Seller's Description

Cal 34 MK III is for sale in San Pedro, CA.

Cal 34’s were conceived as a true racer-cruiser, and early promotional literature stressed her racing performance. This 1978 Cal 34 MK III is a fast sloop, cruising sailboat.

She has been refit over the last 3 years. EXTERIOR: She has new running rigging with Dyneema halyards (3), new mast hardware, brand new sails (main and 100% Genoa), Interlux topside and hull paint, new bottom job done February 2024, new sails (main and 100% Harken furled genoa), brand new Harken Vang Master boom Vang, new stainless propane BBQ, new Sunbrella Canvas and recently serviced self tailing winches.

INTERIOR: Reupholstered custom interior, new propane stove/oven, new water pump and all faucets/shower head

MECHANICAL: Rebuilt transmission and major engine tune on her Westerbeke 30, added additional oil capacity and filtration to complement her all synthetic oil reserves, , owner put approximately $35,000 in her over the last 6 years.

She is for sale with an additional blooper sail for downwind fun.

Pacific Breeze has been meticulously maintained and upgraded to make life sailing, on the hook or partying at the dock pleasurable and comfy.

She handles very well with her wheel steering and can handle 6-8 passengers with ease. We have slept up to 6 adults however 4/5 is way more comfortable.

This later Cal 34 MK III has a more conventional layout, with galley aft to port, quarter berth and chart table to starboard. The saloon of the last version has a settee to starboard, dinette to port. V-berths in the forward cabin with the head between the main cabin and forward .

She is absolutely ready for many adventures to Catalina and day sailing.

Calculations

Hull Speed
7.6 kn
Classic: 7.12 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

7.57 knots
Classic formula: 7.12 knots
Sail Area/Displacement
15.8
<16: under powered

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.
15.78
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
36.9
<40: less stiff, less 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

36.92
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
284.8
275-350: heavy

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
284.81
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
29.8
20-30: coastal cruiser

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
29.79
<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
1.8
<2.0: better suited for ocean passages

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
1.82
<2: better suited for ocean passages
>2: better suited for coastal cruising
