The Catalina 310 is a 31.1 (9.49m) cruising sailboat designed by Gerry Douglas (United States).The Wing Keel version is offered with a short keel fitted with large winglets. This configuration provides an interesting draft / low center of gravity / upwind performance trade off. She has been awarded 2000 Cruising World Boat of the Year Pocket Cruiser
Equipment: Raymarine Chart Plotter, ST 4000 autopilot,ST60 wind, Tridata, depth,speed, log, water temperature. Rolling in mast main, rolling Genoa,full canvas pilot house, Zarcor companionway doors,electric water heater,gas stove, oven,microwave oven, refrigerator,TV with DVDs player, stereo cd, radio with internal and external speakers,VHF with dual controls down below and at the helm. Reverse cycle air conditioner,cold and heat,and the very special feature of this vessel, is a Fisher Panda Generator 4.2,a $ 12,000.00 value,electric windlass,new propeller installed last year together with bottom job.This is the only Catalina 310 in the market with a generator. A Mercury outboard 3.5 with less than 20 hours since new,goes with boat. Marcelo 954 899 2322
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
