Review of Cal 2-27

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 boat is equipped with 76.0 liter fresh water capacity.

The Cal 2-27 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.

Fin keel

The Cal 2-27 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 full keel.

The boat can enter even shallow marinas as the draft is just about 1.30 - 1.40 meter (4.27 - 4.57 ft) dependent on the load. See immersion rate below.

Cal 2-27 may be equipped with an inboard Universal Atomic 4 gasoline engine at 30 hp (22 kW). Calculated max speed is about 7.4 knots

The fuel tank has a capacity of 95.0 liters (25 US gallons, 20 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Cal 2-27 is 1.96, 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 6.3 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.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Cal 2-27 is about 127 kg/cm, alternatively 712 lbs/inch.
Meaning: if you load 127 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 712 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Cal 2-27 is 22.7.

What is L/B (Length Beam Ratio)?

The l/b ratio for Cal 2-27 is 2.87.

What is a Ballast Ratio?

The ballast ratio for Cal 2-27 is 46%.

What is Displacement Length Ratio?

The DL-ratio for Cal 2-27 is 277 which categorizes this boat among 'medium weight cruisers'.

What is SA/D (Sail Area Displacement ratio)?

The SA/D for Cal 2-27 with ISO 8666 reference sail is 16.9, with a 135% genua the SA/D is 20.3.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 21m² (226 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.
