1 Sealine Sc47 for Sale

Sealine SC47 Specifications

The SC47's beam of 4.48 m (14 ft 8 in) was the widest in its size class — a deliberate choice that gave the boat exceptional stability at rest, generous interior volume for its length, and a “big boat feel” that belied the 47-foot hull. By adopting pod drives instead of conventional shafts, and eliminating the traditional tender garage, the designers were able to maximise both cockpit and cabin volume within that wide beam.

The shallow 1.12 m (3 ft 8 in) draft is a significant practical advantage, giving access to anchorages and harbours that deeper-draft competitors cannot enter — particularly useful for Mediterranean island-hopping and the shallow waters of the UK's south coast estuaries. However, berth width is a consideration: the wide beam means standard 15 m marina berths can feel tight, and you may need to book a berth rated for 16 m or larger to get adequate finger-pontoon clearance.

Performance & Handling

Speed: Both engine options deliver 34–35 knots at wide-open throttle, with comfortable cruise at approximately 24 knots at 3,000 RPM. At cruise, fuel consumption is roughly 120 litres per hour (combined), giving a range of approximately 300 nautical miles from the 1,500-litre tank with a sensible reserve. Economy cruise at 18–20 knots extends range to 350–380 nm at the cost of longer passage times.

Handling: The Ocke Mannerfelt deep-vee hull provides a confident, predictable ride. Reviewers describe the SC47 as “squashing waves” through typical Solent chop, with passengers on board barely aware of choppy conditions. Pod drives (both Zeus and IPS) give exceptional low-speed manoeuvrability, and joystick docking is described by owners as “child's play.” Single-handed docking is entirely feasible even in crosswinds.

Considerations: The wide, relatively flat hull sections that provide stability and interior volume come at a cost: the SC47 can slam in heavy seas, particularly steep head-seas where a deeper-vee hull would provide a softer ride. Additionally, the boat is stern-heavy by design — engines, fuel tanks, and generator all sit aft. Adding a tender on the bathing platform exacerbates this, affecting ride quality and potentially causing porpoising at certain speeds. Owners recommend a bow thruster (standard on most examples) for close-quarters handling in strong crosswinds.

Zeus vs IPS: Both pod drive systems deliver comparable performance and joystick control. The practical difference is in the service network: Volvo Penta has a significantly broader south-coast UK dealer network than the Cummins/Zeus support chain (the Cummins dealer at Swanwick on the Solent has closed, with service now coordinated from Northampton). Several owners report that Zeus-equipped boats can suffer intermittent electronic issues. On the used market, IPS-equipped boats tend to attract a slight premium and a wider buyer pool.

Layout & Interior

Below decks, the SC47 offered a two-cabin, two-bathroom layout that prioritised space and comfort over cabin count. The full-beam master cabin aft featured a king-size berth (6 ft 6 in x 4 ft 11 in), a chaise longue, generous wardrobe storage, and an en-suite bathroom with separate shower. The forward VIP cabin matched the master in quality with its own en-suite facilities, offering a large double berth (6 ft 5 in x 4 ft 7 in). The full-beam master aft is unusual for a sportscruiser of this era — most competitors positioned the master forward with a cramped twin cabin aft.

The lower-deck saloon served double duty: a fully equipped galley to port with good counter space and storage, a dinette to starboard that seated four comfortably, and a conversion capability that turned the saloon into a third sleeping cabin. This gave the SC47 genuine flexibility — most competitors in this class offered either fixed two-cabin or fixed three-cabin layouts, not both. Interior finish throughout was light oak with satin veneers, leathers and natural linen-style fabrics in neutral tones with plum, lime green, and chocolate brown accents — a look described as “functional rather than luxurious” compared to the more traditional wood-heavy interiors of Princess and Fairline, but well-executed for the price point.

The SC47's defining interior quality was light. Extensive superstructure glazing — more than any competitor in its class — flooded every living space with natural daylight. The panoramic windows were not just aesthetic: they gave the SC47's relatively compact interior footprint a sense of openness and connection to the water that boats with more conventional superstructures could not match.

