funfinn2000...your maths is out.
So, Co-Pilot scales are OK are they?
GHC pays $60000 (about £37000 at todays rates) for working 2/3 of a year. So if you add a quarter(ish) to account for tax that means you get about £46000, over two thirds of a year (35 weeks), which means you are paid about £1300/week.
North Sea operators pay £45000 - £60000 for half a year (equal time rosters). North Sea range is about £1700 to £2300/week.
GHC Captains obviously win IF they are being paid three times the Co-Pilot salary.
