Seller's Description

The following is an extract from a Bill Shaw write-up (he designed the 28-2).

The new Pearson 28 is our third generation of boats this size, and represents the very latest thinking in design, engineering, and owner preferences. A quick glance at her 24’4 1/2” waterline length and 9’10” beam dimensions indicate just how spacious she is. Truly, an extremely accommodating 28 footer. The challenge was to use this space to maximum advantage and this is where our design group has carved out new territory. For example, there are two real double berths - one forward and another enclosed stateroom aft to port - they provide desirable privacy while the enclosed head is located further aft than we have seen recently using a wider part of the boat to its best advantage. The galley is located amidships with stove, sink, and stowage to port, and with a large ice box covered by an equally large chart table/counter to starboard. For a smaller boat, this is a superior arrangement as it maximizes galley work space and ice box volume. The 28’s sailing qualities are superb. Of particular note is her ability to stand up to a breeze due mainly to the form stability produced by her wide beam at the waterline. We set out to design a performance cruiser/racer and from all appearances, we succeeded. And one more thing. To summarize, the 28 is what you’ve come to expect from Pearson. She is uniquely different and, in our opinion, just right for the requirements of today’s sailors. Namely, quality, excellent sailing characteristics, sea-kindly motion, spaciousness, and privacy.

Calculations

Hull Speed
7.7 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

7.71 knots
Classic formula: 6.63 knots
Sail Area/Displacement
16.8
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.
16.75
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
36.4
<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

36.44
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
213.1
200-300: moderate

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
213.14
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
19.9
<20: lightweight racing 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
19.91
<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
2.1
>2.0: better suited for coastal cruising

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
2.06
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Shoal draft: 3.50’ / 1.07m
Disp.: 7350 lbs./3334 kgs
Not to be confused with an earlier PEARSON 28, also by Shaw, and discontinued in 1982.
