Profile: Hydro-Ventures, Inc. manufactures and installs products specifically designed for the houseboat industry. Our products are designed to fit and compliment houseboat hulls. We offer bow & stern thrusters, swim platform lifts and thruster systems. The SWL-042 swim platform lift is designed with convenience and performance in mind. The lift has two cylinders that are constructed with both ports inside the rod. Our cylinders mount from the rod end and the rear of the cylinders with the slide. This prevents the rod from being submerged when the lift is down, thereby keeping the rod seal from becoming contaminated with foreign objects.
