Seller's Description

MUST SEE TO APPRECIATE!

KARMA was designed by Sparkman & Stephens for safe and comfortable bluewater cruising. Her hand laid solid fiberglass hull is over 1 thick below the waterline. Karma also has integrated and baffled fiberglass tanks which eliminates the problems associated with older metal tanks. With 400 gallons of water and 400 gallons of fuel, Karma is well suited for off shore passages. The skeg supported rudder and cut away front full keel make her very safe, stable and comfortable at sea. The center cockpit design allows for generous headroom below. The cockpit itself is very large and comfortable with deep seating and high back rests. Add to that the water tight bimini and full enclosure, you are not only comfortable at sea you are protected from the elements.

The cutter ketch combination allows easy set up for all weather conditions for a crew of two. There is plenty of room on deck to store cruising gear and the tender.

Her accommodations include a large salon with 7’ headroom, L-shaped galley with abundant storage and three refrigerator/freezer units, three staterooms and two heads. Her solid teak, mahogany and ash joinery is stunning and has been well cared for.

This particular boat is sistership to Walter Cronkite’s beloved Sunward 48, WYNTJE and was featured in the TV series Dawson’s Creek. This hull was built and completed at the Sunward Yacht facility in Wilmington, NC.

KARMA has been cruising for the past 9.5 years and her seller’s are ready for their next adventure. She set sail from Florida in 2011, and cruised approximately 20,000 miles before her arrival in San Diego, CA.

Many spare parts for all systems are included. Maintenance records are available.

Calculations

Hull Speed
8.0 kn
Classic: 8.31 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

8.0 knots
Classic formula: 8.31 knots
Sail Area/Displacement
12.9
<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.
12.86
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
33.0
<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

33.0
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
391.6
>350: ultraheavy

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
391.63
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
54.0
>50: extremely heavy bluewater 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
53.97
<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
1.6
<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
1.55
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

S&S design #1674.2.
Based on an earlier production model called the MARLOW 48.
