Review of Drabant 21

Both the hull and the deck 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. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with 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.

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.

What is L/B (Length Beam Ratio)?

The l/b ratio for Drabant 21 is 3.08.

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 69

The relative speed performance is 69 which means that a it is faster than 69% of all similar sailboat designs.
