I doubt there are many members here nerdy enough to care, but in case anyone is wondering, it’s entirely possible to use a SR on a cruise ship. I just got back from a trip to the Bahamas with my family. What a blast! Not wanting to end my streak of shaving exclusively with a straight, I had no choice but to give maritime SR shaving a try. I was concerned about the ship’s motion causing troubles. However, I shaved mostly when we were docked at ports. And when I did end up shaving at sea, I found that the ship’s movement didn’t affect the process that much. The ships are quite large and motion is relatively minimal. I just braced an arm on the wall, winced, and got to it. Anyhow, I survived with no nicks.

…..OK, end of nerd report.
