Many elements affect sailing so it is important to know what to expect before you get on the water. Factors to bear in mind are:
Most associated with sailing and particularly important to competitive sailors who seek accurate forecasts so they can plan their strategy and tactics prior to a race.
If wind speed is too low it is very difficult to sail at all but if too high then there is a danger of broken equipment on board, collisions, accidents and capsizing.
The type of waves and their swell will have different impacts on boat and sailor. High waves/swell can swamp boats potentially causing damage to both person and boat.
Weather conditions can change frequently at sea so as well as your buoyancy aid it is important to consider what you wear. For dinghy sailors, it may be necessary to wear a wet or dry suit.
Ensure your boat is appropriately equipped (paddles, bailing dishes, anchors etc) and that all participants wear well-fitting buoyancy aids. It is important to remember that most authorities require a safety boat that is sufficient for the number of passengers is present.
