The owner bought this boat in 2006
General condition and any additional information
The cow 33 is a very pretty boat, with a commodious interior, and is a quick and stable on the water.
Standard features
The Cal 33 is a unique blend of performance and comfort in an attractive package that will serve you well whether cruising or club racing with family and friends. It will satisfy owners and guests with its functional and innovative lay-out and thrill the sailor seeking spirited performance. The Cal 33 has an open feeling below with two double berths at the ends of the boat creating an unusually airy spacious feeling in this size boat. The engine compartment is beneath the companionway allowing space for a large quarter berth which is open to the main salon and features two opening ports (one outboard and one into cockpit) for ventilation The forward cabin is intended for the owner and features a large v-berth w/filler, storage under the v-berth, drawers, alcoves and shelves, This is an unusually large cabin giving the owners seclusion away from the navigation station and companionway.To starboard of the passageway leading from the salon to the owners cabin is the ships head. Which is very functional, bright,well ventilated and provides ample storage.Opposite is a large hanging locker. In the central part of the boat you will find the dining area, galley and navigation station. The dining table has a folding leaf; the chart table is of proper proportions and can be used while standing or seated on custom stool.The galley is particularly attractive because of its storage capacity. with lockers, dish bins, glass racks and counter space. There is a large ice box, double sink and propane stove.
Extra gear included
Plow anchor, danforth anchor, life jackets, Bimini frame, cruising spinnaker, GPS, dock lines,
Improvements to the hull, deck, rigging, engine, or interior
Cushions recovered eight years ago, new soul in cabin and new soul in cockpit two years ago, Hummingbird depth sounder, compass recently reconditioned,
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)
Shoal draft: 4.50’.
