Beluga was built from weathering steel after the 2nd world war under the supervision of an old sea-captain. Conceived for arctic expeditions under extreme conditions, she carries a A1 offshore certification form the Germanic Lloyd. The hull is strengthened and shaped to rise up when crushed between ice floes. She spent many winters in high latitudes, and was trapped under ice for a whole winter off Greenland from which she emerged undamaged in the spring thaw. In the early 90’s she was run over at night by a cargo ship in the middle a single-handed crossing of the north Atlantic. She was dismasted and her original wood spars and booms were left in splinters. The hull survived unscathed and she limped across the ocean with a jury rig, to port, where the current alloy spars were installed. In 1998 she stranded on a rocky coast in Panama, with no structural damage sustained. She was then abandoned until 2001 in a remote lagoon, where she was acquired by the current owner and fully refitted, including full sandblasting, replacement of all hatches, windows. The interior was removed entirely until only the bare hull remained, and all steel was put into as-new condition. Since then there has been no new corrosion. From 2003 to 2019 she was engaged in hydrograpic surveys of Panama’s unexplored coasts, resulting in hundreds of new charts and the publication of The Panama Cruising Guide, that went on to sell over 30,000 copies. She has 5 steel watertight compartments and no angle of vanishing stability, which means she will instantly self-righten even if fully inverted. She sails well and it is possible average 7 knots and make over 160 miles a day in a good breeze.
Equipment: * 5 steel watertight compartments. * Controllable pitch propeller for ultimate efficiency. (steam for 24 hrs with less than 5 gallons) The diesel propulsion setup is the most efficient possible: The engine very slow-turning, extracting every bit of energy from every stroke. The engine has no sleeve bearings, all bearings are roller and needle bearings, minimizing friction. There is no raw water pump, since the engine is keel cooled. There is no oil pump, since the engine has no sleeve bearings, and there is no transmission and no gearbox, since the CPP propeller blades can be actively controlled, feathered or reversed while sailing. * All new rigging (2019) * All new titanium tangs, plates and bolts on mast (2019) * new stainless water and fuel tanks (2018) 4 water tanks, one fuel tank. * new spare mainsail. * raymarine autopilot * 500w solar power, victron charge controller * all solid stainless steel custom hatches. * type 555 windlass, heavy anchor tackle.
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)
