About Us  1981 - McCulloh Contracted by US Air Force to Build a Winchboat
In 1981, Mark McCulloh executed a contract with the US Air Force at Turkey Point in Homestead, Florida to convert an existing tow vessel into a Winchboat for testing and evaluation. The Winchboat would replace the existing motorized platform providing a more efficient training operation. To date, the Military still conducts water training using McCulloh’s Winchboat invention at the Naval Air Station in Pensacola, Florida.

In 1981, McCulloh predicted a sharp rise in commercial parasail accidents using the body harness after fully understanding the lack of evacuation from the body harness by the increase in commercial parasail accidents along with data supporting the water survival training program for military to escape from a runaway parasail in emergency water landings. The harness by design is not easy evacuate during an emergency water landing. As expressed by the military, every parasailor should undergo a rigorous water survival training program. Considering that stack holders will never be implement this voluntarily, McCulloh chose to proceed with the development of alternative safety equipment. The first design was a Quick Release System similar to what is used in skydiving to eject the main parachute and deploy the reserve. In a parasail application, the parasailor could be instructed to pull a rip cord to release of the parasail from the harness in the event of a emergency water landing. Their were numerous complications with that concept and it never left the drawing board.
In 1983, Mark McCulloh designed a “Buoyant Aerial Gondola” that did not require: a) special training; or b) seat belt restraints or straps. The most important feature was the parasail release clips that automatically disconnected the parasail canopy from the structure connecting points, when the overhead support tow bar rotated forward after a emergency water landing. Further testing of the Buoyant Aerial Gondola we discovered that the release mechanism did not always work, and the overhead support tow bar “roll cage” did not always fall forward during water landings. The production of the first Buoyant Aerial Gondola was halted, and it was back to the drawing board.
About Us  1983 - The First Outboard Powered Winchboat w/ Concept Buoyant Gondola
1983, McCulloh's next vision was a futuristic Winchboat with bolt-on outboard motors, and a portable self-contained parasail launch and recovery system along with a futuristic Buoyant Aerial Gondola design.
About Us  1983 -  The world’s first Portable Launch and Recovery System (PLRS).
In 1984, McCulloh took the first step in testing the worlds first Portable Launch and Recovery System (PLRS). The PLRS comprised of a winch system, automatic canopy launching power mast, all of which was powered by a built-in 16hp diesel engine that could transform a standard boat into a winchboat.
About Us  1984 -  The world’s first Outboard Powered Winchboat Working Prototype
In 1984, McCulloh negotiated a deal the Johnson Outboards to provide modified engines that included custom transom brackets and external intake air ducts as promotional consideration to test their sea drive concept.
About Us  1984 - McCulloh AutoWinch System w/ Backup Motor
In 1984, McCulloh designed the worlds first automatic release winch system. The concept was to allow the forward wind force to release the towline automatically based via hydraulic braking vs. throttle control position. This design provided a fail- safe launch on every flight. How does it work ? When the parasail canopy and parasailor were ready to launch, the operator just shifted the winch control lever in full reverse position. Then accelerated the Winchboat. The increased speed created line load/resistance that activated the winch and released the towline automatically; similar to the drag on a fishing reel.
About Us  1984 - First Outboard Powered Winchboat SeaTrial with Buoyant Aerial Gondola
In 1984, Mark McCulloh testing his new outboard powered prototype Winchboat together with the Buoyant Aerial Gondola. The Winchboat worked perfect. However, the Buoyant Aerial Gondola still did not perform as expected.
About Us  1984 Test Flight of new Aerial Recliner  “Gondola” Passenger Support
In late 1984, McCulloh redesigned the Buoyant Aerial Gondola and named it the Aerial Recliner “Gondola". The proof-of-concept design streamlined the massive structure of the " Buoyant Aerial Gondola " and provided some additional safety features as follows: Passengers semi-reclined for additional support and comfort Eliminated the need to use the parasail release clips like in the Floating Harness. Used a lower towing point on the tow vessel that increased vessel stability in high winds and rough seas while the parasail was in flight. Allowed for easy evacuation with less obstruction during water landings.
