Review of Contrast 345

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

The hull is a sandwich construction 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 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 8 berths, a galley, 125.0 liter fresh water capacity, toilet facility and 55.0 liter waste water capacity.

The Contrast 345 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.

Unknown keel type

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can enter most marinas as the draft is just about 1.75 - 1.85 meter (5.74 - 6.04 ft) dependent on the load. See immersion rate below.

The Contrast 345 has been equipped with different engine alternatives.

Alternative 1:

Contrast 345 may be equipped with an inboard Yanmar 3GM20SD diesel engine

The transmission is a saildrive.

Alternative 2:

The boat may be equipped with an inboard Volvo Penta engine

The transmission is a saildrive.

The fuel tank has a capacity of 70.0 liters (18 US gallons, 15 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Contrast 345 is 2.06, indicating that this boat would not 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 7.2 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 Contrast 345 is about 198 kg/cm, alternatively 1109 lbs/inch.
Meaning: if you load 198 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1109 lbs cargo on the boat it will sink 1 inch.

The Motion Comfort Ratio for Contrast 345 is 20.3.

What is L/B (Length Beam Ratio)?

The l/b ratio for Contrast 345 is 3.11.

What is a Ballast Ratio?

The ballast ratio for Contrast 345 is 43%.

What is Displacement Length Ratio?

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 34m² (365 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.
