With a documented displacement of 70,547 pounds on the standard keel and 72,752 pounds on the shoal variant, it’s a heavy boat by any measure. Its design ratios, however, tell a more nuanced story than weight alone suggests.
Design and Construction
The 675 has the proportions of a modern performance cruiser rather than a ponderous passagemaker. Its length-to-beam ratio of 3.55 and displacement-to-length ratio of 140 place it among beamy, moderately loaded hulls that trade ultimate ocean-going heft for livable volume and reasonable acceleration.
The waterline measures 61 feet 3 inches within an overall length of 68 feet 7 inches, while the 19-foot 4-inch beam gives the interior its generous footprint. Two keel options are available: a T-bulb drawing 9 feet 10 inches and a shoal variant drawing 8 feet 6 inches. The shoal version adds roughly 2,200 pounds of ballast and displacement to maintain the stability curve when the fin is shortened.
Structurally, the chainplates mount directly to the hull rather than to a separate bulkhead or frame. This simpler arrangement transfers rig loads into the shell itself. A 4-inch-high bulwark runs the full length of the deck edge—a traditional safety feature rarely seen on boats with such contemporary styling.
The deck has an extraordinary 21 hatches, including the companionway, reflecting the emphasis on natural light below.
Rig and Handling
The 675 carries a fractional sloop rig with double spreaders swept aft at a 23-degree angle. This geometry supports a self-tacking jib and keeps the foretriangle compact for short-handed handling.
The split backstay opens the transom, removing the usual central obstruction aft and making access to the swim platform and cockpit simpler. The mainsheet traveler spans the cockpit sole directly ahead of the twin steering stations, allowing the crew to manage trim from the helm without crossing the working area.
All lines lead aft to the twin helms, a deck plan Cruising World credited with providing both safety and easy sailing. Sail area is 2,552 square feet, and the sail-area-to-displacement ratio is 25.02. That makes the boat moderately powered for its weight—enough to keep it moving in a typical cruising breeze without demanding a large crew.
Accommodations
Below, the 675 replaces enclosed, cabin-style planning with a loft-style interior that feels light, spacious, and airy. The builder achieved this effect not through volume alone, but with an unprecedented number of portholes, windows, and skylights. The saloon and surrounding spaces consequently feel open and connected, well suited to a boat of this size.
Cruising World noted that the design provides 30% more interior space than the previous model. Multiple interior configurations are intended to make use of that substantial increase, with each layout arranged to maximize the available volume for private or charter use.
Power and Systems
Propulsion comes from a Volvo Penta D3-150 diesel rated at 146 horsepower, a single auxiliary sized for a vessel of this displacement and beam.
Tankage matches the boat’s bluewater and charter ambitions. It carries 317 gallons of diesel and 264 gallons of water, providing the range and autonomy expected at this end of the market.
Verdict
The Hanse 675 is a large, beamy performance-cruising flagship. Judel/Vrolijk’s fractional rig and the all-aft line arrangement help make 68 feet manageable from the twin helms, while the light-filled, loft-style interior and meaningful increase in space over the previous model redefine the top of the Hanse range.
The hull and deck details—including hull-mounted chainplates, a full-length bulwark, and two keel depths—are practical rather than decorative.
Pros
- 30% more interior space than the previous Hanse model, arranged in a light-filled, loft-style layout
- Fractional rig, self-tacking jib, and all lines led aft for safe, easy short-handed sailing
- Two keel depths to suit different cruising grounds
- Generous 317-gallon fuel and 264-gallon water capacities
- Volvo Penta auxiliary rated at 146 horsepower
Cons
- Heavy displacement and a moderate SA/D of 25.02 limit light-air acceleration
- Hull-mounted chainplates concentrate rig loads in the shell rather than in a dedicated structure
