Banchor or luckships are a speculative and/or science fictional indigenous Kristang vehicle which move through the fifth dimension of probability instead of the third dimension of space like starships do, and the fourth dimension of time like timeships do, searching for realities that are safe for the Kristang people to inhabit.
Luckships can camouflage as or take any 3D or 4D form (e.g. boat, airship, starship, timeship) but are always characterised by the belamundu or the worlding-sail.
