Seller's Description

Well loved Catalina 30 for sale. Not a project boat - the long term upgrades have been completed. Hull has epoxy barrier coat. The atomic 4 engine is rebuilt and runs like a champ.

Were moving up to a bigger boat, so this is priced to sell.

Equipment: Wood trim is freshly varnished. 2020 new exhaust water muffler. New exhaust to stern with new thru hull. 2021 new sanitation hose. No stinky cabin! New water pump. 2022 new running rigging. 2022 new winter cover. 2023 new Raymarine autopilot. 2023 Newly machined prop shaft, new cutlass bearing. Rudder bushings replaced. 2024 new 150% Genoa, Raymarine i70 multifunction display, Airmar triducer, B&G anemometer. Well stocked: dishes, tools, Magna grill. Fresh flares, and fire extinguishers. VHF with remote RAM mic. LED lighting. Whisker pole, Spinnaker with ATN tacker and sock.

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.
