Seller's Description

Ka Moku Ohana means “The family boat” in polynesian. This 2005 Sundycat is an awesome boat! She is fabulous shape!! The condition of this Sundycat is far better than most similar boats even 1/2 her age! This boat was very well maintained and all of its systems work well. She is ready for use by a beginner or experienced sailor. All of the rigging and hardware is in good working order. The mainsail shows need for minor repairs at the clew and two small holes along the luff, but is fully servicable and has plenty of life. The halyards are in decent shape for a few more seasons, but the down haul line could use to be replaced sooner. All of the standing rigging is solid and well maintained and the running rigging is all safe and operable.

This boat easy to sail, sturdy and safe. Easy to transport, rig and launch from its trailer. A perfect boat for single handed sailing or great for a couple young or old. Great for freshwater or salt, and as capable in open seas as any 21ft boat.

If I made any further changes I would include a small deck winch by the companion way for the halyards, sometimes it would just be nice to have. Additionally Com-Pac can offer a German style sheeting system witch will place the top block near the clew and use two other blocks at each side of the transom. This set up allows for a cleaner cockpit seating area but eliminates the traveler.

Trailer and boat weigh 2500 pounds total.

I’ve sailed this boat 6 different times. Four times in the Chesapeake, twice at the Outer Banks of NC and Wrightsville Beach NC. It is an awesome boat but I have moved on to a full size keel boat and I cant manage two boats.

About photos: Several of the photos were taken last summer at Wrightsville Beach, NC. right after I purchased the boat. The name Sonnenkatz was because the former owner was German. The other photos are from June and August this summer at my home in Charlottesville, VA. , down at Deltaville, VA. on the Chesapeake, or at Ocracoke Island, NC.

Calculations

Hull Speed
6.2 kn
Classic: 5.19 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

6.17 knots
Classic formula: 5.19 knots
Sail Area/Displacement
18.3
16-20: good performance

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.
18.33
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
?

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

?
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
198.6
100-200: light

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
198.56
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
10.5
<20: lightweight racing 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
10.48
<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
2.5
>2.0: better suited for coastal cruising

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
2.53
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

A daysailer model (without the cuddy/cabin) is also available.
