Ocean exploration sailing journeys from hundreds of years ago typically required large vessels and large crews (in comparison with today’s space capsules) to travel between the continents and around the world. Modern sailors of today are able to complete similar distant voyages, in small vessels, with a minimal crew, comparable in size to modern space travel crews. This paper uses a systems engineering approach (e.g., using the NASA Human Integration Design Handbook (HIDH), NASA-SP-2010-3407, 2010, and the “Advanced Life Support Baseline Values and Assumptions Document, (BVAD)” NASA-CR-2004-208941, 2004), to examine and compare the logistics and sustainability aspects of a small crew traveling on Earth's oceans in sailing vessels versus humans traveling in space. The “Mālama Honua Worldwide Voyage” of the Hōkūle‘a, a replica of an ancient Hawaiian double hulled sailing canoe, will be used as a baseline minimalist case study. This is a good comparison case since the Polynesian exploration of the vast (and virtually empty) Pacific Ocean with limited resources is an analogue to human space travel. A modern sailboat is compared to the ancient Polynesian methods and then a space craft is assessed with similar functional decomposition methods. In 1992, during his second Space Shuttle mission (STS-52, Columbia), Astronaut Lacy Veach received a radio message from a student: “What are the similarities and differences between canoe and space travel?” Astronaut Charles Lacy Veach answered, “Both are voyages of exploration. Hōkūle‘ a is in the past, Columbia is in the future.” Navigator Nainoa Thompson added from the sailing canoe, “Columbia is the highest achievement of modern technology today, a voyaging canoe was the highest achievement of technology in its day.” This paper is dedicated to the memory of two great Hawaiian astronauts: U.S. Air Force Colonel Charles Lacy Veach and U.S. Air Force Colonel Ellison Onizuka and to legendary waterman and Hōkūle‘a crew member Eddie Aikau who was lost at sea in 1978, at the beginning of a 30-day, 2,500-mile (4,000 km) journey by the Hōkūle‘a to follow the ancient route of the Polynesian migration between the Hawaiian and Tahitian island chains.
