Review of Contest 33

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 6 berths, a galley, 167.0 liter fresh water capacity and toilet facility.

The Contest 33 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.

The Contest 33 has been built with different keel alternatives.

Fin keel

One option is 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 most marinas as the draft is just about 1.67 - 1.77 meter (5.48 - 5.78 ft) dependent on the load. See immersion rate below.

Full keel

Another option is 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.

Contest 33 can enter even shallow marinas as the draft is just about 1.37 - 1.47 meter (4.49 - 4.79 ft) dependent on the load. See immersion rate below.

The boat may be equipped with an inboard Volvo Penta MD2B diesel engine at 25 hp (18 kW). Calculated max speed is about 5.6 knots

The fuel tank has a capacity of 83.0 liters (21 US gallons, 18 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Contest 33 is 1.83, 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 6.8 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 Contest 33 is about 166 kg/cm, alternatively 933 lbs/inch.
Meaning: if you load 166 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 933 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Contest 33 is 28.5.

What is L/B (Length Beam Ratio)?

The l/b ratio for Contest 33 is 3.12.

What is a Ballast Ratio?

The ballast ratio for Contest 33 is 43%.

What is Displacement Length Ratio?

The DL-ratio for Contest 33 is 296 which categorizes this boat among 'medium weight cruisers'.

What is Relative Speed Performance?

The Relative Speed Performance for Contest 33 is 76

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 29m² (312 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.
