SK 700 Information, Review, Specs

While many vessels of this era were purely utilitarian, the SK 700 gained a following for its balance of traditional aesthetics and fiberglass durability. It remains a common sight in European marinas, often identified by its steady, rhythmic engine note and the heavy use of mahogany and teak trim in the cockpit.

Sailing Performance & Handling

The SK 700 is a pure displacement hull, and as such, it does not utilize a sailing rig or carry sailing-specific technical ratios. Its performance is instead dictated by its waterline length and hull efficiency. Most models were originally equipped with small, reliable marine diesels, typically ranging from 10hp to 25hp, with Bukh and Volvo Penta being the most common installations.

Under power, the SK 700 cruises comfortably at 5 to 6 knots. Due to its rounded displacement hull, the boat tracks with remarkable stability in a head sea, though it can exhibit a predictable "snipa" roll when taking waves on the beam. The deep rudder provides authoritative steering at cruising speeds, but like most single-screw, shaft-driven vessels, low-speed maneuvering requires a firm understanding of prop walk, particularly when backing into tight berths. The vessel’s weight-to-length ratio ensures it is not easily bullied by windage, a common advantage of this hull type over lighter, modern planing hulls.

Interior Comfort & Variations

For a seven-meter vessel, the SK 700 offers a surprisingly functional interior layout, largely due to its generous beam and the "cockpit-living" concept favored in Scandinavia. The main cabin features a classic V-berth configuration forward, which serves as a dining area with a drop-down table that converts into a large double berth. Shelving runs along the hull sides, providing ample storage for coastal weekenders.

The living experience is centered in the cockpit, which is typically sheltered by a hardtop or a heavy-duty canvas enclosure (kaleche). In most variants, the galley is located here, tucked under the windscreen or beneath the helm seat, featuring a two-burner stove and a small sink. This layout allows the cook to remain part of the social activity while underway or at anchor. Sibling models built on the same hull lineage include the slightly larger SK 800 and the SK 950, which offer increased headroom and dedicated heads (toilet) compartments that are often more cramped or omitted in the 700 series.

Known Issues & Buyer’s Checklist

Prospective owners should pay close attention to several technical areas common to these aging Scandinavian cruisers:

1. Bukh Diesel Maintenance: Many SK 700s still carry their original Bukh engines. While these are remarkably durable, they are often raw-water cooled. A thorough inspection of the cooling jackets and exhaust elbow is required to check for internal salt-scale buildup or corrosion.
2. Window and Port Sealing: The aluminum-framed windows of the era are prone to seal failure. Check the interior woodwork for water staining or "blackening" of the mahogany, which indicates long-term leaks from the window tracks.
3. Hull-to-Deck Joint: Inspect the rubbing strake and the hull-to-deck joint for signs of separation or impact damage, as these boats were often used for rugged coastal work in rocky archipelagos.
4. Stern Gland and Cutlass Bearing: Given the shaft-drive nature of the vessel, the stern gland (packing box) should be checked for excessive dripping. An aging cutlass bearing will often manifest as a distinct vibration at specific RPM ranges.

Community & Resources

While there is no singular international owners' association, the SK 700 is well-supported by regional Scandinavian clubs. Technical data and historical brochures are frequently shared through the Danish SK-Klubben and wider motorboat forums in Denmark and Germany. For engine-specific support, the Bukh Marine Diesel archives remain a primary resource for maintenance manuals and spare parts sourcing for the original powerplants.

The Verdict

The SK 700 is an ideal choice for the traditionalist seeking a low-maintenance, fuel-efficient cruiser with timeless Scandinavian lines.
