The meaning of this song. a girl is trapped in a bed because she is to sick to move. her bed is beside the sea, so she is used to seeing barges roaming by. she starts wishing she could get onto one of those barges and sail away from the sickness that was killing her. her mother wrote this song for her, as she died 6 months after she was pronounced very, very ill. her mother was so overcome with grief, she couldnt stop thinking about her, so she wrote this song as a sort of RIP.
