The Principal’s decision is final at all times, on the property and the vessels of C-MASTERS, until the Skipper takes over. From the moment the Skipper steps onboard the vessel in accordance with marine practice, the Skipper’s decisions are final always. All crew will accept all orders and decisions given to them by the Skipper at all times whilst onboard the C-MASTERS vessel or ashore, for the duration of the course until the course is complete and the Skipper is no longer onboard the vessel.
