Beaufort Scale - Force 10 (Storm Force 10) A storm is a weather phenomenon characterised by strong winds, reaching at least 48 knots (55 miles per hour or 88 kilometres per hour). Storms can also bring heavy rain, rough seas, and turbulent weather conditions. In maritime forecasts, storms are often categorised based on wind speed...

A small, durable triangular sail used on sailing vessels during severe weather conditions to maintain control and stability. A storm jib is an essential piece of heavy-weather sailing equipment designed to provide a manageable and safe sail area when strong winds and rough seas make larger sails impractical or dangerous. Typically made from robust, low-stretch...

A compact cooking appliance or heating device, often found aboard vessels, used for preparing meals or warming the cabin.  The stove primarily refers to a small, often gimballed cooking appliance designed for use aboard boats.
