The Petit Prince 115 is built with a cutter rig. A cutter rig breaks the yacht’s sail area down into smaller, easier to manage sails. Cutter rigs are often used for offshore sailing.
Unknown keel type
The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.
The boat can only enter major marinas as the draft is about 1.80 - 1.90 meter (5.91 - 6.21 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 Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 7.4 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 Petit Prince 115 is about 248 kg/cm, alternatively 1393 lbs/inch.
Meaning: if you load 248 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1393 lbs cargo on the boat it will sink 1 inch.
