Calculations
- Hull Speed

6.6 kn
Classic: 6.63 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
-
14.4
<16: under powered
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
- ?
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
-
348.7
300-400: heavy
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
-
32.8
30-40: moderate bluewater cruising 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
-
1.7
<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
DOUGLAS 32 is like 31 with extended reverse transom.
Similar to HULLMASTER 31, ALCONA 31.
HISTORY:
DOUGLAS MARINE CRAFT - Douglas Badgley commissioned Ted Brewer to design the original Douglas 31s. His company, Douglas Marine Craft, built them in Port Stanley, Ontario, starting in 1967. Around 1970-1971 Douglas Yachts went out of business, and the molds were reportedly seized by creditors.
NORTH AMERICAN FIBREGLAS MOULDINGS - Jeffrey White of North American Fiberglas Moldings Ltd. in London, Ontario acquired at least one set of DOUGLAS 31 hull and deck molds, and modified them with a reverse transom designed by Ted Brewer to create the DOUGLAS 32.(shown here)
COMMAND YACHTS - In 1974, North American Fiberglas went into receivership and emerged as Command Yachts with the same crew and president, and a new model - The D-32 MKII. Command Yachts was purchased by De Leuw Cather Canada who dissolved the boat building division around 1976.
THE FIRST “KIT” BOATS- BRUCE PENINSULA YACHTS - Apparently, the D-32 molds were then acquired by Bruce Peninsula Yachts, who produced the first kit boats with all the original molds including those for the interior layout. While the location of the molds is currently unknown, production rights are still owned by Mary Ellen Duncan, former wife of Bruce Lapier, who together formed Bruce Peninsula Yachts.
HULLMASTER BOATS, LTD. - Hullmaster Boats, LTD acquired one or more of the original Douglas 31 molds about the same time as North American Fibreglas Mouldings, and concurrently built HULLMASTER 31s in Picton, Ontario. The last HULLMASTER 31 was built in 1979.
When Hullmaster went out of business, Doug Smith acquired the DOUGLAS 31 molds.
J&C FIBERCRAFT - It has been said that Doug Smith later sold his business to Jed & Carol Benoit of J&C Fibercraft. It appears that J&C D-31s are direct descendants of Hullmaster. Either way, custom yachts of a high quality as well as kit boats from the D-31 molds were built by this company in Barrie, Ontario.
HINTERHOELLER - It is believed that the last six D-31 hulls were built and delivered as kit boats by Hinterhoeller Yachts out of Ontario around 1982.
