The Catalina Expo 12.5 is a safe, exciting and fun cat rigged (1 sail) sailboat for the new or experienced sailor. It is very easy to rig and put away. Coming about is easy because the Hoyt boom system is higher than any other boat its size. Reefing is simple and it is unsinkable because of its flotation and it is easy to trailer (130 lb) by any vehicle.This boat is rare for its age because of its excellent condition. It looks like a new boat and never has sustained any damage. It hasn’t been sailed very often since the pandemic because hitches were rare to find for our vehicles at that time. The primary user went away to college that year thus it has been sailed even less frequently since. We are very experienced sailors who have owned a plethora of boats from small dinghies to 40 foot racer cruisers and have enjoyed this boat. It is unusually quick for its size and fun to sail. It comes with life vests, trailer with spare tire, oar, cooler and a custom cover.
Equipment: Trailer & spare tire, life vests, custom cover, cooler
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)
Features carbon fiber SmartRig® and Hoyt boom.
