Personal Watercraft SMC Hull Repair Video Released

The hulls of most personal watercraft, like this Yamaha WaveRunner, are constructed from SMC, or Sheet Molding Compound. This rigid, glass-reinforced material is tough and strong, but it can break, as in this case when a teenager rammed it into a dock.

Sheet Molding Compound is like a mass-manufactured form of fiberglass. It is a thermoset material made of a heat-setting polyester resin with glass fiber reinforcement. It’s a very rigid material that is smooth on both sides. You can identify it because the substrate is white and has glass fibers in the damaged area. This video will show you the repair process for SMC personal watercraft hulls.
