Seller's Description
1977 Cape Dory 27 in very good condition. Deck is dry and has almost no crazing. The original engine was a Yanmar 8 hp. The boat was re-powered under previous ownership with a 12 hp Yanmar. The engine runs great. It starts first time every time.
Equipment: - Harken roller furler. - Winches have been upgraded to bronze self-tailing Lewmar 30’s. - Headsails: 100% jib, 130% genoa, 155% genoa. Fully-battened main. Spinnaker. Sails are in good condition. - Anchoring: Bow roller with 33 lb Spade anchor. 115 feet of rode. 12lb Danforth high-tensile & 60ft of rode in stern locker. - Simrad TP-10 Tiller pilot - 2 burner Origo 4000 alcohol stove - Porti Potti
Updates: - New group 27 Start battery (1 month ago) - New group 27 House battery (1 month ago) - New fiberglass muffler (1 month ago) - New fuel gauge (1 month ago) - New jib sheets (4 months ago) - Mast rewired, new LED bulbs installed (11 months ago) - New Ritchie compass (12 months ago) - New anchor roller (12 months ago) - New Bimini (12 months ago) - New life lines (18 months ago) - Added second fire extinguisher (20 months ago) - Replaced all hoses attached to thru-hulls (22 months ago) - Replaced exhaust hose (22 months ago) - New exhaust elbow (24 months ago)

Calculations

5.7 kn
Classic: 5.99 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
-
14.8
<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.
- Ballast/Displacement
-
40.0
>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
- Displacement/Length
-
417.7
>400: very 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
-
30.1
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
