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. 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 2 cabins, 3-5 berths, a galley, 15.0 liter fresh water capacity 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 Scan 22 is 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 gennaker or a spinnaker for optimal speed.

Full keel

The Scan 22 is equipped with a long keel. A full keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated.

Scan 22 can enter even shallow marinas as the draft is just about 1.13 - 1.23 meter (3.71 - 4.01 ft) dependent on the load. See immersion rate below.

An outboard motor is often used on this boat. In that case the boat 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 22.0 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.

What is L/B (Length Beam Ratio)?

The l/b ratio for Scan 22 is 3.32.

What is a Ballast Ratio?

The ballast ratio for Scan 22 is 46%.

What is Displacement Length Ratio?

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

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 12m² (129 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.
