I am Sad to say this, but it would have to be Oil
. And no it's not just the fact we would have no fuel
or lubrication. Besides, there are enough alternatives for those purposes.
But without Oil
, most of the synthetics for cloths and thus the new sail technology wouldn't exist, along with many of the new technology ropes that have tremendouse strength and nice to handle.
Resins wouldn't exist, so we wouldn't have glassfibre boats and a lot of the water
resistant and super strong glues and fillers would be gone.
We wouldn't have the specialist paints, so Steel
boats would be harder to keep rust free.
No plastics for Instruments, so they would be the old heavey metal cases. The list goes on and on. There are very few products that we use today, that are not in someway totaly reliant on the existance of oil, to exist themselves.
