The new owner of this pursuit requested a better enclosure than what was currently on it.  We fabricated it with Makrolon AR2 Polycarbonate windows, Solarfix PTFE Thread and Sunbrella Marine Fabric.  The owner requested a sliding doorway, and due to the limited room where the factory installed track was, instead of second hard mounted track, a sewable track was built into the upper zipper flap.  This worked out well and the owner was very pleased.   The lower canvas on the doorway also rolls up and zips to itself to keep from flapping when under way.
