1986 Catalina 30 Sloop

Seller's Description

3/16/2024. Buy now before the price goes down. 1986 Catalina 30 (HID CTY4645F0686) documented I’m selling my well-loved Catalina 30. She’s fully found and operational. While total engine hours are unknown, during my ownership I have put maybe twenty hours on it annually. The engine by the way is a marinized Kubota D-850. Most parts can be bought at farmer prices from tractor dealers. The engine has no known issues, does not burn oil and has never not started. The current batteries (2) are from 2018 and 2021 respectively and have no known issues. I bought her to be a coastal cruiser (home based at Boston’s south shore). You should approach her on the same basis. Thus, I took out the non-functional mechanical refrigeration. With more insulation added, the ice box is an actual icebox. There is a newish autopilot (maybe 50 hours of use over four years). Otherwise the only nav electronic that works reliably is the depth sounder. My wet finger works fine for wind direction while also drying off my finger. Where I am, where I want to go and as a secondary depth sounder, Navionics on my tablet works well enough. She has sailed between Block Island on the one hand and mid-state downeast Maine on the other hand (though not all at once) with no issues. The sails are in fine shape, the roller furler works without a hassle and the engine starts on demand. All photos are of recent vintage and accurately reflect current conditions. Presently the boat is on the hard in North Weymouth, MA. Varnished interior, new tinned wiring inside and out. New LED bulbs in all fittings, both inside and out.

Equipment: Normal Catalina equipment, main and genoa on furler, newer canvas including bimini cover, main stack pack cover and genoa UV guard, Raymarine autopilot. New Lee asymetrical “drifter”.

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

8.42 knots
Classic formula: 6.59 knots
Sail Area/Displacement
25.2
>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.
25.17
<16: under powered
16-20: good performance
>20: high performance
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

46.13
<40: less stiff, less powerful
>40: stiffer, more powerful
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
157.41
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
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
11.95
<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
2.6
>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
2.61
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

BMW diesel (9hp) offered as an option.
