Review of Nauticat 33

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

Both the hull and the deck 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 boat is equipped with 4 cabins, 6-7 berths, a galley, 450.0 liter fresh water capacity and toilet facility.

The Nauticat 33 is equipped with a yawl rig. A yawl rig is generally considered easier to handle, because the sails are smaller, and because it can sail on most points to the wind with one sail completely taken down for repair or while reefing. The sail configuration of a yawl allows for better comfort and stability when sailing downwind or on a broad reach.

Full keel

The Nauticat 33 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.

The boat can enter most marinas as the draft is just about 1.55 - 1.65 meter (5.09 - 5.39 ft) dependent on the load. See immersion rate below.

The Nauticat 33 has been equipped with different engine alternatives.

Alternative 1:

Nauticat 33 may be equipped with an inboard Ford Lehman 2725E diesel engine

Alternative 2:

The boat may be equipped with an inboard Ford diesel engine at 90 hp (67 kW). The speed is 9.0 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenance than other types of drive e.g. a sail drive.

The fuel tank, which is made of stainless steel, has a capacity of 600.0 liters (158 US gallons, 131 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Nauticat 33 is 1.68, 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 7.1 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 Nauticat 33 is about 187 kg/cm, alternatively 1051 lbs/inch.
Meaning: if you load 187 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1051 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Nauticat 33 is 36.4.

What is L/B (Length Beam Ratio)?

The l/b ratio for Nauticat 33 is 3.10.

What is a Ballast Ratio?

The ballast ratio for Nauticat 33 is 33%.

What is Displacement Length Ratio?

The DL-ratio for Nauticat 33 is 328 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 31m² (333 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.
