Seller's Description
Sparkman & Stevens designed a fast, fun cruiser that were often raced locally. She has pleasant lines and this one has had the mast, deck and cockpit recently painted with DuPont Imron. The owner has been steadily upgrading the boat. The standing rigging was replaced 5 yrs ago and the sails are reasonably good. The engine was replaced with a new Yanmar diesel w/80amp alternator in 2005. The electronics are recent and very good. The interior needs some work but the basic systems are all there and working well. The fuel and water tanks have been addressed. She should be fun to sail.
Equipment: 60 lb Spade primary anchor with 300ft of 5/16”and deck wash. Four other anchors on board. 12V Windlass needs motor replaced. New 440AH house batteries w/ separate new start battery. 400 watts of solar panels w/Solar Boost 2000E regulator. 30amp ProNautic battery charger. Recent Raymarine ST-60 wind/water instruments. Icom 802 SSB w/Pactor modem. Icom 424 VHF. Garmin 943 Chartplotter-no radar dome. Raymarine EV-400 autopilot. Monitor wind vane. Frigoboat refrigeration. Force Ten 3 burner stove/oven. Manual LaVac toilet and pump. There sails are 8oz mainsail2009, 135% mylar genoa 2009, staysail, storm jib, 1/2oz spinnaker, and 2oz assymetrical geniker. Winches are plentiful with some newer Lewmar 46STs. 6man Switlik life raft. Walker Bay 270 dinghy 2018 w/ 6HP Tohatsu outboard 2006.

Calculations
- Hull Speed

8.7 kn
Classic: 7.66 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
-
17.0
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
-
51.5
>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
-
228.4
200-300: moderate
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
-
27.8
20-30: coastal cruiser
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
-
1.9
<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
Notes
S&S design #2095.
The rudder and keel on some of the early boats proved to be undersized, which caused steering problems in stronger winds. (The boat in the photo above may have been one of these!)
Several were re-equipped by S&S with a lead shoe at the bottom of the keel, increasing the draft slightly but improving stability. In 1974 S&S designed a new keel which fitted onto the old bolt pattern, increasing the draft by 7” and displacement by 700 lbs. Though this was offered as an option, most of the last 20 boats were delivered with this new keel and many earlier boats had them retro-fitted.
(Deeper draft: )
The molds were actually first created to build the TARTAN 43 and later adapted for the 41, which proved to be a far more popular model.
