Q:

Crew requirements for sailing a ketch

When sailing a traditional twin mast ketch, what are the recommended crew requirements? 
Let's assume the following for simplicity:

Captain has 6-pack maritime license. 
Captain and passengers total 5 people.
Crew has 1-2 years sailing experience.
Sailing within 20 miles of shore, not in commercial shipping lane.
Boat bow to stern is 45 feet.
Prevailing wind is 10-15 knots, seas 4-5 feet at the bell.
Visibility is 5 nautical miles.

What are the responsibilities of each crew member? 

A:

Every boat is different, and every crew is different. There is no set standard. Some people go single-handed on a ketch, some have fairly large crew. Bernard Moitessier used to sail a 39-foot ketch single-handed and with his wife.
