Review of Drabant 21

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

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 Drabant 21 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.

Drabant 21 can enter even shallow marinas as the draft is just about 1.15 - 1.25 meter (3.77 - 4.07 ft) dependent on the load. See immersion rate below.

An outboard motor is often used on this boat. In that case the boat will typically require a power of 2 - 3 hp, alternatively 48 - 57 lbs thrust if you prefer an electrical motor. Electric outboards are becoming popular for sailboat owners who want clean instant power with less noise and no exhaust fumes.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Drabant 21 is 2.11, 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 Drabant 21 is about 96 kg/cm, alternatively 540 lbs/inch.
Meaning: if you load 96 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 540 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Drabant 21 is 3.12.

Compared with other similar sailboats it is slimmer than 79% of all other designs. It seems that the designer has chosen a significantly more speedy hull design.

What is a Ballast Ratio?

The ballast ratio for Drabant 21 is 50%.

This ballast ratio shows a righting moment that is higher than 88% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly above average.

What is Relative Speed Performance?

The Relative Speed Performance for Drabant 21 is 66

The relative speed performance is 66 which means that a it is faster than 66% of all similar sailboat designs.
