So, when I forward water landing, there is a strong side bar in my text that urges landing away from waves, having float skis, having inflated main spar, having modified clothes, having modified hook-in, having survival gear, and having means to set the wing to sailing-on-water format.
Additionally, my text in forum has shown the deliberate arrangement where the HG pilot aims positively to drop off flight prior to contact with water; pilot drops out into water and lets wing glider to water on its own. Then the pilot could swim to the wing (plan clothing and tools appropriate to the challenges). Upon reaching the wing, begin to arrange the parts to form sailboat. Parts of wing are to be waterproof; tubes are to be so filled so they may not take up water. Consider dropping out of a wing; let the dropping out trigger an immediate morphing of the wing to become useful boat. An adventure await for those who will master water-HG and X-Ocean HG.
For X-Ocean kite-system-assisted hang gliding, the wing and all parts used would receive careful purpose-directed design engineering.
