LLoyd's classification and class notations

On the purpose of class notations, the definitions given in 2.1.1 to 2.1.11 will apply.
2.1.1. Clear water. Water having sufficient depth to permit the normal development of wind generated waves.
2.1.2. Fetch. The extent of clear water across which a wind has blown before reaching the ship.

2.1.3. Sheltered water. Water where the fetch is six nautical miles or less.
2.1.4. Reasonable weather. Wind strengths of force six or less in the Beaufort scale, associated with sea states
sufficiently moderate to ensure that green water is taken on board the ship’s deck at infrequent intervals only or not at
all.
