Need help identifying ring origin - Sailboat

by Justin
(Savannah, GA, USA)

I have a ring in 18K white gold. I am sure it is European based on the 18K 750 marking on the inside of the ring, but there are two other symbols, and I need help identifying them so I can try to find a matching band. The first symbol is to the far left on the inside of the ring. It appears to be an O (perhaps to denote 2013 manufacture date?). The second symbol appears to be a sailboat with two sails. Any help would be appreciated.
