The captain made a navigational miscalculation so this 2005 Sabre 386 rested on a shelf just outside Cameleon Harbour in British Columbia for the tide to return. As a result of this temporary grounding, seagrass entered and blocked a through-hull. Identifying details have been omitted at the request of the captain. (Photo/ Bert Vermeer)

Examples of glass filler (microspheres) and glass material (cut fibers and two fabrics) for plastics reinforcement: glass microspheres (or glass beads); diameter: about 300 µm, specific gravity: 2.5. Mineral filler mainly used to increase the stiffness of a thermoset resin and to make road safety markings; 5 mm length chopped strands of fiberglass used to reinforce thermoset resins; fibrous reinforcements for thermoset resins: two glass fabrics with different area density; fiber orientation: 0 and 90° (most common): weave pattern: taffeta (down left, area density: 550 g/m2), and 2x2 twill (down right, area density: 280 g/m2).
