Design and Construction
The Guyline 95 measures 31 feet overall, with a 26.25-foot waterline and a length-to-beam ratio of 3.15. That makes her beamier than half of comparable sailboats.
She displaces 7,275 pounds and carries 2,425 pounds of lead ballast. The resulting ballast ratio is 33 percent—higher than only 14 percent of similar designs. Her displacement-length ratio of 180 places her among light racers rather than cruisers. An immersion rate of 160 kg/cm, or about 900 pounds per inch, indicates how little she sinks as weight is added.
The lead keel is a pivoting lifting swing keel. Depending on load, draft is roughly 4.3 to 4.6 feet, allowing the boat to settle into shallow marinas and venture well into inland waters. The hull and deck are solid fiberglass, and the boat has a spade rudder.
Rig and Handling
The Guyline 95 was offered with more than one rig, both fractional-sloop configurations. The sail-plan figures show a boat generously canvased for her size.
With the ISO reference sail, the sail-area-to-displacement ratio is 19.4. With a 135 percent genoa, it rises to 22.3. Those figures make her faster in light wind than 86 percent of similar designs. She also carries more rig than 69 percent of her peers, while a relative speed performance index of 79 places her ahead of 79 percent of comparable boats.
The theoretical hull speed is 6.9 knots. With a possible 18 hp Yanmar diesel, the calculated maximum speed under power is about 6.0 knots.
Halyard and sheet specifications are fully itemised for both fractional-rig options. The standard rig uses 10 mm halyards of around 33 metres, while the alternative calls for 30.8 metres. The 12 mm sheets range from 9.4 to 23.6 metres, depending on the lead.
Accommodations
Below, the Guyline 95 has six berths and headroom described as above average for the class. The beamy hull proportions provide that interior room. Combined with the berth count and standing space, they make the boat a credible weekender for a small crew despite its racing-derived displacement figures.
Performance Envelope and Safety
The capsize screening value is 2.03. Under the standard test, that figure would exclude the boat from ocean-race acceptance, placing it firmly in the coastal and inland category rather than among offshore campaigners.
The motion comfort ratio is 19.2, better than only 24 percent of similar designs. That is consistent with the light-racer classification and modest ballast ratio. These numbers describe a lively, shallow-draft coastal performer, not a heavy offshore cruiser.
The Verdict
The Guyline 95 is a specialised Finnish design that trades offshore credentials for a lifting lead swing keel and a surprisingly roomy, beamy hull. Its light-racer displacement and high sail-area ratios make it quick in light air, while the lifting keel makes shallow-water exploration easier. Six berths and good headroom extend its usefulness as a weekender.
The same racing lineage, however, brings limited motion comfort and a capsize screening value that rules out ocean racing.
Pros
- Pivoting lifting keel provides a draft of 4.3–4.6 ft for coastal and inland waters
- Beamier and more spacious than half of similar designs, with six berths
- Sail-area ratios provide light-air speed ahead of 86% of comparable boats
Cons
- Capsize screening value of 2.03 excludes ocean-race participation
- Motion comfort is better than only 24% of comparable boats
- Ballast ratio is higher than just 14% of similar designs
