Design and Construction
Sundén’s mid-1970s design combines a solid fiberglass hull and deck with an iron keel. It was offered with different keel alternatives, allowing owners to trade draft for access to shallower berths.
The standard long-keel version draws about 5.4 to 5.7 feet, depending on load. A shoaler long-keel option reduces draft to roughly 4.1 to 4.4 feet, allowing the boat to enter even shallow marinas.
Her proportions are notably conservative. With a length-to-beam ratio of 3.61, she is slimmer than 98 percent of comparable designs. A displacement-length ratio of 307 places her squarely among heavy cruisers, while her 46 percent ballast ratio is higher than that of 76 percent of similar sailboats. That combination favors steadiness rather than acceleration.
Rig and Sail Plan
The Marieholm 26 has a fractional rig. Her reference sail area produces a sail area-to-displacement ratio of 13.4, rising to 15.3 with a 135 percent genoa. By that measure, she carries more rig than 8% of all similar sailboats. That puts her among the significantly underrigged boats in her class, and she is faster than only 18 percent of her peers in light wind.
Halyard and sheet requirements are modest. The mainsail and headsail halyards are about 23.2 meters long at 8 mm, while jib and genoa sheets are about 7.9 meters at 10 mm. The mainsheet is about 19.9 meters. These sizes and lengths are all within easy reach of a weekend sailor’s standard inventory.
Performance and Motion at Sea
The Marieholm 26’s numbers describe a soft-riding, undramatic boat. Her Motion Comfort Ratio ranges from 27.7 to 29.2 and is said to be more comfortable than 95% of all similar sailboat designs. An immersion rate near 507 pounds per inch means she sits heavily and stills quickly in a seaway.
The theoretical hull speed is 6.0 knots, while the calculated maximum speed under engine is only about 3.7 knots, consistent with her full-bodied hull. A capsize screening value of 1.61 places her within accepted offshore-racing thresholds, although the source’s commentary on that point is cut short.
Accommodations and Intended Use
The Marieholm 26’s modest beam restricts interior volume compared with beamier boats of the same era. In return, her heavy-displacement hull, long-keel steadiness, and strong comfort-ratio showing suit a boat conceived for sheltered-water cruising and estuary hopping rather than racing. The shoal-keel option extends that range into quiet coves and tight Scandinavian marinas.
The Verdict
The Marieholm 26 is a conservative, comfort-led Nordic cruiser. Her slender beam, heavy ballast, and full hull deliver a remarkably quiet motion for a boat of her size, but the trade-off is clear: limited light-air speed and an underpowered rig that asks the crew to work harder than a modern, overcanvased design would.
She best suits sailors who value predictable handling and shallow-water access more than sparkling performance.
Pros
- Exceptional motion comfort compared with peer designs
- Shoal-keel option opens up shallow marinas and anchorages
- Heavy ballast ratio and full hull favor stability and seakeeping
Cons
- Significantly underrigged and sluggish in light wind compared with most similar boats
- Low maximum speed under engine limits motoring range and urgency
- Modest beam restricts interior volume compared with beamier contemporaries
