What is the effect of a captain borrowing money at the owners' residence?

When a captain borrows money at the owners' residence, the transaction primarily impacts the captain's personal liabilities rather than the ownership stakes associated with the vessel itself. This means that any debt incurred by the captain in this context would normally be considered a personal obligation, and as such, it typically would not directly affect the financial interests or ownership stakes of the other owners of the vessel.

Owners of the vessel generally have limited liability for the debts incurred by the captain, provided that the borrowing is not authorized by them and is outside the scope of the captain's authority as an agent of the owners. Therefore, the correct answer reflects that only the captain's share or liability is implicated by such borrowing, isolating financial responsibility to the captain rather than overlaying it onto the ownership of the vessel.

In this case, the other options lack correctness because they either suggest a collective liability that does not exist or assert conditions (like the need for owner's approval) that would not apply to a personal loan taken by the captain without explicit consent from the owners.
