Our Thoughts

The 2004 Sealine 47 represents a mature expression of British yacht design, combining the practical cruising capability of a 47-foot motor yacht with the refined interior appointments that defined Sealine's reputation during the early 2000s. Built by Sealine, a respected British builder known for thoughtful hull design and quality construction, this planing-hull yacht delivers the performance and comfort expected from a vessel in this class.

Propulsion & Performance

Twin Cummins diesel engines, each rated at 480 horsepower, power the Sealine 47 to a cruising speed of 19 knots and a maximum speed of 28 knots.

The Sealine 47 sleeps up to four guests across two cabins, including a master cabin with en-suite head. This two-cabin layout is typical of the 47-foot cruising yacht segment and works well for owner-operator use, small family cruising, or entertaining guests overnight. The interior design reflects Sealine's approach to maximizing livable space within the 14.75-foot beam, with functional cabin arrangements and adequate headroom throughout.

Hull & Seaworthiness

At 47 feet overall with a 14.75-foot beam and a 3-foot-10-inch draft, the Sealine 47 offers the shallow-draft characteristics valued by coastal cruisers while maintaining the stability and sea-keeping qualities expected from a planing-hull design.

2004 Sealine 47 Motor Yacht for Sale in Miami – Coastal Cruiser with Twin Cummins Power
Overview
The 2004 Sealine 47 represents a refined approach to mid-sized motor yacht design, combining British engineering heritage with practical cruising capability. At 47 feet in length with a 14.75-foot beam, this planing hull yacht delivers a balanced profile suited to coastal and offshore cruising. Powered by twin Cummins diesel engines rated at 480 horsepower each, the Sealine 47 achieves a cruising speed of 19 knots and a maximum speed of 28 knots, making it responsive enough for confident passage-making while efficient enough for extended cruising. Currently located in Miami , Florida, this vessel represents an established platform in the motor yacht segment, with a design lineage that emphasizes both seaworthiness and onboard comfort.
Hull Design and Performance Characteristics
The Sealine 47 employs a planing hull form, a design choice that distinguishes it from displacement-oriented cruising yachts. Planing hulls are engineered to lift and ride atop the water surface at higher speeds, reducing drag and enabling the speed performance this model delivers. The 47-foot length-to-beam ratio, combined with a draft of approximately 3 feet 10 inches, positions the yacht for operation in both open water and shallower coastal environments. This draft characteristic is particularly relevant for cruising the Bahamas , Florida Keys, and similar shallow-water destinations where deeper-draft vessels face operational constraints. The twin-engine configuration with 480 horsepower per engine provides 960 total horsepower, a power-to-weight ratio that supports both the 28-knot maximum speed and efficient cruising at 19 knots. At cruising speed, the twin Cummins diesels operate in their optimal efficiency band, balancing fuel consumption against range and comfort. The fuel capacity of 514 gallons supports extended cruising periods, allowing owners to cover significant distances without frequent refueling stops—a practical advantage for anyone planning multi-day passages or exploring distant anchorages.
Accommodation and Interior Layout
The Sealine 47 is configured as a four-guest cruising yacht with two cabin accommodations. The master cabin features an en-suite head arrangement, a standard luxury feature that provides privacy and convenience for the owner or primary guests. The second cabin provides additional sleeping capacity, allowing the yacht to support a small family or two couples for extended cruising vacations. The separation of sleeping quarters from shared living spaces is a hallmark of thoughtful yacht design, enabling guests to retire to private cabins while others remain in the salon or on deck. Water capacity of 160 gallons supports extended periods away from shore, particularly when cruising with a full complement of guests. This volume is sufficient for bathing, galley use, and general shipboard needs across several days of cruising, assuming responsible water management. The combination of fuel and water storage reflects the Sealine design philosophy: provide adequate capacity for genuine cruising while maintaining the maneuverability and performance expected of a planing hull yacht.
Helm and Vessel Control
