Level 2 Certificate Assessing conditions – wind & tide Direction of the course for training will depend on wind and tide conditions. Wind and tide together give a flatter sea. Wind against tide creates a "short" confused sea. The stronger the wind and tide, the rougher the sea. The first leg should go into the wind and return with wind and tide. 7
