In what way is the theme in this excerpt from "the lady of shalott" by alfred, lord tennyson similar to the theme of the poem "ulysses"?

down she came and found a boat
beneath a willow left afloat,
and round about the prow she wrote
the lady of shalott.

and down the river's dim expanse
like some bold seër in a trance,
seeing all his own mischance--
with a glassy countenance
did she look to camelot.
and at the closing of the day
she loosed the chain, and down she lay;
the broad stream bore her far away,
the lady of shalott.

both poems explore the idea of pursuing new experiences.
both poems reflect on issues of isolation from society.
both poems use images of water and boats to represent the unknown.
both poems warn against the dangers of embarking on a new journey.