The Sealine 47's helm layout is designed around the twin-engine, planing hull configuration. Twin diesel engines allow for independent throttle and shift control, enabling precise maneuvering in tight situations—a critical feature for docking, anchoring, and navigating congested anchorages. The planing hull's responsiveness to throttle input means that helm authority is direct and intuitive, making the yacht accessible to both experienced captains and owner-operators with moderate experience. The cruising speed of 19 knots represents a practical operating envelope where fuel efficiency remains reasonable and sea state tolerance is high. At this speed, the yacht maintains a planing attitude without excessive fuel consumption, and wave action that might be uncomfortable at higher speeds becomes manageable. This speed range is ideal for day cruising, repositioning between anchorages, and covering 100+ nautical mile passages within a single cruising day.
Exterior Design and Deck Space
Sealine's design team engineered the 47 with a focus on exterior livability and practical deck layout. The 47-foot length provides sufficient beam (14.75 feet) to create usable side decks and a functional cockpit area without the extreme beam-to-length ratios that characterize some modern designs. This proportion supports both seaworthiness in open water and the kind of comfortable deck presence that makes coastal cruising pleasurable. The exterior styling reflects early-2000s motor yacht aesthetics: clean lines, moderate sheer, and a profile that reads as purposeful rather than ostentatious. The cabin house is proportioned to provide adequate headroom and interior volume without creating a top-heavy appearance or compromising stability. For owners who value understated elegance over aggressive styling, the Sealine 47's design language remains contemporary and refined nearly two decades after its construction.
Engine Specifications and Propulsion
The twin Cummins diesel engine installation is a significant technical asset. Cummins marine diesel engines are recognized across the industry for reliability, parts availability, and service support. The 480-horsepower rating per engine reflects the Cummins QSB 5.9-liter turbocharged diesel, a proven powerplant used across numerous commercial and recreational marine applications. Twin installations provide redundancy—if one engine requires service, the yacht remains mobile on the remaining engine, a practical advantage during extended cruising or in situations where immediate haul-out is not feasible. Diesel fuel, compared to gasoline, offers superior energy density and lower volatility, making it the preferred choice for vessels spending extended time at sea. The 514-gallon fuel capacity, divided between two tanks, supports the range and endurance expected of a serious cruising platform. At typical cruising speeds and fuel consumption rates for this class, the yacht can cover 300+ nautical miles on a single fuel load, depending on sea state, weather, and operational practices.
Comfort and Cruising Capability
The Sealine 47 is engineered as a cruising yacht first and a performance platform second. The accommodation for four guests, combined with the master cabin en-suite and secondary cabin, reflects a design philosophy centered on extended-voyage comfort. Unlike center console or open-cockpit fishing boats, the Sealine 47 provides shelter, climate control potential, and the kind of interior space where guests can comfortably spend inclement weather. The 47-foot length provides sufficient interior volume for a proper galley, comfortable salon seating, and cabin privacy—amenities that distinguish cruising yachts from day-boat designs. Owners planning weekend getaways, multi-week cruising adventures, or seasonal migration (such as following favorable weather between Florida and northern waters) will find the Sealine 47's accommodation and fuel capacity aligned with those objectives.
Why This Sealine 47 Deserves Consideration
The 2004 Sealine 47 occupies a practical niche in the motor yacht market: large enough to provide genuine cruising comfort and range, yet compact enough to operate efficiently and navigate into many coastal anchorages. The twin Cummins diesel installation provides proven reliability and industry-standard support. The planing hull design delivers the speed and responsiveness that make passage-making less tedious, while the fuel capacity supports the kind of extended cruising that defines genuine yacht ownership. For buyers seeking a mid-sized motor yacht suited to coastal and regional cruising, with established British design credentials and proven diesel propulsion, the Sealine 47 represents a platform with a clear operational purpose. The 2004 build year places the yacht within the modern era of marine electronics and systems integration, yet the fundamental design remains timeless enough to appreciate rather than feel dated. Located in Miami, a major cruising hub with abundant service facilities and cruising infrastructure, this yacht is positioned for immediate deployment to the Bahamas, Florida Keys, Caribbean passages, or extended coastal cruising along the U.S. East Coast.

