The MP 27 Sailboat

The plywood hulled MP 27 sailboat was designed by Matti 'Masi' Pulli (hence 'MP') and built in Finland in 1973 and 1974. There's no doubt that 'Masi' designed a very pretty sailboat with the MP 27.

Published Design Ratios for the MP 27

Sail Area/Displacement Ratio: 17.7

  • Less 16 would be considered under-powered;
  • 16 to 20 would indicate reasonably good performance;
  • Over 20 suggests relatively high performance.

Displacement/Length Ratio: 266

  • Under 100: Ultralight
  • 100 to 200: Light
  • 200 to 275: Moderate
  • 275 to 350: Heavy
  • Over 350: Ultraheavy

Ballast/Displacement Ratio: 41.7

  • Under 40: less stiff, less powerful
  • Over 40: stiffer, more powerful

Comfort Ratio: 22.7

  • Under 20 indicates a lightweight racing boat
  • 20 to 30 indicates a coastal cruiser
  • 30 to 40 indicates a moderate offshore cruising boat
  • 40 to 50 indicates a heavy offshore boat
  • Over 50 indicates an extremely heavy offshore boat

Capsize Screening Formula: 1.93

  • Under 2.0 (the lower the better): Better suited for ocean passages
  • Over 2.0: Less suited for ocean passages

Cruisers' Questions

Who was Matti Pulli?

Matti ‘Masi’ Pulli was a Finnish boat designer who designed over 50 models of sailboats, mostly made of wood veneer by cross-lamination. He named his boats after his initials as MP boats (the model also includes the length in feet). He was also involved in the Hollming Dock and Baltic Yachts.

Some of his other designs include:

  • MP 25: A 7.75 m sailboat built in 1982.
  • MP 27: A 8.36 m sailboat built in 1973 and 1974. It has a plywood hull and a long keel.
  • MP 28: A 8.45 m sailboat built in 1976.
  • MP 30: A 9.2 m sailboat built in 1974.
  • MP 31: A 9.45 m sailboat built in 1982.
  • MP 35/351: A 10.6 m sailboat built in 1988.

He should not be confused with another Matti Pulli, who was a Finnish Olympic ski jumping coach!

What is the MP27 like to sail?

This sailboat was designed by Matti Pulli, a Finnish naval architect who also created the popular MP 30 and MP 35 models. The MP 27 was the first Pulli designed boat to be made in serial production. Only seven of them were built by Länsivene Oy between 1973 and 1974, making them rare and sought-after by collectors and enthusiasts.

The MP 27 is a fin keel monohull with a skeg-mounted rudder. It has a masthead sloop rig with a reported sail area of 36.1 square meters. The hull is made of plywood, which gives it strength and lightness. The boat has a length overall of 8.4 meters, a waterline length of 6.8 meters, a beam of 2.8 meters and a draft of 1.4 meters. It has a displacement of 3,000 kilograms and a ballast of 1,250 kilograms, which is cast iron.

The MP 27 is a boat that can handle different sailing conditions with ease and grace. It has a high ballast-to-displacement ratio of 41.7%, which means it is stiff and stable under sail. It also has a low capsize screening formula of 1.9, which means it is less likely to capsize in rough seas. The boat has a moderate displacement-to-length ratio of 266, which means it is neither too heavy nor too light for its size. It has a comfort ratio of 22.6, which means it is suitable for coastal cruising.

The MP 27 is not only a good performer, but also a good looker. It has a classic design with elegant lines and curves. It has a spacious cockpit that can accommodate four to six people comfortably. It has a cozy cabin that can sleep four people in two separate berths. It has a galley with a sink and a stove, and a head with a toilet and a sink. It has plenty of storage space for gear and provisions.

The MP 27 is a sailboat that will appeal to recreational sailors and sailboat enthusiasts who appreciate its character and charm. It is a boat that can sail well in light airs or heavy weather, depending on the sail configuration.
