The Seaton Expedition Seventy offers spectacular accommodations in an expedition-style world cruiser. If long-range voyaging in luxury is on your list of things to do, the Expedition Seventy is your boat.  With her molded beam of over 22', the Expedition Seventy offers extraordinary interior volume. The main saloon, dining area, and galley are contained in a space that is 16' wide and 28' long, giving home-like luxury—including a separate dining table seating eight—that is unheard of in a 70' boat.

The galley features professional full-size appliances and natural stone counters, plus tons of storage space.  Like all Seaton long-range voyagers, the Expedition Seventy has a big-ship wheelhouse for comfortable operation in any weather. The wheelhouse features twin Stidd chairs for captain and navigator, a full-size chart table, and a raised dinette for casual dining.

Aft of the wheelhouse, the crowning glory of the Expedition Seventy is her Sky Lounge. Tall, tempered-glass windows offer uninterrupted views of the world outside. A built-in wet bar, refrigerator, and day head make this extraordinary space the ultimate private retreat. For complete versatility, the built-in settee extends to form a double berth for occasional extra guests.  A cozy observation deck aft of the Sky Lounge offers additional seating and outdoor dining space.

Belowdecks, the accommodation deck includes a full-width owner's suite plus two guest suites. The owner's head has twin sinks, natural stone finishes throughout, and a luxurious home-size shower or spa-style tub/shower combination. The owner's stateroom features a king-size berth, and the hanging locker and bureau space necessary for permanent life afloat.  Each guest suite includes a private head with separate stall shower. A separate utility room on the accommodation deck contains a full-size washer and dryer, plus a custom built-in freezer.  (more below)

A signature feature of all Seaton expedition yachts is a spacious, well-organized engine room with full headroom, workbenches, and huge amounts of storage. On the Expedition Seventy, the engine room is 14' long and over 14' wide, with headroom of 6' 4".  Our concern for safety and comfort is exemplified on deck. Wide side decks, high bulwarks, and fully-protected exterior stairways provide remarkable on-deck security in any weather. On the main afterdeck, built-in banquette seating with a large dining table can comfortably accommodate six for outdoor dining. Close the side-deck doors, and the entire afterdeck becomes a protected extension of the interior living space.

The foredeck is large enough to carry a primary tender of up to 18', plus additional auxiliary craft such as a sailing dinghy, smaller RIB, or multiple kayaks. If exploring ashore is on your agenda, take along a couple of motorcycles, as well!  Designed with twin diesel power for the ultimate in get-home capability, the Expedition Seventy carries enough fuel to cross the Atlantic from the US to Europe at over 10 knots, while maintaining adequate fuel reserves for weather-induced delays. Cruise anywhere in the world without worrying about the next fuel stop.

With a low-maintenance exterior, twin engines, hydraulic bow and stern thrusters, and powered docking capstans forward and aft, the Expedition
Seventy is specifically engineered to be owner operated and maintained. However, an innovative hull mold allows the Expedition Seventy to be lengthened a full eight feet if professional crew is desired. The longer hull provides excellent accommodations for a captain and/cook team, while maintaining compete privacy for owners and guests.  With the longer hull, the Sky Lounge increases dramatically in size, and is larger than the main saloon of most yachts of this length.  Cruise anywhere, anytime in the Seaton Expedition Seventy.  With this yacht, the voyage is the destination!  to top
