Star Trek: The Cruise, a convention at sea that’s been running annually for the last few years, has announced today that Star Trek: Discovery‘s Jason Isaacs is boarding the cruise next year, expanding the Discovery representation on the oceanic event for 2019.

Joining Isaacs from the new series is Wilson Cruz (Hugh Culber) and Mary Chieffo (L’Rell), all three continuing their Trek fandom journeys which include appearances at STLV 2018 in Las Vegas this August, as well as traveling abroad to the UK and Germany for conventions in Europe later this year.

Another notable appearance on the 2019 cruise, scheduled for next January, is Next Generation actor Wil Wheaton, who while often appears at genre cons throughout the country, is a rare sight at an official Star Trek convention (likely due to his less-then-pleasant history with STLV organizer Creation Entertainment). His inclusion in the 2019 cruise roster is something that is certainly nice to see, bringing him back into the fold for a Trek-specific event.

Aside from Wheaton and the Discovery cast, the 2019 cruise lineup has expanded to 18 cast members so far, including TNG’s Jonathan Frakes and Marina Sirtis, DS9’s Nana Visitor and Rene Auberjonois, VOY’s Ethan Phillips and Robert Picardo, ENT’s Connor Trinneer, and several more.
