The ships pooled resources, including food and beer, and developed a system to keep everyone fed during the crisis. In addition to stamps, the sailors created dinnerware and patches to show their association with the GBLA. In 1968, the GBLA ran its own Olympic Games 10 days ahead of the real thing. The crews competed in 14 events, including diving, sprinting, high jump, archery, and water polo. Polish crews even minted medals to hand out at an awards ceremony.
