Hull

The hull 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 interior is like many other boats made of mahogany.

The boat is equipped with 3 cabins, 4 berths, a galley and toilet facility.

Rig

Rig of X-302 anno 1999.

Keel

The X-302 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long keel.

The boat can enter most marinas as the draft is just about 1.75 - 1.85 meter (5.74 - 6.04 ft) dependent on the load. See immersion rate below.

Engine

X-302 is typically equipped with an inboard diesel engine at 9.0 hp (6 kW), which gives a max speed about 4.1 knots.

The fuel tank has a capacity of 50.0 liters (13 US gallons, 10 imperial gallons).

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 X-302 is 1.97, 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 6.9 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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for X-302 is about 161 kg/cm, alternatively 906 lbs/inch.

Meaning: if you load 161 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 906 lbs cargo on the boat it will sink 1 inch.

Ballast Ratio

The ballast ratio for X-302 is 42%.

D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for X-302 is 192 which categorizes this boat among 'light racers'.

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): 20.99

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 29m^{2} (312 ft^{2}).

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.
