Sea-Doo: Over half a century of fun on the water! In 1968, the first mass-produced, water jet-powered, sit-down personal watercraft was introduced as a Sea-Doo. Its launch propelled an industry that has produced nearly two million personal watercrafts. Since then, Sea-Doo has used industry-leading design innovation and advanced mechanic engineering to become the world's most trusted brand of personal watercraft. Thanks to the dependability of our models - more than 90% of Sea-Doo watercrafts sold in the last decade are still on the water today - you can relax and ride.
