Seller's Description

Go to Sailing Texas classifieds for current sailboats for sale Catalina 30, 1985 sailboat for sale This was my father’s boat who recently passed. He was the second owner and bought it in 1987. It’s been on Lake Washington the entire time except for maybe 5 trips to the islands. Very little use but will need its nooks and crannies cleaned. Otherwise it’s a great boat. The good: 560 hours on the Universal 3 cylinder diesel engine. Starts right up and runs smooth. No smoke on startup or running. Headsails are pristine. They have been kept in dry heated storage at my parents house. We didn’t sail much. There is a North mylar genoa and a couple other dacron headsails, I’ll inventory later this week. The main is on the boom and probably needs cleaning, but also hasn’t had a lot of use. Has a dodger. This was also kept at my parents house and is in good shape. All the cushions except the v-birth cushions are in excellent shape. There was a foam topper on the v-birth that apparently held moisture and destroyed the fabric on the v-birth cushions. No deck core rot or bulkhead rot. Two new batteries and a new 20 amp charger. It is in a private marina and is likely that moorage can be transferred to a new owner.

The less good:

Could use a thorough cleaning. There’s one ding-ding on the hull that will need a gel coat repair, shown in photo. Rest of hull shows no dings or damage. Switches on DC panel are fussy so must be suffering corrosion. I’ll be fixing this this week. Not everyone will be down with the alcohol stove/oven. But they are simple and safe. No roller furling. Toilet will need attention. Hasn’t been used in 20 years so it’ll need a kit or replacement. The factory hull striping is yellow-gold. My dad didn’t like it so he used striping tape to cover it over with blue. Worked really well for 25 years but is now peeling off. $14,000 obo. Located in Seattle, WA

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.


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

8.42 knots
Classic formula: 6.59 knots
Sail Area/Displacement
>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.


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.
<16: under powered
16-20: good performance
>20: high performance
>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.


Ballast / Displacement * 100

<40: less stiff, less powerful
>40: stiffer, more powerful
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.


D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
<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.


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
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
>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.


CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
<2: better suited for ocean passages
>2: better suited for coastal cruising


BMW diesel (9hp) offered as an option.
