylic sheet material, followed by injecting structural foam into the mold between the films. The structural foam sets in contact with the films and is encapsulated in and bonded to them. The encapsulated core is wrapped in fibrous reinforcing material, which then is impregnated with thermosetting adhesive. The assembly of core, reinforcing material, adhesive and an outer layer is compression molded to cure the adhesive, which readily bonds the encapsulated core to the outer shell.
