Review of Pearson 28 (1975-1980)

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 is equipped with 83.0 liter fresh water capacity.

The Pearson 28 (1975-1980) is equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

The Pearson 28 (1975-1980) has been built with different keel alternatives.

Fin keel

One option is a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.

The boat can enter even shallow marinas as the draft is just about 1.37 - 1.47 meter (4.49 - 4.79 ft) dependent on the load. See immersion rate below.

Fin keel

Another option is 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.

Pearson 28 (1975-1980) can enter most marinas as the draft is just about 1.52 - 1.62 meter (4.99 - 5.29 ft) dependent on the load. See immersion rate below.

The boat may be equipped with an inboard Universal Atomic 4 gasoline engine at 30 hp (22 kW). Calculated max speed is about 7.1 knots

The fuel tank has a capacity of 53.0 liters (14 US gallons, 11 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Pearson 28 (1975-1980) is 1.86, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.6 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Pearson 28 (1975-1980) is about 138 kg/cm, alternatively 774 lbs/inch.
Meaning: if you load 138 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 774 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Pearson 28 (1975-1980) is 24.7.

What is L/B (Length Beam Ratio)?

The l/b ratio for Pearson 28 (1975-1980) is 3.02.

What is a Ballast Ratio?

The ballast ratio for Pearson 28 (1975-1980) is 45%.

What is Displacement Length Ratio?

The DL-ratio for Pearson 28 (1975-1980) is 252 which categorizes this boat among 'light crusers & offshore racers'.

What is SA/D (Sail Area Displacement ratio)?

The SA/D for Pearson 28 (1975-1980) with ISO 8666 reference sail is 15.9, with a 135% genua the SA/D is 18.9.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 23m² (247 ft²).
Based on this, your favourite maritime shop can tell you the quantity you need.

Note: If you use a paint roller you will need more paint than if you use a paintbrush.
