Design and Construction
The hull and deck are entirely carbon fiber, with vacuum-infused carbon used for all structural elements and even the keel fin rendered in carbon. The hull is moulded in three pieces, with the side decks, aft section, and transom effectively part of the hull, a method that massively increases stiffness on such a narrow boat. Pronounced hard chines run the full length of the hull, and those chines are large enough to deliver real form stability, reducing heeling upwind while adding meaningful power when reaching and running. Computational flow dynamics were run with six different rudder sizes before the team settled on the larger of two options, which carries about 15% more area. The interior joinery is epoxy sandwich, mostly using linen fibers, which takes the edge off cabin noise compared to bare carbon. Oscar Södergren notes the structural engineering carries far larger safety margins than a pure race boat would use.
Rig and Handling
The mast sits fairly far aft, which trims the mainsail's relative size but opens a larger than usual fore triangle for a self-tacking jib, and the sail plan is built primarily around that jib. The carbon mast is keel-stepped, carries fiber shrouds, and the spreaders sweep aft by 24 degrees; maximum permissible headstay tension is five tonnes, and under 2.6 tonnes of upwind load testers saw very little forestay sag. Hydraulics serve the vang, backstays, and deflectors, with an electric traveler and toe-in adjuster for the twin rudders, all fingertip-controlled from the helm. Test sailors found all trimming and sail control manageable with only one or two crew on deck, and the boat accelerates quickly and responds sharply. Upwind in 15 knots true at 40 degrees, boat speed held at 7 to 7.5 knots with a VMG around 30% above many similar performance cruisers. With a Code 0 in 13 to 16 knots at 110 degrees, speeds ran 9 to 10 knots with bursts to 11, and the helm stayed finger-light. At 150 degrees apparent with full main and Code 0, the 43 becomes a rocket ship.
Accommodations
Below, the narrow beam and low freeboard cut interior volume below what the length might suggest, yet there is enough space for family cruising. The layout offers three double cabins, one forward and two aft, with a semi-open plan that minimizes full bulkheads and stays open to the forepeak until closed by double doors. The saloon centers on a table with bench settees, the galley sits aft to port, and the nav station faces it. Three large overhead hatches join coachroof and hull windows for light, and a well-appointed heads and shower complete the picture. Scandinavian finish work is simple, elegant, and impeccably built.
Known Issues
The low freeboard that aids performance also brings a tendency to bury the bows in a leftover swell, giving a wetter ride than wind-driven waves alone would suggest. The light 6,100 kg displacement makes the 43 proportionally heavier than a Class 40 or Fast 40+ and less prone to planing than those designs.
The Verdict
The Shogun 43 is a genuinely fast cruising yacht that translates raceboat attributes into a two-person world-cruising brief without pretending to be a volume-leading interior platform. Its carbon structure, hard-chine form stability, and remote-controlled rig make short-handed high performance realistic, while the narrow hull trades cabin space for speed and seakeeping behavior that rewards experienced hands.
Pros
- All-carbon vacuum-infused structure with exceptional stiffness for the beam
- Hard chines deliver real upwind form stability and offwind power
- Single- or two-person sail control via hydraulic and electric systems at the helm
- Upwind VMG well above comparable performance cruisers
Cons
- Low freeboard buries bows in swell and yields a wet ride
- Narrow beam and low topsides limit interior volume
- Heavier than pure race designs and slower to plane
