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.

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
