Review of Norfolk 43

The boat is equipped with 3 cabins, 5 berths, a galley, toilet facility and 50.0 liter waste water capacity.
The headroom is above average

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 Norfolk 43 is equipped with a long keel. A long keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.

The boat can only enter major marinas as the draft is about 1.83 - 1.93 meter (6.00 - 6.30 ft) dependent on the load. See immersion rate below.

Norfolk 43 is typically equipped with an inboard Perkins gasoline engine at 64.0 hp (47 kW), which gives a max speed about 6.5 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 300.0 liters (79 US gallons, 65 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Norfolk 43 is 1.73, 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 7.6 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 Norfolk 43 is about 262 kg/cm, alternatively 1472 lbs/inch.
Meaning: if you load 262 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1472 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Norfolk 43 is 37.9.

Comparing this ratio with similar sailboats show that it is more comfortable than 82% of all similar sailboat designs. This is a comfort value significantly above average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Norfolk 43 is 3.33.

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.

What is a Ballast Ratio?

The ballast ratio for Norfolk 43 is 29%.

This ballast ratio shows a righting moment that is higher than 8% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly below average.

What is Displacement Length Ratio?

The DL-ratio for Norfolk 43 is 349 which categorizes this boat among 'heavy cruisers'.

8% 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 Norfolk 43 with ISO 8666 reference sail is 13.7, with a 135% genua the SA/D is 16.5.

The SA/D ratio indicates that it is faster than 2% of all similar sailboat designs in light wind.

The Norfolk 43 has more rig than 62% of all similar sailboats, which indicates that the boat is slightly overrigged.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 43m² (462 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.
