very fast and ready to go - this boat has been well maintained and is equally happy daysailing or racing. Great example of a light west coast design from Nelson Marek.
Equipment: full racing sails cruising sails cushions, head, sink, cooler, repowered with YANMAR diesel in 2014 which makes this boat like new.
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)
The Santana 30-30 was designed to the MORC rule.
This version, the SANTANA 30-30PC = (Performance Cruiser). About 40 produced.
An updated PCII version featured the following:
Yanmar Diesel Engine.
Chainplates were moved outboard to allow the #3 jib to be sheeted inside the shrouds.
Interior has lower settee to allow for better headroom.
Angle brackets were added to reinforce the bulkheads.
The Grand Prix Racing edition referred to as the GP was introduced in 1983.
(See: SANTANA 30-30GP)
This model had a lighter deck. Ballast 2435 lbs., displacement 6000 lbs.
40 of these were built.
All boats built after 1985 have elliptical keels and rudders.
All versions were delivered with the same rig.
Other variations:
Some boats were delivered with an open transom.
