Hakone sightseeing cruise hours?

Hi,
What are the operating hours of the Hakone sightseeing cruise? I'm going to use it around 4:30pm-6pm from Hakone machi to Togendai where my hotel is. Is there a timetable too?

Thanks.

Here are some links. The second one has a timetable of sorts (at least operating hours).

Figure it stops about one hr. before the sunset. The rope way, too.
If you missed, there are buses run later ~8pm with a few routes but best to go to Miyanoshita and pick up the direct bus to Togendai~9pm..
