Time of last Avalon - LB ferry in spring?

[ChrisM]

I am looking to go to Avalon late April, but have an event on the Sunday at Two Harbors, I am not yet sure what the logistics are for getting us back to Avalon on Sunday. The schedule only goes thru March 31 at the moment, does anyone recall or know what time the last ferry departs Avalon for LB? (assuming LB would be the latest)

I also see an early evening ferry from TH to LB via Avalon

Thanks
