Review of Pearson 33 Mk II

Both the hull and the deck 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 3 cabins, 6 berths, toilet facility and 37.0 liter waste water capacity.

The boat 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 33 Mk II has been built with more than one type of keel.

One 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.But be aware that even though a Keel/Cbrd. keel is very good for speed racing, a fishing nets and the like in the water can easily make you into a troublesome situation.

Another option is a centerboard keel. A centerboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The boat can enter even shallow marinas as the draft is just about 1.10 - 1.20 meter (3.61 - 3.91 ft) dependent on the load. See immersion rate below.

Pearson 33 Mk II is typically equipped with an inboard Yanmar 2GM20F diesel engine at 18.0 hp (13 kW), which gives a max speed about 4.9 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.

The fuel tank has a capacity of 68.0 liters (17 US gallons, 14 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Pearson 33 Mk II is 1.98, 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 6.9 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 33 Mk II is about 179 kg/cm, alternatively 1005 lbs/inch.
Meaning: if you load 179 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1005 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Pearson 33 Mk II is 24.7.

Comparing this ratio with similar sailboats show that it is more comfortable than 50% of all similar sailboat designs. This is an average comfort value!

What is L/B (Length Beam Ratio)?

The l/b ratio for Pearson 33 Mk II is 2.96.

Compared with other similar sailboats it is more spacy than 73% of all other designs. It seems that the designer has chosen a slightly more spacy hull design.

What is a Ballast Ratio?

The ballast ratio for Pearson 33 Mk II is 40%.

This ballast ratio shows a righting moment that is higher than 46% of all similar sailboat designs. A righting moment (ability to resist heeling) just below average.

What is Displacement Length Ratio?

The DL-ratio for Pearson 33 Mk II is 272 which categorizes this boat among 'light crusers & offshore racers'.

38% 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.

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

The SA/D for Pearson 33 Mk II with ISO 8666 reference sail is 16.5, with a 135% genua the SA/D is 19.6.

The SA/D ratio indicates that it is faster than 46% of all similar sailboat designs in light wind.

The Pearson 33 Mk II has more rig than 21% of all similar sailboats, which indicates that the boat is significantly underrigged.

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.
