has a Cherry Interior and was built to do the Great Loop. All her antennas, arrays and domes are on custom mounts that lower to a clearance of 18’4”. She has been constantly upgraded & maintained to the highest standards and is standing tall for your inspection.

SEABIRD II is offered for sale by her original owner who took delivery in June 2004. He was involved in every aspect of her interior design resulting in a much more comfortable user friendly layout than the average 70E.

For example in the Salon the hidden TV on its custom lift was repositioned and is viewable from the recliner chairs as well as the settees. The optional Dining Room was enlarged for easier access to seat 6 in comfort & the entertainment center was modified.

In the Pilothouse the dining settee was enlarged and has access from both ends. The 3rd stateroom has two LOWER berths making cruising with 3 couples civilized. This change answers one of the major complaints about the Marlow 65C/70E series.

The Master Stateroom has a custom vanity and his & her heads with common shower between, a huge improvement without giving up the popular separate office and laundry area.

The Crew Quarters & head were enlarged & improved with easier aft deck access.

The 70E Marlow Explorer Motor Yacht SEABIRD II combines a handsome pilothouse profile with state of the art construction and a practical layout that is perfect for cruising in comfort and luxury. SEABIRD II represents one of the finest examples of this popular yacht currently available and has been professionally maintained by her original owner who now offers her for sale. She is well equipped for long range cruising and all services are up to date.

While capable of cruising at 17-18 knots SEABIRD II has been cruised the majority of her life at 9-10 knots therefore the total gallons of fuel burned by each engine is a fraction of the fuel burn at 17 knots. This should give SEABIRD II an effective engine hour equivalent of 800 to 900 hours of use or only 10% of the life of her 3406E CATS.

Yard service recently completed includes new Prop Speed and running gear antifouling, fluids and filters replaced, steering system serviced, Boot Stripe repainted and air conditioning serviced. The Bow Thruster was serviced and the 24V/48V conversion box was replaced. Recent new teak decks installed on aft deck and swim platform.

Vessel Walkthrough

Beginning on the covered teak aft deck features include a built-in Storage locker aft and hand-held remote Side-Power bow thruster and Morse engine controls. A molded FRP stairway with teak treads forward to port leads up to the boat deck and flybridge. Port and starboard aft are boarding doors with three steps on each side leading down to the large swim platform. Forward to starboard is the custom entrance to the Crew Quarters and Engine Room via a counter height molded FRP cabinet with side door and gas assisted lift-top.

Double centerline doors open to the spacious salon. The combination of satin finished Cherry interior joinery, cherry and granite counter tops, Ultra leather furniture and varnished teak & holly sole create an inviting warm ambiance. To starboard a large Hi–Lo table fronts the U-shaped custom tufted Ultra leather Settee with corner end cabinets. The storage below the end cabinets is accessed through cherry tambour doors. The storage below the settee is accessed by lifting the seat itself which has gas assists for ease and to keep it up during access. On the port side there are 2 Lazy Boy wall hugger recliner chairs. All the way forward on the port side is the granite topped buffet with built-in below counter bar sink, wine cooler, ice maker and refrigerator.

Forward to starboard is the Dining Room area with Cherry table and 6 matching chairs with Ultra leather seating surfaces. This area also features a large buffet cabinet forward with above counter port and starboard storage behind louvered doors and a center display area with glass shelves behind Cherry framed glass doors. Below counter height are 12 drawers for storing linen, flatware and whatever else you desire. The dining area is separated from the salon by a custom counter height cabinet which houses the Sony 42’ flat screen TV which rises on a custom lift for easy viewing from the settee or the chairs. By doing this the salon is much roomier since the port side is not taken up by the usual protruding over-sized TV and entertainment center you find on most Marlows. This allows a more social and conversational arrangement in the salon when not watching TV.

Three steps up from the salon leads to the galley and pilothouse. The starboard side open gourmet galley is truly a chef’s delight with granite counters, abundant storage, under counter Sub-Zero refrigeration and freezers plus top of the line appliances including a large Panasonic Microwave/Convection oven behind louvered doors below the 4 burner smooth cook top. The Fischer Paykel drawer style Dishwasher is under counter to the left of the Franke double sink with Grohe fixture and separate drinking water fixture. There is an additional microwave/convection oven in the aft over counter cabinets. The trash compactor faces forward outboard of the sink just inside the starboard PH door along with additional storage drawers. The port side entry door and floating teak stairway to the flybridge is directly across from the galley. The helm and settee was custom designed and built for the owner. It features to port and elevated one step an over-sized built-in angled U-Settee and slide out teak table with fold-down leaf. To starboard the offset lower helm station with Ultra leather Stidd helm chair offers excellent sight lines and comfort for running in inclement weather. By moving the helm slightly to starboard the settee was enlarged and has access from both ends solving one of the most criticized issues of the Marlow helm area. All navigation electronics and instruments are within easy sight and reach of the helmsman. The starboard side entry door is directly next to the helm.

