Hull

The hull is made of hand laid fibreglass while the deck is made of fibreglass. Generally, a hull made of hand laid 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.

Interior

The interior is like many other boats made of mahogany.
The boat is equipped with one cabin, 2 berths and a galley.
Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

Engine

Awi 23 is typically equipped with an inboard Volvo Penta diesel engine at 18.0 hp (13 kW).

The transmission is a shaft drive.

The fuel tank which is made of fibreglass has a capacity of 100 liters (26 US gallons, 21 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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Awi 23 is about 118 kg/cm, alternatively 665 lbs/inch.
Meaning: if you load 118 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 665 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?
