Inflatable hull structure and method of forming an inflatable boat hull

A method of forming an inflatable boat hull for a boat including a peripheral tube structure having a right side tube and a left side tube which, in an inflated condition, define right and left sides of the boat respectively and each extend along a longitudinal axis of the boat from a stern end of the boat to a bow end of the boat, and meet at the bow end of the boat, the method including:

• (a) arranging two or more bottom tubes side-by-side to form a bottom tube assembly extending laterally in the area between the right side tube and the left side tube;
• (b) connecting a front end of each bottom tube to the peripheral tube structure at the bow end of the boat with each bottom tube also extending rearwardly along the longitudinal axis of the boat to the stern end of the boat;
• (c) connecting the bottom tube assembly at a right side thereof to the right side tube and connecting the bottom tube assembly at a left side thereof to the left side tube;
• and
• (d) inflating each bottom tube to an inflated condition in which at least two or more of the bottom tubes include a front portion which is raised vertically with respect to a back portion of the respective bottom tube at the stern end of the boat.
