Hull

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.


Interior

The boat is equipped with 0 cabins, 4-6 berths and 200.0 liter fresh water capacity.

Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

The Y-999 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.


Keel

Unknown keel type

Y-999 can only enter major marinas as the draft is about 1.80 - 1.90 meter (5.91 - 6.21 ft) dependent on the load. See immersion rate below.


Engine

The Y-999 has been equipped with different engine alternatives.

Alternative 1:

The boat may be equipped with an inboard diesel engine at 30 hp (22 kW). Calculated max speed is about 6.3 knots

Alternative 2:

The boat may be equipped with an inboard diesel engine at 20 hp (14 kW). Calculated max speed is about 5.1 knots

The fuel tank has a capacity of 100.0 liters (26 US gallons, 21 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 Y-999 is 1.98, 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 7.2 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 Y-999 is about 202 kg/cm, alternatively 1135 lbs/inch.
Meaning: if you load 202 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1135 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 Y-999 is 24.5.

Low High 50% 0 50 100
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!


L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Y-999 is 2.88.

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


Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Y-999 is 300%.

Low High 100% 0 50 100
This ballast ratio shows a righting moment that is higher than 100% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly above average.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Y-999 is 228 which categorizes this boat among 'light crusers & offshore racers'.

Heavy Light 58% 0 50 100
58% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.


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 35m2 (376 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
