The Catalina 310 is a well-regarded sailboat known for its combination of performance, comfort, and ease of handling, making it a popular choice among cruising enthusiasts. Designed by the renowned naval architect Frank Butler and produced by Catalina Yachts, the 310 was introduced in the late 1990s and has since gained a reputation as a capable cruiser for both novice and experienced sailors.
Zorra Marina measures 31 feet in length with a beam of about 10.5 feet, providing a stable platform for cruising. The relatively shallow draft of around 4.5 feet allows for access to shallower waters, making it versatile for various cruising grounds.
The interior is designed with comfort and functionality in mind. It typically features a spacious salon with ample headroom, a well-equipped galley, and a comfortable dining area that can accommodate several people. . The use of quality materials and thoughtful design elements enhances the overall cruising experience.
These boat are known for their balanced sailing performance, making it suitable for a variety of wind conditions. The rigging and sail plan are designed for easy handling, which is particularly appealing to those who may be single-handed sailing or cruising with a small crew. Its wide beam contributes to stability and a comfortable ride, whether on a leisurely day sail or a longer passage.
One of the standout features of the Catalina 310 is its storage capacity. The boat offers ample storage both below decks and in the cockpit, making it easier for cruisers to carry provisions and gear for extended voyages. Constructed with a solid fiberglass hull, the boat is designed to withstand the rigors of coastal and offshore sailing.

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)
Wing Keel draft: 4.83’/1.47m
