For what this is worth, the RORO, NOCC Caspian left Yokohama around the 12th of April and arrived in Vancouver, Wa today. I also found this on a site listing Columbia River ship traffic: "
NOCC CASPIAN – TACOMA TO VANCOUVER – SUBARUS (AST~5:30PM/VANC~11:30PM) "
This does not mean there are BRZs on the ship, but it is carrying Subarus.
