Before the mid 1970?s boats were typically lifted with a pair of davits. These crane like structures are mounted to a piling or set in the ground above a sea wall, utilize a fore and an aft cable which are connected to lifting eyes on the watercraft. Boaters find davits difficult to use, as the distance between connecting points on the boat make them challenging for one person to operate. While davits are used today for lifting smaller watercraft in some unique situations, their position as the industry standard has been largely replaced by lifts that support the boat on bunk boards connected to a lifting platform or cradle system.
A major breakthrough in boat lift design occurred in the 1980?s. Aluminum was introduced as a structural material to replace galvanized steel. Although slightly more expensive than steel, its long-term appearance and corrosion resistance make it a superior alternative. Today, the best boat lifts are made from aluminum. It has steadily supplanted galvanized steel, as consumers have become knowledgeable enough to recognize its? superiority.
Over the last 30 years, a number of techniques for boat lifting a cradle system have been developed for marine lift applications. Hydraulic cylinders, pneumatic flotation, and wound cables have been explored in various configurations. Hydraulic boat lifts have been found to be difficult to protect from saltwater corrosion, susceptible to oil leakage, and they also are relatively expensive.
Floating boat lifts (lifting a boat with another boat) designs have experienced three major drawbacks. First, the port to starboard center of gravity of the combined system is raised significantly above water, requiring much additional width to be added to the floating lift to prevent rollover. Thus, valuable marina space is lost. Second, while the boat is elevated free of barnacles and other water contaminants, the lift remains in the water and, therefore, must be periodically cleaned. Third, the combined system is exposed to the heaving of wave and tidal action, as it floats on the surface of the water. Nevertheless floating boat lifts may be the only solution in very deep fresh water, protected from wind and wave action.
Piling or sea wall mounted cable-drawn boat lifts have become the choice in coastal waters. They lift the boat free of the water in minimal space at an affordable price. Of course, a number of ingenious cable routing and structural techniques have been developed by Imm Quality engineers. Intelligently designed, rigorously tested at our in-house test facility, field tested by over 25,000 lifts over 30 years in business and continuously refined by our IQ engineers based on feedback from our customers, Imm Quality Boat Lifts now offers the following models: vertical boat lifts, elevator boat lifts, boat house lifts, personal water craft lifts, yacht lifts and specialty boat lifts.