The convertible roof transformed the upper deck into the boat's primary living space. With the roof open, the helm station, sofas, and sun loungers accommodated up to 10 people in an open-air environment. With the roof closed, the same space became a fully enclosed wheelhouse-style salon with weather protection for year-round cruising. By eliminating a traditional tender garage, the designers created an expansive cockpit that is the boat's social heart — for buyers who need tender storage, a davit system or towed dinghy are the practical solutions.

SC47 Ownership: What to Expect

The SC47 is now a 13–16 year old used boat, and ownership costs reflect both the age of the platform and the quality of the original build:

• Purchase price: £180,000–280,000 depending on year, condition, engine hours, and specification. Original new price was approximately €527,600. The depreciation curve has largely flattened — boats at this age lose perhaps 3–5% per year.
• Engine servicing: Twin Cummins QSB 5.9 or Volvo D6 annual service including filters, oils, belts, and anodes runs £2,000–3,000. Pod drive service adds £1,500–2,500 annually. Zeus lower unit reseal (every ~5 years) costs £2,000–4,000.
• Fuel: At 120 litres per hour at cruise, budget £4,800–12,000 per year depending on hours (50–100 hours typical). Weekend port-hopping runs approximately £200–300 per trip.
• Marina berth: A 47-foot, 15-foot beam berth on the Solent runs £8,000–12,000 per year alongside, or £1,500–2,500 on a mid-river mooring.
• Insurance: At current values of £180,000–250,000, premiums run £1,200–2,500 per year.
• Antifouling and lift: Annual haul-out, wash, antifoul, and relaunch at £2,500–4,000 for a 47-footer.

One multi-season owner reported the boat “ran like clockwork” over four seasons with only a refrigerator replacement as the major unscheduled expense. The rule of thumb for a boat of this age and class is 10–15% of purchase price annually in total running costs.

Electronics note: Original 2009–2012 chartplotters, radar, and multifunction displays are now obsolete. Budget £5,000–15,000 for a modern electronics refit (Raymarine or Garmin MFDs, updated radar, AIS) if the previous owner has not already upgraded. This is one of the most value-adding improvements you can make to a used SC47.

How to Buy a Used Sealine SC47

Zeus vs IPS: The choice of drive system is the single most important factor on the used market. Both deliver comparable performance, but Volvo IPS boats attract a wider buyer pool and slight price premium due to the broader UK dealer network and better parts availability. Zeus-equipped boats can offer better value if the service history is complete, but the buyer pool is smaller on resale. In either case, the key factor is service history, not drive type — a well-maintained Zeus boat will outperform a neglected IPS boat.

SC47-Specific Inspection Checklist

• Convertible roof mechanism: Operate the roof multiple times, fully open and fully closed. Listen for unusual motor noises, grinding, or hesitation. Check all seals for perishing and water ingress. Inspect the track/rail mechanism for corrosion and debris. Verify both electric and manual operation work. Check the headliner for water staining, which indicates seal failure. This is the SC47's signature feature and its most complex maintenance item.
• Pod drives: Check annual service records are complete. Inspect lower units for corrosion, impact damage, and bearing play. On Zeus boats, verify electronic control systems are fault-free — run an extended sea trial (30+ minutes) to expose intermittent electronic issues. Check if lower units have been resealed (every ~5 years). On IPS boats, confirm Volvo service records and check for stored warning codes.
• Window seals and leaks: The extensive panoramic glazing means more potential points for water ingress. Inspect all porthole seals, windscreen seals, and trim tab areas. Check under cabin carpets and in bilges for signs of historic leaking.
• Gel coat: Inspect for crazing around cleats and stress points. Check below the waterline for osmotic blistering (tap test). Examine gel coat colour — fading and chalking indicate UV damage from uncovered storage.
• Engine hours: The sweet spot is 200–500 hours. Under 200 suggests light use (good, but check for issues from sitting idle). Over 800 is considered high for this type of boat. Verify oil is clean — milky oil indicates head gasket or water intrusion.

