Review of X-452

The hull is made of hand laid fibreglass while the deck is made of fibreglass. Generally, a hull made of hand laid fibreglass requires only a minimum of maintenance during the sailing season.

The interior is like most other boats made of teak. Teak has the advantage of being naturally very oily and therefore water-repellent, which is suitable on boats.
The boat is equipped with 0 cabins, 10 berths, a galley, 280.0 liter fresh water capacity and toilet facility.

The X-452 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.

The X-452 has been built with different keel alternatives.

Unknown keel type

The boat can only enter major marinas as the draft is about 2.50 - 2.60 meter (8.20 - 8.50 ft) dependent on the load. See immersion rate below.

Fin keel

The X-452 is equipped with 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.

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

X-452 can only enter major marinas as the draft is about 2.50 - 2.60 meter (8.20 - 8.50 ft) dependent on the load. See immersion rate below.

The boat may be equipped with an inboard Yanmar diesel engine at 55 hp (40 kW). The speed is 9.0 knots.

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

The fuel tank, which is made of stainless steel, has a capacity of 200.0 liters (52 US gallons, 43 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for X-452 is 2.07, indicating that this boat would not 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 8.0 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.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for X-452 is about 306 kg/cm, alternatively 1718 lbs/inch.
Meaning: if you load 306 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1718 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for X-452 is 23.8.

What is L/B (Length Beam Ratio)?

The l/b ratio for X-452 is 3.16.

What is a Ballast Ratio?

The ballast ratio for X-452 is 44%.

What is Displacement Length Ratio?

The DL-ratio for X-452 is 200 which categorizes this boat among 'light racers'.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 55m² (592 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.

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
