Seller's Description
This 2006 Precision 21’ fractional sloop sailboat is ready for her next owner. The owner has moved some distance away and is not able to use her often enough.
The owner says she is extremely sturdy and handles very well!
The great care that both designer and builder have put into the development of the Precision 21 is perhaps most clearly reflected in her interior. Her main cabin berths are laid out properly fore and aft and there is a porta-potty just aft of the forward berth.
The galley is not an awkward slide-away module, but a solidly built-in unit with a stainless sink, garbage bin, and alcohol stove. A 48-quart cooler conveniently serves as the step between the cabin and cockpit, and the battery box is located just aft of the starboard quarter berth and is accessible from inside the cabin or via the large starboard lazarette.
The centerboard pendant tube is protected by being fully enclosed and molded into the cockpit sole. The cockpit is over 7 feet long, and features seats and coamings precisely angled for comfort both when upright and when heeled.
The inboard chain plates not only allow exceptionally close-winded performance to weather but also leave ample side decks clear, providing unobstructed passage past the sleekly styled cabin house to the anchor locker forward.
The sail inventory includes the mainsail, a jib, and a genoa, all according to the seller, very serviceable.
The ground tackle includes a Fortress FX-7 anchor, chain, and a significant length of rode (exact length unknown).
When not under sail the boat is powered by a Honda 4-stroke 2 HP engine.
The boat rides on a 2005 Performance galvanized single-axle trailer. The trailer has bow access steps and a forward pulley for making the stepping and un-stepping of the mast easier.
There are canvas covers for the mainsail and the entire deck. Although the covers do not appear to have any significant holes or tears, they are due for a good “scrubbing”.

Calculations
- Hull Speed
-
7.2 kn
Classic: 5.6 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
-
21.4
>20: high 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.
- Ballast/Displacement
-
32.0
<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
-
156.5
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
- Comfort Ratio
-
9.4
<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
- Capsize Screening
-
2.7
>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
