Scotia's new roster which starts on Oct 10 is 7 on 7 off but they have specifically stated it is not a commuting roster. Don't know how they will police that though.
The guys based on the 40's do 14 days on 14 days off and a few of them live in sunny Spain. If you have a Dauphin rating and will live on a rust bucket scattered with aspestos (recent allegation) I am sure someone will bite your hand off.
I am just a lowly cojo though so that is speculation not a job offer.
