Re: Limits of Captains authority
Jacldale and ChucklesR both have the answer. A Captain's authority follows from his responsibility. Simple as that. Whether you are commissioned, liscensed or not is irrelavent. If you are operating a vessel, yours, rented, borrowed or stolen, you have responsibility for its safe and legal operation, which gives you authority to take legal actions to insure it is so operated.
I also believe in the old Army teaching that you should not order someone to do something you are not willing to do yourself. Willing to, not necessarily capable of.
Captains and crew live in a symbiotic relationship where knowledge, skills and abilities coupled with effective communication and leadership serves the interests of the ship. This thread derives from another - Mutiny at Dawn - where little if any of this was present.
