It was when Beowulf and Unferth had a conversation. Unferth questions Beowulf’s capabilities when
he mentions the swimming contest that he lost to Brecca. Beowulf counters by saying that he was blown
off by storm and had to fight monsters.
He was making a statement that he was more than prepared to meet and
defeat Grendel.
You didn’t list any of the poems you’ve studied so I can’t be much help, sorry
