Our unsinkable, indestructible, maintenance-free Whalys are an affordable alternative to more expensive boats on the market today. Crafted entirely of high density polyethylene (HDP), these spacious, double-walled boats are rugged and puncture-proof --stronger, safer, and more durable than fiberglass, aluminum, and inflatable boats. Their better performance offers more control for rescue teams, work crews, and boating enthusiasts. And they're virtually maintenance-free. Plenty of boating fun at very affordable prices.
