This LIL yacht was designed to sail in the Johnstone Strait, B.C., and was shipped to its present location in Virginia Beach, VA With a handlaid solid hull and deck, it has a full keel, and includes both wheel and tiller steerage. Thrust is provided by a self tacking jib and self tracking main, backed up by a very reliable 11hp Yanmar Deisel engine with less than 100 hours plus a kicker mount. There is 5 of freeboard with brightwork, reinforced gunwale and the Pilot House with skylight to keep the captain and crew out of weather. GRUZJA can be safely sailed in the wheelhouse or with the cockpit tiller. For your convenience it can also find its destination by auto pilot. There is a windlass fitting on the bow and safety equipment galore. In the cabin is a fine wood finish, twin berth, enclosed head, kerosene heater, air conditioner, and instrumentation. The boat sits out of the water on a keel bunk and has a custom made full canvass cover to keep it protected over the winter. It is ONE of a Kind in all of North America and the only complement to this class is the Hardy 21 in the British Isles. Most other motorsailers are in The 30 50 ft. range with the accompanying selling price and restrictive adventuring into small anchorages which Gruzja can just slip into for the night.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64)2/3
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