The master cabin is the primary stateroom with private head facilities, while the second cabin provides additional sleeping space. The yacht is designed with spacious interiors and high-quality finishes throughout, emphasizing comfort and livability for extended cruising. The layout reflects British yacht design philosophy, prioritizing functional use of space and quality materials over maximalist styling.
Is the Sealine 47 suitable for family cruising and overnight trips?
Yes, the Sealine 47 is well-suited for family cruising and overnight passages. With two cabins, a master en-suite, and accommodations for up to 4 guests, it provides comfortable sleeping arrangements for families or small groups. The 160-gallon water capacity and galley facilities support extended trips, and the 22-knot cruising speed allows families to reach coastal destinations in reasonable timeframes without excessive fuel burn. The planing hull design also means the boat will be relatively stable underway compared to displacement hulls of similar length.
What are the physical dimensions and handling characteristics of a 47-foot Sealine?
The Sealine 47 measures 47 feet in length overall with a beam of 14.75 feet and a draft of 3 feet 10 inches. These proportions give the yacht a moderate beam-to-length ratio typical of cruising motor yachts, supporting good stability while remaining narrow enough to fit most marina slips. The 3-foot-10-inch draft allows access to shallow-water anchorages and coastal areas while still providing the seaworthiness needed for open-water cruising. The planing hull design means the boat will respond to throttle input and trim adjustments, giving the helm responsive control compared to heavier displacement yachts.
What design and styling elements define the Sealine 47?
The Sealine 47 reflects the design philosophy of the Sealine Design Team, combining sleek exterior styling with innovative deck layout and interior arrangement. The yacht features the clean lines and modern proportions characteristic of British yacht builders, avoiding excessive ornamentation while maintaining visual appeal. The exterior design emphasizes functionality, with practical cockpit and deck spaces, while the interior showcases quality finishes and thoughtful use of materials. This balanced approach to design makes the Sealine 47 attractive to buyers who value understated elegance and practical European craftsmanship over flashy styling.
What is the cruising speed versus maximum speed, and how does that affect fuel consumption?
The Sealine 47 has a cruising speed of 22 knots and a maximum speed of 28 knots.

Diesel engines also provide better fuel economy than gasoline engines at cruising speeds, and they are less prone to vapor-lock or fuel degradation during storage, making them ideal for yachts that may be used seasonally or stored for periods.
What buyer profile is the 2004 Sealine 47 best suited for?
The Sealine 47 is best suited for buyers seeking a mid-sized, comfortable cruising yacht with proven reliability and quality construction. It appeals to experienced boaters who value European design, practical functionality, and the ability to cruise coastal waters for extended periods without the complexity or fuel consumption of larger yachts. It is ideal for owners who plan to use the yacht for personal cruising, entertaining small groups, or occasional overnight trips rather than commercial operations or extreme offshore work. The twin-cabin layout and spacious interiors make it attractive to families or couples who want comfortable accommodations, while the moderate size and twin-diesel configuration appeal to owners who want manageable operating costs and straightforward maintenance.
What should I know about the 2004 build year and the Sealine brand's reputation?
The 2004 Sealine 47 was built during a period when Sealine was producing well-regarded cruising yachts known for solid construction, practical design, and attention to interior quality. Sealine, a British builder, has a reputation for combining European design sensibilities with marine engineering that prioritizes longevity and functionality. A 2004 build means the yacht is nearly two decades old, so potential buyers should expect that systems, upholstery, and mechanical components may have accumulated use and may require maintenance or updates depending on service history. The planing hull design and diesel propulsion mean the basic structure and engines are typically robust and long-lived if properly maintained, making older Sealine yachts viable options for buyers comfortable with vessels that may need selective refurbishment.
