This Catalina 30 is a sailor’s boat through and through and has a lot of upgrades to make it perform no matter what you ask of it. Read on to learn more.
It starts with the design of the Catalina 30. The high-aspect-ratio of the keel provides greater righting motion. Additionally, high aspect ratio keels are easier to turn quickly as well as sail close-hauled. And, this Catalina 30 has a lead keel with stainless steel bolts (see pictures), which both indicate the quality of this boat.
With a waterline length of 25’, the Catalina’s displacement of 10,200 lbs is slightly above average for modern cruiser-racers, which is positive because it gives the boat greater stability.
You combine the high aspect ratios with above-average displacement and you get a sailboat that has the best of both worlds, speed, and responsiveness, as well as stability in foul weather. This performance is what makes the Catalina 30 one of the most successful production sailing yachts in history with more than 6000 sold.
However, there is one key design flaw for the Catalina 30 that the current owner has fixed on this boat, making it unique among Catalina 30s. Specifically, the engine is vulnerable to being back flooded with seawater going up the exhaust due to a following wave or heeling too much. The owner completely redid the exhaust system including putting in a $600 custom exhaust pipe to prevent this. The owner also put in two bilge pumps to have redundancy for this important piece of equipment.
Beyond its performance and the upgrades the owner did to the systems, the cockpit is large and comfortable for a 30’ sailboat and easily accommodates the helmsman at the wheel plus four companions.
Down below, the interior of the Catalina 30 is roomy, and quite well laid out, The forward cabin has large V-berths which form a large double when the included board and cushion connect the two sides.
The head is quite comfortable with a toilet, shower, sink, and mirror. There is good storage space for clothes in a hanging locker and drawers opposite the head.
The main cabin is large and comfortable for a 30’ boat. There is an L-shaped dining area to port and a straight settee to starboard. This Catalina has two tables that can be used in the dining area, a small table for two people, and a larger table for 5 that folds up against the forward bulkhead when not in use (see pictures of both).
In the galley, there is an icebox, refrigerator, stove, sink, and microwave.
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)
With more than 6000 sold, the Catalina 30 is one of the most successful production sailing yachts in history.
During the long production run of this basic model there were a great number of variations with standard and tall rig configurations, each with a bowsprit option, and also including shoal, wing and deep fin keels.
A MK II version began around hull# 3300 (1986).(T-shaped cockpit is the most notable change)
The Mark III (1994) (walk-thru transom with boarding/swim platform standard though offered as an option on earlier models.)
Aux. power:
The early Yanmar, Universal 5411 and Atomic-4 engines were phased out in favor of the 3-cylinder Universal M-25 diesels during the middle 80s.
