Seller's Description
“Cairdeas” is a 1982 Catalina 30 that has been well cared for and updated.. We have spent weeks on board comfortably cruising Puget Sound and the San Juan Islands. The interior was updated (2021).The original engine was replaced with a Universal M3-20B diesel engine which is reliable and fuel efficient. The boat has a range of about 240 nautical miles between the two fuel tanks. The keel has been removed and rebedded to eliminate the common “catalina smile” problem. Zincs are current. New anchor light (2018). New exhaust lines (2018). Feathering 3-blade Maxprop (2018). Rudder replaced 2018 to the newer, more efficient design. Two Lifeline GPL-24T AGM house batteries installed in 2017 which have not ever been run below 80% of capacity. Balmar DuoCharger to charge start battery from house bank. Pronautic battery charger to charge and maintain batteries from shorepower. 65 watt solar panel with Victron MPPT 75/15 solar charge controller which keeps batteries topped off nicely. Victron battery monitor accurately shows state of charge for both house and start batteries. Furuno 7 inch chart plotter/radar/depth sonar on navpod by wheel. Dickinson Newport diesel heater in cabin. Dickinson Sea-B-Que on stern rail. Alcohol two burner stove in galley. Two fresh water tanks with pressure pump to galley and head. Salt water foot pump for galley sink. Manual Jabsco head. Custom arch behind cockpit neatly holds solar panel and Furuno radar. Roller furling, new 140% Genoa by Ballard Sails. Lazy jacks for mainsail. Inflatable dinghy.

Calculations
- Hull Speed

8.4 kn
Classic: 6.59 kn
Hull Speed
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.
Formula
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

>20: high performance
Sail Area / Displacement Ratio
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.
Formula
SA/D = SA ÷ (D ÷ 64)2/3
- SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D: Displacement in pounds.
- Ballast/Displacement
-
46.1
>40: stiffer, more powerful
Ballast / Displacement Ratio
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.
Formula
Ballast / Displacement * 100
- Displacement/Length
-
157.4
100-200: light
Displacement / Length Ratio
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.
Formula
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
- Comfort Ratio
-
12.0
<20: lightweight racing boat
Comfort Ratio
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.
Formula
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
- D: Displacement of the boat in pounds
- LWL: Waterline length in feet
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
- Capsize Screening
-
2.6
>2.0: better suited for coastal cruising
Capsize Screening Formula
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.
Formula
CSV = Beam ÷ ³√(D / 64)
- Beam: Width of boat at the widest point in feet
- D: Displacement of the boat in pounds
Notes
BMW diesel (9hp) offered as an option.
