Weekender is a 2c/7 orthogonal spaceship that was found by David Eppstein on January 12, 2000.[1] On April 27, 2000, Stephen Silver found a tagalong for a pair of weekenders (shown below). At present, n weekenders pulling n-1 tagalongs constitute the only known spaceships with speed 2c/7. These were the only known period-7 spaceships until the discovery of lobster in 2011.
