The hull is made of fibreglass. A hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The hull shape is deep V. Generally, a deep V hull gives a more comfortable cruise because it helps the boat cut through waves while minimizing impacts, help the boat bank into turns, and throw less spray. However, a deep V hull reduces stability and requires more power.
The boat is equipped with 3 cabins, 6 berths, a galley, 757 liters (199 US gallons, 166 imperial gallons) fresh water capacity and 150 liters (39 US gallons, 32 imperial gallons) waste water capacity.
The fuel tank has a capacity of 3028 liters (799 US gallons, 666 imperial gallons).
The boat may be equipped with an inboard Cummins QSB 6.7 diesel engine at 550 hp (409 kW). Cruise speed is 19.0 knots. Max speed is 24.0 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.

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 Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 8.8 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 Alden 50 (Hunt) is about 423 kg/cm, alternatively 2372 lbs/inch.
Meaning: if you load 423 kg cargo on the boat then it will sink 1 cm.

When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 66m2 (710 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.
