Review of Cal 2-46

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

The boat is equipped with a galley, toilet facility and 45.0 liter waste water capacity.
The headroom is above average

The boat equipped with a ketch rig.

The Cal 2-46 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 long keel.

The boat can enter most marinas as the draft is just about 1.52 - 1.62 meter (4.99 - 5.29 ft) dependent on the load. See immersion rate below.

Cal 2-46 is typically equipped with an inboard Perkins 4.236 M diesel engine at 85.0 hp (63 kW), which gives a max speed about 7.7 knots.

The fuel tank which is made of steel has a capacity of 1022.0 liters (269 US gallons, 224 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Cal 2-46 is 1.61, 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 8.2 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 2-46 is about 291 kg/cm, alternatively 1633 lbs/inch.
Meaning: if you load 291 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1633 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Cal 2-46 is 39.9.

Comparing this ratio with similar sailboats show that it is more comfortable than 79% 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 Cal 2-46 is 3.64.

Compared with other similar sailboats it is slimmer than 73% of all other designs. It seems that the designer has chosen a slightly more speedy hull design.

What is a Ballast Ratio?

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

This ballast ratio shows a righting moment that is higher than 12% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly below average.

What is Displacement Length Ratio?

The DL-ratio for Cal 2-46 is 253 which categorizes this boat among 'light crusers & offshore racers'.

42% 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.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 46m² (495 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.
