Seller's Description
“Christine” is a well maintained center cockpit sailboat, rigged (2 masts), with shoal death keel has navigated the Inner Coastal from Baltimore to the Gulf Coast side of Florida with ease. She has a manual windless (anchor puller upper) with two CQR anchors with chain and rode (rope). The jib is roller furling and the main is boom roller furling fully battened.She has a side entrance cockpit with an aluminum roof which is fully enclosed.Two (240 watts total) solar panels are mounted on the cockpit roof.The forward cabin has its own head with shower. There is a hanging locker across from it with a port and a shelf above. Forward on each side of the V berth are counters with drawers below. The berth is of king sized width at the aft end. The foam cushions are upholstered in pillow ticking. The stern has a huge locker and davits for a dingy. The center cabin has a dinette to starboard and a gallery to port. There is storage under the dinette and at both ends of the seats along the outer side. The galley has an under counter refrigerator which works with either battery or shore power. The alcohol, three burner stove has an oven. The sink has cabinet storage below. Aft of the galley and a step down is double door access to the 55 HP Volvo engine. To port is a slanted, lift top navigation station with sliding door cabinet storage above and two levels of storage below. Next aft is a generous pantry. The AC pump is below. The stern contains a berth on each side with drawers below. The starboard berth presently has a full length shelf used for folding bikes. There is a seat across the stern with wooden book shelves above. The aft head is entered through a door forward and to the left of the starboard berth.The aft head has a sink with counter, a manual toilet and a shower attachment on the sink.
Equipment: Roller furling jib,roller furling maim in boom full battens, engine repowered with volvo 55 hp diesel, chart plotter, dingy davite, 2 120 watt solar panels, led navigation lights and much more. Owner bought bigger boat

Calculations

7.1 kn
Classic: 7.03 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
-
15.8
<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
-
42.2
>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
-
330.8
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
-
33.7
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
