It depends on which word is underlined.
If the underlined word is <em>boat, </em>then it is used as A. predicate nominative in this sentence.
A predicate nominative is a noun following a copulative/linking verb.
The linking verb in this sentence is <em>is, </em>and the noun following it is <em>boat. </em>
