AMAROO, Hallberg-Rassy 41, is a famous, very safe, comfortable long-distance cruising yacht with superior layout. One of the most known sailyacht manufacturers for Open Ocean and blue water yachts in the world. AMAROO was our beloved, comfortable and save home for 10 years. Build in 1977, famous for thick glasfiber hull. Two stateroom vessel, V-berth cabin forward and a comfortable private aft-cabin with 2 large single berths w. direct access to the cockpit. Spacious salon with a 6 ft.6” headroom. Perfect offshore galley, nav-station, workbench, 1 marine head. Holding tank. Cockpit with hard dodger. Amazing storage. Ballast is internal to the keel, no keel bolts or seal. The rudder is supported by a skeg which is integral with the hull. Hull is solid fiberglass hand-laid up with substantial structural reinforcement. Hull to deck joinery is solid fiberglass reinforced with resin and stainless-steel fasteners. Maintained with care.Last bottom job Jan. 2019, NO blisters. No leakage evidence. Teak decks fair, need some work. For more information and pictures, pls. send us an e-mail.

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)
