* Geography dictates culture: People living in a chain of islands are naturally going to rely heavily on water travel. The islands are isolated, making land-based travel difficult or impossible.
* Longboats for island hopping: Longboats, with their size and seaworthiness, were ideal for navigating between islands. They could carry people, supplies, and even livestock, making them essential for trade, exploration, and even warfare.
* Examples in history: There are numerous examples of island cultures that developed strong maritime traditions. The Vikings, for instance, were known for their longships and their mastery of the sea. The Polynesians used their canoes to explore and settle vast expanses of the Pacific Ocean.
Therefore, it's highly probable that people living in a chain of islands would develop a culture heavily reliant on longboats.
