Ask for help crossing the lake

You ask the men for help getting to the other side of the lake, vaguely explaining you're on a quest of some variety.

The lead man gifts you a dazzling grin, "Of course! We know this old lake like the back of our hands, don't we, boys?" The other men make sounds of affirmation, "We'd be happy to swim you across once we're done resting up ourselves." His face turns concerned, "We'd love to have you join us in the meantime. You just look so tired. Why don't you just hop on in?" He gestures at the, admittedly, very refreshing-looking water. The walk here was pretty exhausting.
