78 Marlow 2010 Boat for Sale

The pilothouse is impressively spacious and thoughtfully configured to maximize both comfort and functionality. Rather than a large, underutilized lower helm station, unnecessary in a command bridge design, the space has been intelligently reimagined with a generous seating area and teak table forward, creating an inviting setting for dining, relaxing, or planning passages. A compact helm station is positioned to starboard, offering a practical and efficient command position.

Aft of the dining area, the galley is seamlessly integrated and open to the salon, promoting a natural flow between living spaces. To starboard, a staircase provides convenient access to the staterooms below.

The secondary helm is designed with the owner-operator in mind, allowing the captain to remain engaged with family and guests while operating the vessel during extended offshore passages. This station is equipped with a modern Raymarine chart plotter, providing comprehensive navigation data and enhanced situational awareness in a streamlined, accessible layout.

The galley is centrally located on the main deck, positioned at the aft end of the pilothouse, which is accessed by three steps up from the salon. Thoughtfully designed, the space features an open sightline beneath the aft galley cabinetry, allowing visibility through to the salon and aft deck, enhancing the sense of openness and connection between living areas.

The countertops are finished in elegant Black Galaxy granite, adding both durability and a sophisticated visual appeal. An undermounted sink is positioned on the aft side of the counter for convenient workflow, while the U-shaped layout places a Gaggenau cooktop to starboard, complete with removable stainless steel sea rails to secure cookware underway. Below the cooktop, a matching Gaggenau oven is seamlessly integrated into the cabinetry.

Forward in the galley, Sub-Zero refrigerator and freezer drawers are conveniently located adjacent to the sink and dishwasher, providing efficient access to cold storage while maintaining a clean, organized layout. Generous cabinetry above and below the counters ensures ample storage, making the galley highly functional for both extended cruising and entertainment.

The engine room offers full stand-up headroom and is fully air-conditioned, creating a comfortable and accessible working environment. There is excellent access on all sides of the engines, allowing for straightforward inspection and maintenance.

At the forward end of the engine room, a centralized sea chest supplies seawater to the engines, generator, air-conditioning system, and all other onboard systems requiring raw water cooling. Each system is individually valved, providing convenient isolation for servicing and enhanced operational control.

A single 3,000-gallon fuel tank is positioned just forward of the engine room bulkhead, strategically located near the yacht’s center of buoyancy. This design helps maintain a consistent running angle regardless of fuel level, contributing to stable and predictable performance underway. Additionally, the fuel tank serves as an effective sound barrier, further insulating the forward living spaces from engine noise and vibration.

The cockpit features uninterrupted teak decking and a built-in seating area with an accompanying table, creating a comfortable and inviting outdoor living space. An extended boat deck provides full overhead coverage, offering excellent protection from both sun and rain while enhancing the usability of the cockpit in a variety of conditions.

Double doors from the salon open directly into the cockpit, allowing the two spaces to seamlessly merge into one expansive entertaining area, ideal for indoor-outdoor living and social gatherings. Aft, transom doors provide access to an oversized swim platform, which in turn connects to a transom entry leading to the engine room and dedicated crew quarters, ensuring efficient and private access to technical spaces.

The yacht is also equipped with a fixed docking station that has been upgraded with a Dockmate wireless control system, allowing for precise and convenient maneuvering of the engines and thrusters from the deck.

This yacht is constructed using advanced materials and modern building techniques that deliver exceptional strength while maintaining a lighter overall displacement than traditionally built vessels. The incorporation of Kevlar, modified epoxy resins, and high-density core materials results in a hull that is stronger than many heavier counterparts, yet significantly more efficient.

Throughout the yacht, honeycomb and structural foam cores are utilized in counters, cabinetry, and soles, contributing to both durability and weight reduction without compromising structural integrity or finish quality.

While performance is impressive, the benefits extend well beyond speed. The reduced weight enhances fuel efficiency and range, allowing for extended cruising with lower operating costs, an advantage that is especially valuable for long-distance passagemaking and time spent offshore.
