Hull

The hull is made of hand laid fibreglass. Generally, a hull made of hand laid 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.

Interior

The interior is like most other boats made of teak.

The boat is equipped with 4 berths, a galley and toilet facility.

The headroom is above average

Rig

The boat has 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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Arietta is about 121 kg/cm, alternative 678 lbs/inch.

Meaning: if you load 121 kg cargo on the boat then it will sink 1 cm. Alternative, if you load 678 lbs cargo on the boat it will sink 1 inch.

Bottom Paint

When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 14m^{2} (150 ft^{2}).

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.
