Be in command of the boat at all times

Coach the crew when the coach is not present

Provide motivation and encouragement to the crew

Provide feedback on the crew's performance both in and out of the races

Make any necessary tactical decisions

Organize and direct the crew at all times, including when putting the boat away etc.

Be responsible for the vessel; in the event of a collision, the coxswain is accountable under maritime law as 'Master of the vessel'
