問：「行舟船上得結界不？」答：「得。若有沙彌白衣驅著岸上，然後結界。若不驅出，當障隔著一處，然後結界。結界後，比丘夜不持衣不得入水中。」

Question: "May one demarcate a sīmā on a sailing boat?" Answer: "One may. If there are novice monks (śrāmaṇeras) or laypersons, expel them to the shore, and only then demarcate the sīmā. If they are not expelled, one must screen and isolate them in one place, and only then demarcate the sīmā. After demarcating the sīmā, a bhikṣu who does not hold his robes at night must not enter the water."
