Engine has electrical or hand crank starting. The engine is in very good condition and appears almost new. The bilges under the engine are completely clean.

The batteries are recent AGM units mounted in the aft crawl space. Charging the batteries is from the engine, shore power or a 5 amp solar cell system. The solar power has proven adequate to support electrical loads at anchor without resorting to running the engine for battery charging.

Spare stowage and the electrical systems are neatly laid out and readily accessed in the crawl space beside and aft of the engine.

The Pacific Seacraft Mariah is well know as an extremely strongly built, traditional design sail boat. Described as "a ridiculously sturdy boat, with hull thicknesses seldom seen in boats twice her length."

Paul Lotus, during his solo circumnavigation in Selene, writes of surviving a blow with a semi-submerged shipping container without taking on any water. His book on the voyage is "Confessions of a Long Distance Sailor".

So very heavily built, extremely sea worthy, traditional design, stable and reliable if not necessarily fast.

The Mariah has a 31 foot hull length and is 36 feet overall with the bow sprit.

This particular Mariah was purchased as a bare hull by the current owner who then spent 15 years carefully designing and crafting the interior. His work is notable for both excellent design and craftsmanship.

The aft cockpit provides control of all the sheets as well as the tiller and the aft anchor with chain stored in a locker built in under a seat hatch. The teak grate cockpit foot well floor can be fixed in a flush raised position to make the cockpit useful as a sleeping area. Full instruments for both engine and sailing are visible in the cockpit including the autopilot and GPS displays which are on a hinged panel viewed through the open companionway hatch.

Down the beautifully sculpted teak ladder to the main saloon finds a large double berth to port and a single berth/seat with built in table to starboard. The interior is finished in varnished teak balanced with gloss white painted surfaces. A very clever finished crawl space extends aft of the engine under the cockpit to allow comfortable access to the engine, shaft and electrical systems.

Forward of the starboard berth/seat is a Dickenson oil fired heater. Ahead of that is a large double icebox capable of holding ice for 3 to 4 weeks on a charge. Across to port is the galley with 4 burner gas stove and oven plus counter and basin. Forward through a door way is the shower and head enclosed with a shower curtain. This is also the corridor to the forward compartment with a built in seat to port and a single berth to starboard. Carefully fitted storage in cupboards, drawers and nooks takes advantage of every available space.

The owner is tall and so is the headroom at over 6' 6".

Well crafted details are everywhere such as the Dorade vent controls built into the varnished teak panel headlinings or the beautifully made air duct that insulates the heater chimney from the cabin side and overhead.

Broker's Comments

The US-built Pacific Seacraft Mariah was known as the "most expensive 31 foot sailboat" when built and is probably the strongest hull of its kind made with deck thickness of 1.5 inches and the hull going from one inch at the topside to three inches at the keel. It is a traditional full keel double ender in the Colin Archer tradition and famous as a sea worthy world cruiser.

This particular example has been finished with a very high level of craftsmanship by the owner who spent 15 years building this boat and another ten living aboard with his wife. The boat appears to be in "new" condition today with a beautiful varnished teak and mahogany interior. The mast, sails and rigging are in excellent condition and ready to sail. This boat represents a great value in a small live aboard and is ready to cruise anywhere.