A curved stairwell on the forward, starboard side of the pilothouse leads down to the stateroom deck and features a recessed handrail. To port is another custom feature, the guest stateroom with two lower berths and nightstand between rather than the typical upper/lower berth arrangement found in most all Marlows of this size. This answers another major complaint about the Marlow 65C/70E series. A cedar lined hanging locker is opposite the entry door and storage drawers are under the berths. An ensuite bath with shower, Corian counter, under-mount sink, Grohe Nickle & Gold fixtures and VacuFlush head is just forward. It features louvered cabinet doors finished in the Herreshoff style adding a bit of maritime elegance.

The forward VIP stateroom features a King centerline berth and excellent storage. There are two cedar lined hanging lockers, port and starboard as well as under berth storage drawers and overhead storage lockers. Two overhead Manship hatches with screens provide natural light and ventilation. The ensuite bath with teak framed Plexiglas stall shower is accessed from the stateroom or companionway allowing it to used as a day head. It features a VacuFlush head, Corian counters with under-mount sink, an opening port with screen and Grohe Nickle & Gold fixtures. The louvered cabinet doors are finished in the Herreshoff style again adding a bit of panache.

The Master stateroom is at the aft end of the companionway down one step and below the pilothouse, the quietest and smoothest riding spot in the boat. It features a king berth with drawers below and storage in various cabinets and cedar lined hanging lockers. There is also hidden storage and a safe underneath the berth easily accessed by lifting the gas assisted mattress platform. The custom Lift-top Vanity with make-up compartment storage and mirror beneath the top sits opposite the berth between the doors leading to the custom his and her heads with shower between, all features not found on other Marlow Explorer 65C/70E series yachts. The laundry and ample office area with custom level sole are down two steps and aft with additional storage.

As mentioned previously the Crew Quarters and Engine Room are accessed from the aft deck. Port and starboard berths flank the center door to the full standing height head with shower. There is storage outboard behind louvered doors. The engine room is accessed forward through a watertight door with viewing port. The engine room provides full stand up head room and excellent access to all systems and machinery and features a Sea-Chest for all incoming raw water keeping thru-hull openings to a minimum.

The Flybridge and Boat Deck are accessed either from the aft deck or the pilothouse. Forward, centerline is the helm station with twin Stidd chairs offering excellent visibility and access to the full electronics array. The entire flybridge area is protected from the elements by an FRP hardtop. The radar and steaming/anchor light are on a hinged platform that pivots down and the Sat Domes are mounted the same way to allow all antennas etc. to lower below the 18’4” height of the hardtop. This design was created to allow the yacht to cruise the Great Loop without have to remove the hardtop and the conversion can be accomplished in less than 30 minutes. Aft of the helm is a large semi-circle settee with twin fiberglass tables on pedestals. There is a break in the center of the settee for access to the Boat Deck and entertainment area. On the port side is a fiberglass cabinet housing a refrigerator/ice maker. On the starboard side is the cabinet with electric grill and wet bar plus storage beneath. The tender is mounted athwart ship all the way aft on the boat deck. The fully hydraulic davit is stepped to starboard and stows starboard to port just forward of the tender. The boat deck perimeter port & starboard is protected by an over-sized custom oval stainless steel safety rail. All the stainless safety rails on the boat are the same over-sized custom oval shape.

Hull and Construction

Flag Blue Hull

Marlow Yachts use the most modern materials and construction techniques including stacked resin infusion, DuPont Kevlar, Vinyl Ester and epoxy resins with high density core materials, and engineered fabrics resulting in a hull, deck & superstructure with more strength and less weight than possible with conventional methods.

Marlows composite construction techniques utilizing a Core-Cell foam core and only 3 major molds make for a lighter, stronger, quieter boat with less seams for potential leaks. While the foundation is a modified V form, Marlow utilizes proprietary "Velocijet Strut Keel" technology. This system uses twin strut keels that surround the propeller shafts in hydrodynamic fairings resulting in improved efficiency, tracking and stability especially in following seas. They also offer running gear protection, while modest propeller pockets keep draft to just 4 feet, 5 inches.
