Hull

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.

Keel

The boat can enter even shallow marinas as the draft is just about 0.85 - 0.95 meter (2.79 - 3.09 ft) dependent on the load. See immersion rate below.

Sailing characteristics

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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Finn-Dinghy is about 40 kg/cm, alternatively 229 lbs/inch.
Meaning: if you load 40 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 229 lbs cargo on the boat it will sink 1 inch.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Finn-Dinghy is 2.98.

Compared with other similar dinghies it is slimmer than 85% of all other designs. It seems that the designer has chosen a significantly more speedy hull design.
