Review of Scan 22

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.

The interior is like many other boats made of mahogany.
The boat is equipped with 2 cabins, 3-5 berths, a galley and toilet facility.
Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

The boat equipped with 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.

An outboard motor is often used on this boat. In that case Scan 22 will typically require a power of 4 - 5 hp, alternatively 92 - 111 lbs thrust if you prefer an electrical motor. Electric outboards are becoming popular for sailboat owners who want clean instant power with less noise and no exhaust fumes.

The fuel tank has a capacity of 22 liters (5 US gallons, 4 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Scan 22 is 1.57, indicating that this boat could - if evaluated by this formula alone - 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 5.5 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 Scan 22 is about 68 kg/cm, alternatively 383 lbs/inch.
Meaning: if you load 68 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 383 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Scan 22 is 31.8.

Comparing this ratio with similar sailboats show that it is more comfortable than 100% of all similar sailboat designs. This is a comfort value significantly above average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Scan 22 is 3.32.

Compared with other similar sailboats it is slimmer than 93% of all other designs. It seems that the designer has chosen a significantly more speedy hull design. This type of design is also referred to as 'needle'.

What is Displacement Length Ratio?

The DL-ratio for Scan 22 is 428 which categorizes this boat among 'heavy cruisers'.

0% 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.
