QUIDNON has a large, flush deck, unencumbered by cabin tops, hand rails, vents and various other features that often makes sailboat decks far less useful. It can be used for lounging around in a chaise-longue or a hammock, for stacking bales of hay or cords of firewood, or for mounting various bits of equipment, such as plastic incinerators, digesters that produce gas for cooking or for running the engine, and biochar kilns. It can even be used to keep a few cages of chickens (for eggs and meat) and some small livestock (goats, for milk) tethered to the foremast. It is covered with aluminum diamond plate, for good traction, excellent wear resistance and to keep the boat cool by reflecting most of the sunlight.
The large expanse of QUIDNON's deck (measuring close to 550 square feet) is interrupted by two masts stepped in mast tabernacles, a large hatch in the center of the deck, and the dodger and cockpit aft. These elements are quite traditional; but there are also two more elements that are somewhat peculiar: there are two deck arches. They bear resemblance to boom gallows, but they are much more than that. In keeping with QUIDNON's overall design philosophy, they fulfill as many different functions as possible, to save space and to minimize costs.
