Sophie

Sophie is main character. She is adventurous, kind, and passionate about the sea. She's curious about everything and asks questions about every single detail about everything. Sophie knows a lot about boats and knows what she's doing when she helps around the boat, even though Brian and Uncle Stew bring her down about it. 

Once Sophie has made up her mind she will stick to it. No one can tell her otherwise. Sophie wants to visit her grandfather, Bompie, in England and sail across the ocean. Along the trip, she tells stories about Bompie. She makes them so detailed it's like you were there when it was happening. Sophie does get her memories mixed up some times, but they all become clear at the end.
