Both the hull and the deck is made of fibreglass. A hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The boat is equipped with 6-8 berths and 215 liters (56 US gallons, 47 imperial gallons) fresh water capacity.
Fin keel with bulb
The Delphia 37 is built with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel. The advantage of the bulb is that it lowers the center of gravity which resists heeling and reduces the draft.
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 Delphia 37 is 2.12, indicating that this boat would not be accepted to participate in ocean races.
Delphia 37 holds a CE certification:
The boat is by European Union certified as Class A. OCEAN:What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 7.8 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 Delphia 37 is about 246 kg/cm, alternatively 1381 lbs/inch.
Meaning: if you load 246 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1381 lbs cargo on the boat it will sink 1 inch.
