Steamer

Dear colleagues,

I am ex officer working on commercial ships at sea and later as operations manager ashore.
I am invited now by the yacht Owner for the interview to fill in open position of a Captain on his 26 meters boat.

Can anybody, please, guide me on main differences working on Yacht if to compare with Commercial Vessel on some matters, like :

1/ Employment Contract - Qualification documents (Deep Sea Navigator Diploma - Travel documents (Seamen's Discharge Book?);
2/ Arrivals/Departures - Customs/Immigrations procedures;
3/ Bunkering / Yacht supply / ...;
4/ Using of Shipping (Yacht?) Agency services;

"Funny thing" is I do not know yet if the boat is registered for a Company or a private person as well as if she is registered under any any recognized class.

Understand, however, that she is Company Owned, then overal position is that the vessel is operated in the way more similar to commercial vessel operations (?)

Regardless of above questions I would be thankful to Your any GUIDLINES on what to discuss / start with when my person will be found acceptable.

Thanks indeed Your assistance !
