Farr 727 is a 23 ′ 9 ″ / 7.3 m monohull sailboat designed by Bruce Farr and built by Chantier Mallard and Hughes Boat Works starting in 1976.
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)
Prototype was winner of the Int. 1/4 ton cup(1975). Boats built by Northstar Yachts of Canada, were called the NORTHSTAR 727.

Review of Farr 727
Basic specs..
The Farr 727 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.
The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated. As the surface of a finn type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.
The boat can enter most marinas as the draft is just about 1.50 - 1.60 meter (4.92 - 5.22 ft) dependent on the load. See immersion rate below.
Farr 727 is typically equipped with an inboard engine.
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 Farr 727 is 2.39, 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 5.9 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 Farr 727 is about 101 kg/cm, alternatively 566 lbs/inch. Meaning: if you load 101 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 566 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 a Ballast Ratio?
What is Displacement Length Ratio?
What is Relative Speed Performance?
Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 18m 2 (193 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.
If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.

Design No. 37 represents a more serious approach to the IOR Rule than was taken with Design No. 27, although cruising considerations are still evident in the form of built-in berths and more than Rule requirement headroom. The design has more beam and more sail relative to length, and the rig is nearer to 3/4 proportions with larger mainsail compared to headsail than was the case with Design No. 27. The keel is deeper and narrower, with center of gravity located high up to produce a minimum C.G.F. factor under the Rule, and is not designed with any consideration of drying the boat out alongside piles, as was the case with earlier designs. The cockpit is clearly designed around cruising requirements with seats and protective coamings, but the deck layout is organized as efficiently as could be achieved within those limitations.
FANTZIPANTZ, the prototype of Design No. 37, displayed such superiority in boat speed and comfort that Farr was immediately approached to produce the boat in fiberglass. Farr developed the FANTZIPANTZ design to take full advantage of new construction materials and at the same time took into account lessons learned during racing and cruising FANTZIPANTZ. The FARR 727, (as the production model is named) is slightly longer with broader sections aft, less rated sail area and again rated 1/4 Ton. The FARR 727 still contains cruising compromises which resulted in a useful small cruising yacht as well as a World Championship winning race boat.
