What do you think of...
...Lady or Princess and the name of your wife or the name of your daughter?
I like the names "Bibi" or "a little liberty". A sportfisher is a fast boat... "Sayonara", "Ciao" or "The Flying D"
The initials of your family: You. your wife. son. daughter. Or play a little bit with the initials to get a word.
By the way, my little boat is called "Seahawk" like the US-NAVY ship
