Southern Cross - Crosby Stills & Nash
The River - Garth Brooks
The Reach - Dan Fogelberg
Leviathan - Schooner Fare
Piranha Potluck - Eileen Quinn

Possibly Four Strong Winds, Scooner Fare or others, not entirely sailing related but a pretty song

PS Have to disagree with Larry a bit, I'm not a huge Buffett fan but a few of his songs have very pretty lyrics
