The proposed ship is about 1,609 metres long and 243 metres wide, giving a length-to-beam ratio of roughly 6.6. That ratio is considered reasonable by one panel member, but it leaves the structural problem unresolved. A hull this long could span several waves at once, imposing different loads along its length. The discussion uses large tankers to illustrate how inadequate allowance for those loads can threaten a ship's structure. Sheltered operating areas, draft, and the hull's construction would affect the result. The panel leaves the feasibility uncertain.

Wave loading on a mile-long seasteading hull
A plausible length-to-beam ratio does not settle how an exceptionally long hull would withstand several waves acting along it.