Parts and Support

Since Sealine entered administration in 2013 and was acquired by HanseYachts (Germany), parts availability requires some nuance. Mechanical components (Cummins, Volvo, Onan generators, Tecma heads) remain fully supported through the respective OEM networks — these are not Sealine-specific parts. Sealine-branded cosmetic and structural parts (gel coat colour match, interior trim, canvas, superstructure components) may require more effort to source, though the UK-based Sealine owners' community and specialist brokers maintain good knowledge of available inventory. Current-production Sealine models under HanseYachts use entirely different designs and have no parts commonality with the SC47.

Sealine SC47 vs Competitors

The SC47 competed in the 45–50 ft sportscruiser segment against established British and European rivals. On the used market, its value proposition is even stronger than when new — the absence of the brand-premium markup that Sunseeker and Princess command means buyers can access equivalent specification at a lower price point.

SC47 vs Fairline Targa 48 GT

The Fairline is the SC47's most direct competitor. The Targa 48 GT is slightly longer (15.38 m) with a narrower beam (~4.30 m), offers three fixed cabins versus the SC47's 2+1 convertible, and uses conventional Volvo shaft drives rather than pods. The Fairline has a fully enclosed hardtop (no retractable element), slightly more refined interior finish, better resale values, and a stronger dealer/service network. The SC47 counters with the convertible roof system, wider beam (more stability and interior volume), joystick docking from pod drives, and a shallower draft (1.12 m vs 1.18 m). On the used market, the Fairline commands a 10–20% premium for equivalent age and condition.

SC47 vs Princess V48

The Princess V48 was the first Princess with pod drives (Volvo IPS600) and a close contemporary. At 15.49 m and 4.11 m beam, the Princess is longer but narrower, offering two fixed cabins versus the SC47's 2+1. The Princess has a canvas roof rather than a hardtop, giving a larger opening area but less weather protection. The Princess brand commands significantly better resale values, but the SC47 offers more accommodation (the convertible third cabin), wider beam, and the unique roof system. The Princess lacks opening side windows in the cockpit — a notable omission for Mediterranean use.

SC47 vs Sunseeker Portofino 48

The Sunseeker Portofino 48 was the glamour choice in this segment, with stronger brand cachet and correspondingly higher new and used prices. The Portofino offers a retractable hardtop of its own, but a smaller opening area than the SC47's convertible roof. Interior quality is a step above the Sealine in materials and finish. On the used market, the SC47's Ocke Mannerfelt hull is widely regarded as the better-riding hull of the two, and the SC47's original Kidderminster build quality during this period — benefiting from Brunswick Corporation's investment in manufacturing processes — was considered to be among the strongest in Sealine's history.

SC47 vs Azimut 47

The Azimut 47 is a fundamentally different concept: a flybridge motor yacht rather than a sportscruiser. It prioritises interior volume and multi-level living over the open-cockpit lifestyle, with three fixed cabins, deeper draft (1.35 m), and lower performance (~32 knots). Twin Caterpillar shaft drives lack the low-speed manoeuvrability of pods. The Azimut appeals to buyers who want a floating apartment; the SC47 appeals to buyers who want a fast, versatile sportscruiser with an open-air lifestyle. Different boats for different priorities.

Best Cruising Grounds for the SC47

UK South Coast: The SC47 was designed and built in the UK and is very popular on the Solent and south coast. The 1.12 m draft allows access to shallow harbours like Chichester, Poole, and the Beaulieu River. The Mannerfelt hull handles the typical Solent chop with confidence, and the 300 nm range at cruise comfortably covers Channel crossings to France for day trips or weekend jaunts to Cherbourg, Saint-Malo, or the Channel Islands.

Mediterranean: Many SC47s are based in the Med, and the convertible roof truly comes into its own in Mediterranean sunshine. Shallow draft is excellent for Greek island hopping. The main limitation is range — 300 nm at cruise means careful fuel planning between islands, though this is adequate for the short hops typical of Dalmatian coast, Balearic, or Cycladic cruising. The relatively flat hull sections can slam in the steep afternoon chop of the Mistral or Aegean meltemi — plan passages for the morning calm.

Ideal use case: The SC47 is at its best doing 2–4 hour passages between ports, spending evenings at anchor or in a marina with the roof open, entertaining 6–10 people in the cockpit. It is a superb social boat that also offers genuine overnight capability for up to six.
