David owns a Fenn XT and his stowage solution is simple, elegant and efficient. It does require a small amount of handiwork, as shown in the photographs.
Step one: Install a hatch in the front part of the seat as shown below. A small amount of stringer material must be removed to make room for the juice bladder.
Step two: Attach a plastic saddle to the inside of the ski using stainless steel bolts - David positioned his on the left rail of the cockpit. In the photo you can see an identical saddle showing how the bladder is attached with a snap connector.
Step three: Drill a hole in the hatch cover for the juice pipe. David constructed a connector out of clear plastic positioned through a rubber grommet and sealed with Marine sealant. The rubber pipe is pushed onto either end of the connector. "It's important to ensure that the hatch cover is properly sealed," said David, "because it's mostly under water."
Step four (optional): Construct a tool to assist you in tightening the hatch cover. "I made the tool for loosening the hatch," said David, "when the hands are old, cold and tired!"
When in use, the bladder hangs down into the bottom of the hull, with the juice in the centre of the ski. This is clearly the optimum position and actually enhances stability. "Not only that," said David, "but the juice is kept cool too!"
