A basic requirement of every sea pilot is reliability. As pilot aspirant - so called "trainee of pilot" only experienced captains or very experienced senior officers, which served many years at sea are authorized. In this profession the safety and efficiency of navigation at the seawater streets has the highest priority. The advice of the pilot is asked particularly in difficult and narrow fairways. He guides the ship safe due to his precise local knowledge, gained over time in his career experiences through all shoals and dangers. He helps the captain, with his ship - even under extreme weather conditions such as fog, blowing snow, storm and ice - safely to reach his destination. But he never takes over (with the exception of the Panama Canal) the command of the ship. Sea pilots are in all weather condition in service - at day and also at night time. The pilot remains on board until the ship has reached its destination . That makes this job very interesting but also very demanding.
