> It seems extremely unlikely that the technology was gradually and seperately lost on both sides. In this case I'd say it's the exact opposite: on the islands, neighboring communities right on the horizon provided enormous pressure to maintain the ability. Continentals on the other hand have very little incentive. I'd rather say by the time islanders have lost the ability, continentals will most likely have lost it ten times over.
