I don't think it's intended to be a 'luxury yacht' more a vessel to host trade fairs, summits, etc.
My gut feeling is that trade negotiations are based on what we have to offer a would-be trading partner, and what they want from us - like visa-free travel for some of their citizens. Do we need a ship-with-bunting to conduct these kinds of negotiations? Would it really influence the decisions which are, at heart, 'what's-in-it-for-us'... on both sides?
Johnson is full of self-assured hubris... water cannons, never used and sold for a fraction of their cost; the garden-bridge..
We were a great maritime nation - but is our flag still respected around the world as it once was?
In 2017, Boris Johnson thought there would be "overwhelming support" for a new yacht if private backing could be found. Let the enthusiastic very, very wealthy elite, who believe we can once again be this leading maritime nation, put their money into the project. I don't believe it should come out of the public purse. If it's successful, maybe the nation can then pay for its running and upkeep costs... if we are going to benefit from it.
