Ireland import cost query

[ljpaddock]

Hi,

I have located a cheap project boat with a non running inboard engine that is located in Ireland. It is being sold by a private individual and I was planning to just get a ferry over, pay in cash and trailer it back on the ferry.
It’s in the £1500-£2000 ballpark so still works out a decent price.

I’m just confused by exactly what import tax etc I would be liable to pay especially post brexit, and how it would be calculated?

Any advice would be appreciated

Thanks
