Hull

The hull is made of plywood.
Some boats has a hull made of Fibreglass.


Interior

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


Rig

The Optimist is equipped with a cat rig. A cat rig (also called an una rig) is simple to manage as there is no standing rigging, often referred to as “unstayed”. With only one sail it can be single-handed quite easily. The downside is its upwind performance.


Keel

DaggerBoard aka Sword

The Optimist is equipped with a daggerboard keel. A daggerboard is a lifting keel that can be lowered and raised, allowing the boat to enter shallow waters as well.

The boat can sail close to the beach as the draft is just 0.10 - 0.20 meter (0.33 - 0.63 ft) dependent of 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 Optimist is about 16 kg/cm, alternatively 92 lbs/inch.
Meaning: if you load 16 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 92 lbs cargo on the boat it will sink 1 inch.
