Halekai is a luxurious, semi-custom sailing yacht, designed by John G. Alden, Inc. and built in Portsmouth, RI to the rigorous standards of American Bureau of Shipping-A1 offshore certification. She’s a proven world cruiser, having earned the rare honor of completing a circumnavigation. Alden Yachts is a renowned top of the line yacht builder since 1909, known for rugged construction, superior joinery, high quality equipment and speed. She was customized by her current (and only) owners for self-reliant world cruising and outfitted specifically for their ten year circumnavigation. They refer to her as the ultimate cruising boat, based on their extensive blue water experience sailing aboard their two previous boats.
“Halekai” has been meticulously maintained and constantly upgraded to the highest standards. The dark green hull was awl-gripped and the diesel engine was rebuilt during a $50,000 refit in 2011/12. A complete electronic refit was done in 2019. The layout consists of a large chain locker/storage compartment with watertight door, forward guest stateroom with head/shower, main salon, nav station, walk-in workshop, walk-through galley, and aft master stateroom with head/shower.
Due to her partially enclosed center cockpit from which they can set and adjust the roller-furled sails, they “never needed foul weather gear in 120,000 miles of sailing.
YOU DON’T WANT TO MISS THIS BOAT! She’s the perfect world cruiser for a couple or family, and she has the experience and pedigree to prove it. Her stunning lines and graceful curves speak to her performance at sea, and the modifications that her owners have made to her have made her a self-contained “island” where you can be fully self sufficient.
Basically, all the work has been done for you to make this boat the ideal world cruiser. All you have to do is provision and set sail.
Note that third cabin has been customized into full workshop.

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)
Alden design #1180x. (ALDEN 50/52/54). Of this series, the ALDEN 50 was the first boat planned and the last built.
Not to be confused with another ALDEN 50 built by Cheoy Lee, a much earlier design.
See ALDEN 54 (1985).
