My mate bought a boat last year - a Colvic 22 - a very traditional chug-chug type motorboat - and the previous owner had been a merchant seaman who had spent a lot of years working up and down the coast of Morocco. He called the boat
"The Barbary Coast".
The boat is the least "Barbary Coast" boat out there. It would have to be an arrow shaped black powerboat.

Pole Star - although this one can have a very different connotation these days
Orion
Cassiopeia - a constellation and a queen from Greek mythology
Similarly - Compass Rose
Back to nature and the river
Kingfisher
