I think you may be overestimating the precisions with which GDP is calculated. Can you give us a link to the $45B figure?

That's a figure for the entire cruise market, not for goods sold on ships on the high seas.

according to this link , the average spending in 2015 onboard was ~$400, and  23 million travelled by cruise ships in 2015, which gives a figure of atleast 10 billion

How are trades performed on ships at sea factored into GDP calculations?

When a ship is less than $12$ nautical miles from a country's coast, it's in that country's domestic territory, however, on the high seas, it's in the country in which it's registered. So if a sale is made on board, which country's GDP is it included in? How do we account for these sales? The contribution may seem small, but according to 2018 figures, it's a massive industry, with a value of over 45 billion dollars.
