Review of S2 7.3
Basic specs..
The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.
The boat is equipped with 57.0 liter fresh water capacity.
The boat equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.
The S2 7.3 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.
The boat can enter even shallow marinas as the draft is just about 1.22 - 1.32 meter (4.00 - 4.30 ft) dependent on the load. See immersion rate below.
Sailing characteristics
This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.
What is Capsize Screening Formula (CSF)?
The capsize screening value for S2 7.3 is 2.16, indicating that this boat would not be accepted to participate in ocean races.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 5.8 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.
The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for S2 7.3 is about 92 kg/cm, alternatively 516 lbs/inch. Meaning: if you load 92 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 516 lbs cargo on the boat it will sink 1 inch.
Sailing statistics
This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.
What is Motion Comfort Ratio (MCR)?
What is L/B (Length Beam Ratio)?

What is SA/D (Sail Area Displacement ratio)?
Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 15m 2 (161 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

S2 7.3 SD is a 23 ′ 9 ″ / 7.3 m monohull sailboat designed by Graham & Schlageter and built by S2 Yachts starting in 1978.
Rig and Sails
Auxilary power, accomodations, calculations.
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.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
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.
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 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.
Ballast / Displacement * 100
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.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
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.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
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.
CSV = Beam ÷ ³√(D / 64)

Rough day on the water yesterday. I'm a new sailor. It's only my fourth time to have her out. I've been on a bigger boat and this one sails differently. With a small keel it has to sail much flatter. I'll have to adjust and learn. Three of us friends had our boats out. It was cool to be sailing so close to each other. On the way back to my slip I was running the outboard and caught a rope in it. Damn the bad luck. No damage was done.

How is the interior? Hopefully not as bad as Traveller was. Looking back though, and having seen worse, Traveller wasn't horrible but I gutted it anyway.

I finished up connecting my mast electrical as well as all the running lighting. Then I figured that I'd sail. Fawk me. My outboard tore out of its mount and went into Smith Mountain Lake. 🤣 Fortunately I had a line attached to it. It was running when it took the swim. Seems to be fine after I pulled the plugs and exhausted the water.
- Aug 15, 2023
Thought of making the new mount out of 316 stainless. Uh, that's not happening. For what I need it will be around $300 in just material. And, I don't have the equipment to weld it. Looks like it will be fiberglass again. Expect some build content for glassing this thing up.

LENGTH: Traditionally, LOA (length over all) equaled hull length. Today, many builders use LOA to include rail overhangs, bowsprits, etc. and LOD (length on deck) for hull length. That said, LOA may still mean LOD if the builder is being honest and using accepted industry standards developed by groups like the ABYC (American Boat and Yacht Council).
In the late 1970s, S2 did start building powerboats again, and soon established its Tiara line. Slikkers was later able to buy back his old powerboat line, Slickercraft. Production of sailboats ended in 1989. Years in Business: 1974 - 1989. Sailboats Built By S2 Yachts (USA)

The S2 7.3 is a recreational keelboat, built predominantly of fiberglass, with wood trim.It has a masthead sloop rig, a raked stem, a slightly reverse transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel or optional shoal draft keel that was designed by Graham & Schlageter. It displaces 3,250 lb (1,474 kg) and carries 1,300 lb (590 kg) of lead ballast.
The S2 7.3 SD is equipped with a finn keel. The finn keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.
