Red Witch 19
Red Witch 19 is a 19 ′ 4 ″ / 5.9 m monohull sailboat designed by Per Brohäll and built by Hill & Cameron Yachts starting in 1972.
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)

Review of Red Witch 19
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 equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.
The Red Witch 19 is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.
The boat can enter even shallow marinas as the draft is just about 1.27 - 1.37 meter (4.17 - 4.47 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 Red Witch 19 is 2.62, indicating that this boat would not be accepted to participate in ocean races.
The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Red Witch 19 is about 89 kg/cm, alternatively 498 lbs/inch. Meaning: if you load 89 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 498 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 L/B (Length Beam Ratio)?
What is a Ballast Ratio?
SA/D (Sail Area Displacement ratio) Indicates how fast the boat is in light wind: - Cruising Boats have ratios 10-15 - Cruiser-Racers have ratios 16-20 - Racers have ratios above 20 - High-Performance Racers have ratios above 24 Sail-area/displacement ratio (SA/D ratio): 21.27
Maintenance
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.
| Usage | Length | Diameter | ||
| Jib sheet | 5.9 m | (19.4 feet) | 8 mm | (5/16 inch) |
| Genoa sheet | 5.9 m | (19.4 feet) | 8 mm | (5/16 inch) |

About Red Witch Sailing
Red Witch II is an approximate replica of an early-generation (1914 to 1966) “12-Meter” sailboat – similar to those that raced in the 1920 Olympics and 1958 to 1966 America’s Cup.
SPECIFICATIONS:
Whereas Red Witch II is approved by the U.S. Coast Guard to accommodate 40 passengers, for passenger comfort we prefer to sail with 28 (or fewer) passengers. Red Witch II displaces 19 tons, carries 1,200 square feet of sail, and has an overall length of 55 feet. She has a traditional full keel and cutter sailing rig (with a modern Marconi aka Bermuda-style mainsail). For her era and size she is a fast sailing vessel with a top speed of 12 knots.
“12-METER” AMERICA’S CUP SAILING HISTORY:
Red Witch II is an approximate replica of the early generation of “12-Meter” racing yachts that sailed in the 1920 Olympics and America’s Cup races from 1958 to 1966 – as for the 1967 America’s Cup, “Intrepid ” was the first 12-Meter to shift away from a traditional full keel to a more contemporary “split keel” with fin keel and separate rudder; in the 1983 America’s Cup, “Australia II” was the first 12-Meter to feature a wing keel with spade rudder; and in the 1987 America’s Cup, a 12-Meter introduced a design with two rudders, one aft just of the bow).

SAFETY RECORD
Capt. Andrew R. Sadock (100-Ton Ship’s Master with Sailing and Towing Endorsements) has safely carried 336,000 passengers from Chicago’s Navy Pier, Kenosha Harbor, Los Angeles (Marina Del Rey) and Santa Barbara Harbor (California).
1914-Design America’s Cup Sailing Yacht (replica) Red Witch II (U.S. Coast Guard Official Name “S/V Jakab”) was specifically designed by renowned naval architect Bruce King for ocean racing – fast passage in high waves and wind. Whereas Lake Michigan is renowned for rough sailing conditions on occasion, the prevailing conditions here are well suited for a vessel of Red Witch II’s characteristics and design.
Vintage-design Red Witch III, built in Canada in 1977, was designed by naval architect Alex McGruer specifically to handle the challenging chop (vertical waves) of the Great Lakes. One of Red Witch III’s sisterships crossed the Atlantic Ocean twice. Red Witch III is small yet mighty …
