HIGH LATITUDE CRUISING BOAT, CURRENTLY IN LAKE MICHIGAN OPERATING AS A CHARTER BOAT IN NORTHPORT BAY.
SV ALEKONA 47 LOA 13 BEAM 7 DRAFT
23 TONS FULL KEEL 85 HP ISUZU DIESEL
68K OBO !
STEEL KETCH BUILT AT WATERLINE YACHTS IN NEW ZEALAND - 1983, SHE’S SAILED LONG AND FAR OVER THE LAST 40 YEARS AND IS A HEAVY, STURDY VESSEL MADE FOR THE OCEAN.
Alekona is in sailing condition and is used for sunset charters multiple days a week. She has a gorgeous and well kept interior you will fall in love with. The exterior needs attention, particularly cap-rail, bulwarks, topside paint & bottom paint. Captain and owner is very busy with a photography business, property management and a toddler. Not enough time to tend to maintenance and upgrades that this vessel requires.
Equipment: Please email owner for vessel details and photo gallery

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)
Many different builders and types of contruction.
