Alberg 30 Hull # 445 LOA: 30’ 3” Beam: 8’ 9” Draft 4’ 3” Displ. 9,000 lbs. Sail Area: Working 410 sq.ft. /w Genoa 540 sq.ft.
Tangaroa, like all Alberg 30’s, is a solidly built boat of classic design with long overhangs, full keel and a protected rudder/prop. It has a reputation for being well balanced and forgiving to sail. As conditions deteriorate, her seaworthiness starts to shine as she slices through the waves. She is well suited for heaving-to/laying haul without complications. A true Bluewater boat.
Tangaroa has seen only fresh water, having spent her entire time in the Great Lakes. She has been on the hard for the past 16yrs. and will need some cosmetic work and delayed maintenance, including an engine rebuild.
Equipment: Engine: Atomic 4 w/ several repair/shop manuals

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)
Similar to, and alleged predecessor to the ALBERG 30. Local to the SF Bay Area (USA). More information has been promised.
