MP 27 Information, Review, Specs

Sailing Performance & Handling

The MP 27 is a fin-keel monohull equipped with a skeg-mounted rudder, a configuration that balances maneuverability with the directional stability required for coastal cruising. Its masthead sloop rig provides a reported sail area of approximately 36.1 square meters, resulting in a Sail Area to Displacement (SA/Disp) ratio of roughly 17.7. This indicates a boat that performs reliably in moderate breezes, though it is not a "light air" specialist.

Handling characteristics are defined by the vessel’s substantial ballast-to-displacement ratio of 41.7%. This makes the MP 27 exceptionally stiff and capable of carrying its canvas well into higher wind ranges without excessive heeling. With a Displacement/Length (D/L) ratio of 266, the boat falls into the moderate-to-heavy cruising category, providing a seakindly motion that minimizes the "hobby-horsing" often felt in lighter 27-footers. According to technical documentation maintained by the Finnish MP Boat community, the hull’s cross-laminated structure (composed of four layers of 4mm plywood) creates a rigid platform that feels much more solid underfoot than contemporary fiberglass equivalents.

Interior Comfort & Variations

Because the MP 27 was often delivered by the shipyard in a "half-finished" state, the interior configurations vary significantly between the seven hulls. Owners typically completed the fine joinery themselves, meaning some boats feature professional-grade mahogany finishes while others may be more utilitarian. Despite this, the general layout remains consistent: a cozy main cabin capable of sleeping four, a compact galley with a sink and stove, and a private head.

The use of cross-laminated wood provides natural insulation that modern fiberglass cannot match. This construction significantly reduces condensation and provides superior thermal retention, making the cabin comfortable in the cooler climates of Northern Europe. The interior volume is generous for a 27-foot boat of its vintage, benefitting from a beam of 2.76 meters. Many owners have noted that the "storm beds" or settee berths are specifically designed for offshore comfort, providing secure sleeping quarters even when the boat is heeled.

Known Issues & Buyer’s Checklist

• Hull & Coating Integrity: While the cold-molded construction is highly durable, it relies on the exterior fiber coating to remain watertight. Any deep gouges that penetrate the protective layer can lead to moisture ingress in the plywood layers. A professional moisture meter test is essential during survey.
• Varnish Maintenance: Given the extensive use of wood, particularly if the boat retains its original wooden mast, the maintenance schedule for varnish is rigorous. Neglect can quickly lead to silvering or rot in the outer veneers.
• Engine Obsolescence: Many units were originally fitted with small gasoline or early diesel engines like the Vire 12. Buyers should check if the auxiliary power has been modernized, as parts for 1970s-era Finnish engines are increasingly difficult to source.
• Custom Finish Variability: Since many interiors were owner-finished, the quality of electrical wiring and plumbing may not meet modern standards. A thorough inspection of the "behind-the-scenes" systems is required to ensure safety and compliance.

Community & Resources

The MP 27 shares its DNA with larger siblings in the Pulli fleet, most notably the MP 28, MP 30, and the larger MP 34 and 36 models. These boats were built on the same core philosophy of structural longevity, a fact evidenced by the high survival rate of the fleet. Technical support and history are primarily facilitated through the MP-veneet (MP Boats) owner association in Finland.

The Verdict

The MP 27 is a "connoisseur’s" daysailer and coastal cruiser that offers the soul of a wooden boat with the structural rigidity of a modern composite. It is best suited for sailors who appreciate traditional aesthetics and are willing to maintain a wood-based hull.

Pros

• Exceptional stiffness and stability due to a high ballast ratio.
• Superb natural insulation and lack of condensation in the cabin.
• Unique, classic IOR-inspired aesthetics.
• Extremely high build quality with a history of longevity.

Cons

• Extremely rare, making it difficult to find on the market.
• Higher maintenance requirements compared to pure fiberglass hulls.
• Performance may feel sluggish in very light winds due to displacement weight.
• Inconsistent interior quality due to owner-finishing.
