Hull
The hull is made of wood.
Some boats has a hull made of Fibreglass.

Keel

The boat can enter even shallow marinas as the draft is just about 1.20 - 1.30 meter (3.94 - 4.24 ft) dependent on the load. See immersion rate below.


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 Hallberg-Rassy Misil I is 1.91, 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 6.0 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 Hallberg-Rassy Misil I is about 93 kg/cm, alternatively 522 lbs/inch.
Meaning: if you load 93 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 522 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Hallberg-Rassy Misil I is 19.5.

Low High 69% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 69% of all similar sailboat designs. This comfort value is just above average.


L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Hallberg-Rassy Misil I is 3.20.

Wide Slim 79% 0 50 100
Compared with other similar sailboats it is slimmer than 79% of all other designs. It seems that the designer has chosen a significantly more speedy hull design.


Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Hallberg-Rassy Misil I is 42%.

Low High 62% 0 50 100
This ballast ratio shows a righting moment that is higher than 62% 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 Hallberg-Rassy Misil I is 226 which categorizes this boat among 'light crusers & offshore racers'.

Heavy Light 46% 0 50 100
46% 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)

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

The SA/D for Hallberg-Rassy Misil I with ISO 8666 reference sail is 14.3, with a 135% genua the SA/D is 16.8.

Low High 24% 0 50 100
The SA/D ratio indicates that it is faster than 24% of all similar sailboat designs in light wind.
Don't panic! It is expected that motor sailers has a low SA/D value as this is the natural consequence of the design combining sailing and motor boat characteristics.


Over- / underrigged

Low High 54% 0 50 100
The Hallberg-Rassy Misil I has more rig than 54% of all similar sailboats, which indicates that the boat is slightly overrigged.


RSP (Relative Speed Performance)

What is Relative Speed Performance?

Slow Fast 24% 0 50 100
The relative speed performance is 24 which means that a it is faster than 24% of all similar sailboat designs. As this boat is a motor sailer, it is expected that the performance of a motor sailer for sail alone is lower than a dedicated sailboat.


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 16m2 (172 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.
