Review of Pearson 365

Basic specs.

The Pearson 365 is a sailboat designed by the American maritime architect William H. Shaw in the mid seventies. The Pearson 365 is built by the American yard Pearson Yachts.

Here we would have liked to show you nice photos of the Pearson 365.

Hull

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

Interior

The boat is equipped with 2 cabins, 4 berths, a galley, 568.0 liter fresh water capacity and toilet facility.

Rig

The Pearson 365 is equipped with a ketch rig. A ketch rig is generally considered easier to handle, because the sails are smaller, and because it can sail on most points to the wind with one sail completely taken down for repair or while reefing. The sail configuration of a ketch allows for better comfort and stability when sailing downwind or on a broad reach.

Keel

Unknown keel type

The boat can enter even shallow marinas as the draft is just about 1.35 - 1.45 meter (4.43 - 4.73 ft) dependent on the load. See immersion rate below.

Engine

The Pearson 365 has been equipped with different engine alternatives.

Alternative 1:

Pearson 365 may be equipped with an inboard Perkins 4.108 diesel engine at 41 hp (30 kW). Calculated max speed is about 6.2 knots

Alternative 2:

The boat may be equipped with a diesel engine.

The fuel tank has a capacity of 189.0 liters (49 US gallons, 41 imperial gallons).

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

Stability and Safety

What is Capsize Screening Formula (CSF)?

The capsize screening value for Pearson 365 is 1.75, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.3 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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Pearson 365 is about 213 kg/cm, alternatively 1193 lbs/inch.
Meaning: if you load 213 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1193 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

Motion Comfort Ratio

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Pearson 365 is 33.1.

Comparing this ratio with similar sailboats show that it is more comfortable than 79% of all similar sailboat designs. This is a comfort value significantly above average.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Pearson 365 is 3.19.

Compared with other similar sailboats it is more spacy than 54% of all other designs. It seems that the designer has chosen a slightly more spacy hull design.

Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Pearson 365 is 41%.

This ballast ratio shows a righting moment that is higher than 58% of all similar sailboat designs. A righting moment (ability to resist heeling) just above average.

D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Pearson 365 is 291 which categorizes this boat among 'medium weight cruisers'.

34% of all similar sailboat designs are categorized as heavier. A heavy displacement combined with smaller water plane area has lower acceleration and is more comfortable.

SA/D (Sail Area Displacement ratio)

SA/D (Sail Area Displacement ratio)
Indicates how fast the boat is in light wind:
- Cruising Boats have ratios 10-15
- Cruiser-Racers have ratios 16-20
- Racers have ratios above 20
- High-Performance Racers have ratios above 24
Sail-area/displacement ratio (SA/D ratio): 14.49

Maintenance

Bottom Paint

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 33m² (355 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.

Rig

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.

**Guiding dimensions of running rig**
Usage	Length		Diameter
Jib sheet	11.1 m	(36.4 feet)	14 mm	(0.55 inch)
Genoa sheet	11.1 m	(36.4 feet)	14 mm	(0.55 inch)
Mainsheet	27.8 m	(91.0 feet)	14 mm	(0.55 inch)
Spinnaker sheet	24.4 m	(80.1 feet)	14 mm	(0.55 inch)
