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. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.
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 core material in the sandwich construction is balsa.
The boat is equipped with a galley, 400.0 liter fresh water capacity, toilet facility and 80.0 liter waste water capacity.
Unknown keel type
The boat can enter most marinas as the draft is just about 1.70 - 1.80 meter (5.58 - 5.88 ft) dependent on the load. See immersion rate below.
Hinrichsen 33 may be equipped with an inboard Vetus Mitsubishi M4.14 engine at 33 hp (24 kW).
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 has a capacity of 180.0 liters (47 US gallons, 39 imperial gallons).
Sailing characteristics
This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Hinrichsen 33 is 1.94, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Hinrichsen 33 is about 232 kg/cm, alternatively 1300 lbs/inch.
Meaning: if you load 232 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1300 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

Maintenance
As balsa wood is used as sandwich core material special care must be taken in relation to work that require penetration of the sandwich construction in order to to prevent water to get in contact with the balsa wood. Otherwise the balsa wood will eventually rotten and be expensive/impossible to repair.
