I posted this rec on 3-31-14, which was probably a few days after I read it. it's a Kane/Toews story, though Sid & Geno were a secondary pairing iirc. the author has several other stories still up, and I've no idea why only this one was pulled:

My Lover Stands On Golden Sand by Alexia
Summary: T’was an ill-omened night at sea when a boy walked out of the mists to slay the Morgan’s captain with his bare hands, wrest control from her crew, and lay siege to the seven seas to avenge his lost love.

Or, a boy fell in love with a boy and searched an entire ocean to get him back.

It depends on who’s telling the story.

an absolutely awesome pirate tale, with a possibly magical ship, true love torn asunder and epic adventures along the path to a reunion
