sometimes nighttime camera fail is good?

Last night we went on a boat cruise (the sailboat kind) of the Boston Harbor - at sunset!  The views were lovely...and as I am still familiarizing myself with all the buttons on my camera, I did not find the nighttime landscape mode until about five minutes before we were going to dock.  The resulting squiggle light lines were kind of interesting, though.

Rather dizzying too, I think.
