Finnrose 45 Information, Review, Specs

Sailing Performance & Handling

The Finnrose 45 is a classic "heavy cruiser" in both definition and behavior. With a Displacement-to-Length (D/L) ratio of approximately 330, the hull provides a stable, predictable motion in heavy seas, a trait corroborated by the vessel's high Motion Comfort Ratio of over 40. This weight, combined with its long-keel-and-skeg configuration, ensures excellent tracking and a "sea-kindly" feel that minimizes fatigue for the helmsman during long passages.

However, the boat is relatively underpowered by modern standards. The Sail Area-to-Displacement (SA/Disp) ratio sits at roughly 12.8, indicating that the Finnrose 45 requires a stiff breeze to truly come alive. In light air (under 10 knots), the heavy hull produces significant drag, often necessitating the support of its inboard engine—originally specified as a 72-hp Perkins 4.236 or a similar 115-hp unit. Under sail, the masthead ketch rig allows for a versatile sail plan; the ability to fly "mizzen and jib" provides a balanced, low-center-of-effort configuration that handles gale-force conditions with remarkable composure.

Interior Comfort & Variations

Finnish yards of the 1970s were renowned for their teak joinery, and the Finnrose 45 is no exception. Most hulls were configured as deck saloons or center-cockpit cruisers, emphasizing living volume and privacy. The standard layout features three cabins and can accommodate up to eight berths. A standout feature is the owner’s aft cabin, which typically offers direct access to a private head and shower, a luxury for boats of this vintage.

The interior is characterized by significant standing headroom, reaching up to 200 cm (6’6”) in the forward sections and 190 cm in the main saloon. The "spacy" nature of the hull—with a beam of 14.5 feet—allows for a large U-shaped galley and a navigation station that can serve as a full-time office for live-aboard sailors. According to owner accounts of the sibling Finnrose 37, the fiberglass laminates in these hulls were exceptionally thick (often exceeding half an inch at the waterline), which provides both structural rigidity and excellent natural sound insulation.

Popular Mentions & Media

The most famous iteration of the Finnrose 45 is the Rhea, a modified version built in 1980–81 using the final hull produced by the yard. Rhea was completed as a sail training vessel for the Turun Sinikotkat (Turku Sea Scouts). Because the molds were allegedly later acquired by Siltala Yachts (the makers of Nauticat), some of the hull's DNA can be seen in later Finnish motorsailer designs. The vessel is occasionally discussed in Finnish maritime literature, specifically within works focusing on the history of the Turku shipyards, such as the book Neptunuksen hengessä.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Finnrose 45 with a focus on age-related systems integration:

• Deck and Core Moisture: Like many sandwich-constructed decks of the 1970s, moisture ingress around stanchions and chainplates is a common "gotcha." The wide, flat deck surfaces are prone to pooling if not properly maintained.
• Engine Service Life: Many original units were fitted with Perkins or Volvo Penta diesels that may be approaching the end of their service life. Access for a full repower can be tight depending on the specific cockpit configuration.
• Osmosis: While the hulls are thick, they were built before the widespread use of vinylester resins. A thorough hull survey for osmotic blistering is essential.
• Hydraulic Steering: Some models were equipped with early hydraulic steering systems. These require inspection for seal leaks and "play" in the helm, which can reduce the feedback felt by the helmsman.
• Standing Rigging: Given the ketch rig’s complexity, replacing the standing rigging on a 45-foot boat is a significant expense that often determines the feasibility of a purchase.

Community & Resources

Due to the rarity of the model, there is no dedicated international owner's association. However, technical information is often preserved through the Turun Sinikotkat sea scout organization in Finland. Enthusiasts of Angus Primrose designs also track these vessels through broader classic yacht forums, though documentation is often in Finnish.

The Verdict

The Finnrose 45 is a "tank" of the sailing world—a purpose-built ocean voyager for those who prioritize safety and comfort over racing performance.

Pros:

• Exceptional motion comfort and stability in heavy weather.
• High-quality Finnish craftsmanship and massive interior volume.
• Robust, overbuilt fiberglass hull construction.
• Versatile ketch rig for short-handed sailing.

Cons:

• Poor light-air performance; requires substantial wind to move.
• Extreme rarity makes finding parts and specific documentation difficult.
• Deep 6-foot draft limits access to some shallow coastal cruising grounds.
• Aging systems (original engines and plumbing) likely require significant investment.
