Review of Bianca 36

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

The boat is equipped with 6 berths, a galley and toilet facility.

The Bianca 36 is 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.

Fin keel

The Bianca 36 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 keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.

The boat can only enter major marinas as the draft is about 1.83 - 1.93 meter (6.00 - 6.30 ft) dependent on the load. See immersion rate below.

Bianca 36 may be equipped with an engine at 25 hp (18 kW). Calculated max speed is about 5.1 knots.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Bianca 36 is 1.67, indicating that this boat could - if evaluated by this formula alone - 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 6.8 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. The immersion rate for Bianca 36 is about 158 kg/cm, alternatively 889 lbs/inch.
Meaning: if you load 158 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 889 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Bianca 36 is 3.45.

What is a Ballast Ratio?

The ballast ratio for Bianca 36 is 43%.

What is Displacement Length Ratio?

The DL-ratio for Bianca 36 is 368 which categorizes this boat among 'heavy cruisers'.

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

The SA/D for Bianca 36 with ISO 8666 reference sail is 14.1, with a 135% genua the SA/D is 17.0.

What is Relative Speed Performance?

The Relative Speed Performance for Bianca 36 is 50

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 28m² (301 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.
