CAD/CAE and resin-infusion tech means there's much less oil going in to composites, not like it was prior to 1973 anyway. It all helps lower build costs, improve worker safety and reduce noxious emissions. Resin costs matter, but aren't likely to be as ruinous as it was to the boatbuilders back then, walloped as they were by the double whammy of VAT and OPEC flexing its muscles.Don't forget that GRP is made of oil, which has gone from $20/barrel to $80/barrel this year, so 400% increase.
Same for all plastic goods. Input costs are going through the roof.
