Calculations

Hull Speed
8.4 kn
Classic: 8.13 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

8.36 knots
Classic formula: 8.13 knots
Sail Area/Displacement
17.0
16-20: good performance

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.
17.04
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
34.7
<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

34.65
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
316.9
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
316.88
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
42.4
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
42.42
<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
1.6
<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
1.61
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

From BlueWaterBoats.org:

Still available today under special order, the Hans Christian 41 Traditional was first introduced in 1985. The name Hans Christian conjures up associations with boats that are heavy, sometimes slow, but always seakindly; boats that are laden with teak and luxury interiors wrapped into the form of a traditionally styled of a canoe-stern double ender. We’re talking big bowsprits, high bulwarks, butterfly hatches, husky bronze fittings and a kind of character that speaks of seaworthiness that has its roots in American popularity with the introduction of the Crealock’s Westsail 32 in 1973.

As a 41 footer weighing in at over 40,000 pounds in typical cruising trim, she’s in a class of its own as a heavy displacement cruiser. Influenced by the latest design thinking of the time, the underwater form has a split keel arrangement somewhat similar to company’s Telstar Keel first appearing on the Hans Christian 38 Traditional in 1984 where it helped with close windedness and light air performance.

Aided by her split keel, the 41 Traditional has been described as an easy boat to sail. When comparing speed to others in the range, the 41T is slower than the Telstar 43T and it’s said the smaller 38T with Telstar Keel can just pip the 41T in ideal conditions. Also don’t expect a lot of light air performance given her displacement, then again owners of Hans Christian boats are not looking for speed but rather comfort. In this department, the boat excels with a gentle seakindly motion in a manner only heavy boats can deliver.

History

Hans Christian Yachts has forged a name for itself starting in the early 1970s using quality Taiwanese boatyards; its founder, John Edwards has always had an eye for spying talent. Notable boats include the Bob Perry designed and much copied 34T, Harwood Ives’ space efficient 33T, and of course the classic 38T and its MkII sequel.

By late 1984, the company played with the idea of a new boat with focus on interior and a hull form that would bring it up to date with the latest design thinking. The result was the Hans Christian 41 Traditional, which at its introduction in 1985 gave the company an offering that slotted between their two 38 models and the 43. As Craig Beckwith, VP of Sales during that period puts it:

“The decision to build the 41, as always, began over a bottle or two of beer after the days end, and progressed to fruition. The thought was that we needed a bigger version of the 38 MkII, that had the galley of the 38 Traditional, the forward head arrangement from the 33 Traditional (which had proved popular), and a split keel to move into the more modern designs of Perry, Frers, and other designers that touted the long-cord fin with skeg-mounted rudder. The 41 Traditional was a collection of all the things we had learned throughout the process of building the older models, and listening carefully to the clients and watching the market develop.”

The design came from Scott Sprague with a lot of input from Edwards. Sprague at the time had become Hans Christian’s chief designer after the departure of Harwood Ives who had penned many of the prior boats.

“Scott designed the 48 Traditional first, and then with John Edwards, pulled together the general design of the 41 Traditional. Here again, John’s ability to pick out young designers with really high degree of talent came into play. Scott’s father did all the technical work for Bill Garden, and Scott grew up in a design oriented family. He had a natural talent for design and technical ability.” – Craig Beckwith

The first boats were built in Taiwan by South Coast Ship Building Yard until Hans Christian Yachts relocated to Thailand in 1990 to stay competitive. In Thailand the progression of builders went from Dutch East Indies Trading Co (founded by Edwards), Andersen Yachts, and eventually Pantawee Marine who currently builds all of the boats from the Hans Christian line. In total 55 boats have been built.

Interior Layout

It’s probably best to describe the boats as being semi-custom in nature. There were at least five variations of layouts; four were described in the original brochure and named the Molokai, Harmony, Atlantic and Pacific. The most popular was the Molokai layout with its twin head arrangement and double berths both forward and aft; this has been the standard and only layout that has been built since 1994. We also know of a fifth layout similar layout to the Molokai but with workshops replacing the area where the after quarter-berth normally resides, only two of these were built.

Interiors are of a very high workmanship and incorporate many ideas that proved popular for Hans Christian in prior models.
