This is the fifth installment in a series on the design and execution of oceAnco’s latest superyacht.

The design evolution of oceAnco’s Y702 includes a traffic flow that departs from conventional execution, says designer Dan Lenard. Entry to a yacht is usually starboard amidships, on the main deck into a foyer or from the stern, either by passerelle or over the swim step, and up transom stairs.

The stern platform is always an option, yet aboard Y702 the traditional starboard amidships entry will be retained, with a difference. Naturally there will be the traditional amidships main-deck gangway. A more dramatic and logistically preferred scenario is to have guests enter a large open foyer on the lower deck. A door on the starboard side will lower to provide six square meters of dockage for the tender and to handle luggage and other gear. "It keeps initial traffic flow within the necessary areas, not requiring traversing of neutral spaces to obtain access," says Lenard. (Click image to enlarge)

From there, vertical movement is by elevator or the stairs to the main-deck suites. The main staircase, which encircles the elevator, and the crew stairs are located back-to-back in the vertical corridor. Seamlessly and privately connecting all four decks, neither intrudes either visually or physically on the other. The crew stairs open onto service spaces on three decks: a serving pantry, a skylounge galley and a foyer abaft the bridge. The main staircase opens onto neutral spaces, as does the elevator, permitting access to the staterooms, salon and other common areas.

"Separation between guests, crew and vessel operations is critical. It permits the crewmembers to conduct their business without interfering with the passengers," says Eel Kant, oceAnco’s managing director.

This separation was achieved by oceAnco developing a vertical "communication duct" comprising the staircases, dumbwaiters, elevators, guest and crew lobbies, and vertical penetrations for the major air-conditioning and electrical installations that codify into one central fire-zone layout. "It’s function, safety and simplicity supported by extensive engineering," says Kant.
