Calculations

Hull Speed
7.9 kn
Classic: 7.87 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

7.87 knots
Classic formula: 7.87 knots
Sail Area/Displacement
12.8
<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.
12.84
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
26.6
<40: less stiff, less 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

26.57
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
347.5
275-350: 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
347.46
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
41.4
40-50: heavy bluewater 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
41.38
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
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
1.68
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

From BlueWaterBoats.org:

Bill Hardin, probably best known for being a pioneer of the Taiwanese boat building industry for the American market, penned the Hardin 45 “Voyager” in the late 1970s. It’s a heavy displacement bluewater boat particularly well set up for cruising in comfort and style. The boats were built between 1977 and 1982 in Kaohsiung Taiwan by Hardin International and sold through their U.S. distributor, East-West Yachts in Marina Del Rey, California. Originally built and sold as the Bounty 44, the boat got an update in 1980 when Hardin made some significant changes. These included extending the boat length to 45′ 2″ and a six inch reduction in draft from to five and a half. Along the way the transom was trimmed down and a couple of portlights in the hull were relocated to the aft cabin top. To reduce confusion to customers who often wouldn’t notice the difference, dealers would refer to both boats as the Hardin 45.

The boats were generally of quality construction with excellent structural integrity and good joiner work. A total of around 130 Hardin 45s were built by the time the factory closed in the mid 1980s.

These center-cockpit designs had most of their attention in their beautiful and spacious interiors finished in hand crafted teak. The centrepiece of the accommodations is a split level salon giving an open and airy feel due to the copious amounts of light coming in from the raised salon glass, portlights and butterfly hatch. On the lower of the split levels were two seagoing berths. In the mid-cabin forward of this area are two pilot berths, many use this area as a “storage garage” while on some boats of this area was modified to make room for a larger master head with tub/shower combination. There’s also large aft stateroom with an additional head. A few boats were built for chartering which crammed more berths into the layout. They had a v-berth as well as a double cabin stateroom forward of the salon.

It seems most of the thought behind the design of Hardin 45 was to optimize the experience under anchor. With so much glass above deck (bringing in that all important “light and airy” feel), it’s nearly essential for those planning bluewater passages to have a set of storm shutters for all of that glass. Fiberglass storm shutters were offered by the factory back in the day, but not many took the offer.

At 32,000 pounds The Hardin 45 is well and truly in the heavy boat category with weak light air performance. Yet on the other end of the spectrum, with only 25% of their weight in the ballast with shoal draft keel, they don’t go very far in blow. They are however very comfortable.

At least one Hardin owned by Gordon and Joan Mery has been credited with a nine year circumnavigation, they commented after 38,000 miles under their keel, “it isn’t that fast for a boat, but she’s pretty quick for a house”. Another owner having singlehanded 10,000 miles in his Hardin confirms she is “solid slow and comfortable” and tells of an episode where he was caught in a 75 mph blow with twenty foot breaking seas saying, “I didn’t go anywhere, but it was comfy”.
