The hull is made of fibreglass. Generally, a hull made of 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.
The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.
The boat is equipped with 7 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.
Unknown keel type
Jupiter 25 can enter even shallow marinas as the draft is just about 0.96 - 1.06 meter (3.15 - 3.45 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.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Jupiter 25 is about 142 kg/cm, alternatively 799 lbs/inch.
Meaning: if you load 142 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 799 lbs cargo on the boat it will sink 1 inch.
