OK (dinghy)

The OK dinghy is a single-handed sailing dinghy designed by Knud Olsen of Denmark in 1957. It is a popular international class, raced in numerous countries worldwide. The "OK" name is said to derive from Olsen's initials, though some alternative explanations exist.

• Rig: The rig consists of a single mast, boom, and sail. The sail is a single, unrestricted sail area, allowing for experimentation within class rules.
• Sail Area: The maximum sail area is approximately 8.25 square meters.
• Construction: OK dinghies can be constructed from wood, fiberglass, or composite materials.
• Crew: The boat is designed to be sailed by a single person.

Racing and Popularity:

The class has strong international representation and hosts World and European Championships annually. The relatively simple and cost-effective design contributes to its enduring popularity, allowing sailors of varying skill levels to participate and compete. The class rules allow for some freedom in equipment choices, such as sails and fittings, allowing sailors to optimize their boats to suit their sailing style and conditions.
