Hull

Both the hull and the deck is made of fibreglass. A hull made of fibreglass requires only a minimum of maintenance during the sailing season.

Rig

The Laser SB3 is built with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a gennaker or a spinnaker for optimal speed.

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 Laser SB3 is about 79 kg/cm, alternatively 443 lbs/inch.
Meaning: if you load 79 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 443 lbs cargo on the boat it will sink 1 inch.
