Hull

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

The hull is a double hull which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.

Interior

The interior is like most other boats made of teak.

The boat is equipped with 2 cabins, 5 berths, a galley and toilet facility.

Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

Rig

Keel

The Banner 33 has been built with more than one type of keel.

One option is a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with 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.

Banner 33 can enter most marinas as the draft is just about 1.66 - 1.76 meter (5.45 - 5.75 ft) dependent on the load. See immersion rate below.

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.

Stability and Safety

What is Capsize Screening Formula (CSF)?

The capsize screening value for Banner 33 is 2.08, indicating that this boat would not be accepted to participate in ocean races.

Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.4 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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Banner 33 is about 175 kg/cm, alternatively 981 lbs/inch.

Meaning: if you load 175 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 981 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 31m^{2} (333 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.
