Seller's Description
Carl Alberg designed the 30 to meet the needs of the serious cruiser: there are berths for five, including a double, in the two cabins. The head is accessible behind closed doors from either cabin, and there is ample locker and storage space throughout. Her galley was recently re-designed to include more storage areas and more efficient use of space, the large top-loading icebox, And don’t forget the warmth of wood that Cape Dory builds into every one of its yachts. The 30 is no exception; from top to bottom, you’ll see plenty of evidence of Cape Dory craftsmanship.
1984 Cape Dory 30’ Cutter rigged, Perfect Bluewater, 4ft draft, classic sailboat for Island hopping the Caribbean, excellent weekend liveaboard for Culebra and Vieques. , everything works, and she is looking for a new home, sails like a dream, the engine runs great, the sails are in good shape, and she is ready to go sailing.. Safe, reliable full-keel boat for mellow sailing.
The basic hull design of Cape Dory yachts is a traditional one that has proven itself over many years of use and thousands of miles of cruising. The long keel with attached rudder hull configuration combined with a generous but not bulbous beam provides stiffness and longitudinal stability; it also provides protection for the rudder, propeller, and propeller shaft. Our sail plans are not as lofty as those used on more race-oriented designs of similar size. Instead of high aspect ratio mainsails, Cape Dory has continued with what it considers to be a more sensible cruising sail plan. This means that a smaller headsail is needed, that a family or a small crew can handle a Cape Dory, and that the stresses on the rig and boat are less than those on high aspect ratio rigged boats under identical conditions. The interior layouts of Cape Dory yachts are designed to provide comfortable accommodations. See here for more pic and info. https://www.yachtworld.com/yacht/1984-cape-dory-30c-8303049/

Calculations

6.3 kn
Classic: 6.4 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
- Sail Area/Displacement
-
15.1
<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.
- Ballast/Displacement
-
40.0
<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
- Displacement/Length
-
375.0
300-400: 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
- Comfort Ratio
-
32.9
30-40: moderate bluewater cruising 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
-
1.7
<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
