Yes but there has been recent upgrades to the port for large ships. From what I understand they will move shipping to cork city to here and the city port is due to be developed/sold.Ringaskiddy has been used by Grimaldi RoRo's for years. There is also a twice weekly scheduled service to Zeebrugge and so this could be used by Tesla in the future.
I can't see Tesla charters from Shanghai stopping here unless the shipment is 500 +. We have seen ships continue on from Zeebrugge to Amsterdam and Norwegian ports when demand dictates it, but the numbers need to be big.
No doubt Brexit driven too better connections to France.
But yes thats my point paltry 800+ cars a year to Ireland from tesla there is demand but no service.
Lot have orders open from August/September.
Logistics and cost from Zeabrugge is never going to feasible for large numbers either.
