Basic specs.
The X-372 is a sailboat designed by the maritime architect Niels Jeppesen in the late eighties. A few hundred boats have been produced. The X-372 is built by the Danish yard X-Yachts A/S.
Here we would have liked to show you nice photos of the X-372.

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.
The hull is a double hull which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.
The deck is a double deck which improves the indoor climate.
Interior
The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.
The boat is equipped with 3 cabins, 7 berths, a galley, 110.0liter fresh water capacity and toilet facility.
Rig
The boat has multiple rigs.
One option is a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.
Another option is 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
X-372 can only enter major marinas as the draft is about 2.00 - 2.10 meter (6.56 - 6.86 ft) dependent on the load. See immersion rate below.
Engine
The boat is typically equipped with an inboard Volvo Penta diesel engine at 28hp (20kW). The speed is 8.0 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 70.0liters (18USgallons, 15imperialgallons).
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 X-372 is 2.09, indicating that this boat would not 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 7.3 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-372 is about 215 kg/cm, alternatively 1205 lbs/inch.
Meaning: if you load 215 kg cargo on the boat then it will sink 1 cm.Alternatively, if you load 1205 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 X-372 is 20.6.
Comparing this ratio with similar sailboats show that it is more comfortable than 15% of all similar sailboat designs.This is a comfort value significantly below average.
L/B (Length Beam Ratio)
What is L/B (Length Beam Ratio)?
The l/b ratio for X-372 is 3.10.
Compared with other similar sailboats it is more spacy than 66% of all other designs.It seems that the designer has chosen a slightly more spacy hull design.
Ballast Ratio
What is a Ballast Ratio?
The ballast ratio for X-372 is 43%.
This ballast ratio shows a righting moment that is higher than 69% 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 X-372 is 194 which categorizes this boat among 'light racers'.
76% of all similar sailboat designs are categorized as heavier.A light displacement requires less sailarea and has higher accellerations.
SA/D (Sail Area Displacement ratio)
What is SA/D (Sail Area Displacement ratio)?
The SA/D for X-372 with ISO 8666 reference sail is 21.2, with a 135% genua the SA/D is 24.3.
The SA/D ratio indicates that it is faster than 92% of all similar sailboat designs in light wind.
Over- / underrigged
The X-372 has more rig than 73% of all similar sailboats, which indicates that the boat is slightly overrigged.
RSP (Relative Speed Performance)
What is Relative Speed Performance?
The Relative Speed Performance for X-372 is 93
The relative speed performance is 93 which means that a it is faster than 93% of all similar sailboat designs.
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 38m2 (409 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.
