Review of Sirius 26

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 5 berths.

The boat equipped with 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.

The Sirius 26 is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

The boat can enter even shallow marinas as the draft is just about 1.25 - 1.35 meter (4.10 - 4.40 ft) dependent on the load. See immersion rate below.

Sirius 26 is typically equipped with an inboard engine.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Sirius 26 is 2.17, indicating that this boat would not 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 Sirius 26 is about 136 kg/cm, alternatively 762 lbs/inch.
Meaning: if you load 136 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 762 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Sirius 26 is 2.69.

Compared with other similar sailboats it is more spacy than 82% of all other designs. It seems that the designer has chosen a significantly more spacy hull design.

What is a Ballast Ratio?

The ballast ratio for Sirius 26 is 44%.

This ballast ratio shows a righting moment that is higher than 69% of all similar sailboat designs. A righting moment (ability to resist heeling) just above average.

What is SA/D (Sail Area Displacement ratio)?

The SA/D for Sirius 26 with ISO 8666 reference sail is 16.1, with a 135% genua the SA/D is 19.4.

The SA/D ratio indicates that it is faster than 42% of all similar sailboat designs in light wind.

The Sirius 26 has more rig than 54% of all similar sailboats, which indicates that the boat is slightly overrigged.
