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 boat is equipped with 6 berths, a galley and toilet facility.
Unknown keel type
The boat can enter most marinas as the draft is just about 1.70 - 1.80 meter (5.58 - 5.88 ft) dependent on the load. See immersion rate below.
Optima HT may be equipped with an inboard Farymann engine at 10 hp (7 kW).
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 Optima HT is 1.92, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Optima HT is about 180 kg/cm, alternatively 1011 lbs/inch.
Meaning: if you load 180 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1011 lbs cargo on the boat it will sink 1 inch.
