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 2-4 berths and a galley.
The Stor Triss has been built with different keel alternatives.
Unknown keel type
The boat can enter even shallow marinas as the draft is just about 0.76 - 0.86 meter (2.49 - 2.79 ft) dependent on the load. See immersion rate below.
DaggerBoard aka Sword
The Stor Triss is equipped with a daggerboard keel. A daggerboard is a lifting keel that can be lowered and raised, allowing the boat to enter shallow waters as well.
Stor Triss can enter even shallow marinas as the draft is just about 0.50 - 0.60 meter (1.64 - 1.94 ft) dependent on the load. See immersion rate below.

What is Capsize Screening Formula (CSF)?
The capsize screening value for Stor Triss is 2.68, indicating that this boat would not be accepted to participate in ocean races.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 5.3 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.

Meaning: if you load 62 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 352 lbs cargo on the boat it will sink 1 inch.

Maintenance

The surface of the wet bottom is about 10m2 (107 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.
