Looking for a new boat? Find a Delphia 47 or similar boat for sale
The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The boat is equipped with 10+2 berths and 460.0 liter fresh water capacity.
The Delphia 47 is equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.
Full keel
The Delphia 47 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 boat can only enter major marinas as the draft is about 2.30 - 2.40 meter (7.55 - 7.85 ft) dependent on the load. See immersion rate below.
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 47 is 1.92, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
Delphia 47 holds a CE certification:
The boat is by European Union certified as Class A. OCEAN:The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Delphia 47 is about 422 kg/cm, alternatively 2363 lbs/inch.
Meaning: if you load 422 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2363 lbs cargo on the boat it will sink 1 inch.
