The data that is currently available supports the assertion that Americans currently own the largest percentage of superyachts worldwide. The claim that Americans are currently the leading owners of superyachts is supported by reports cited in the article, which show that American owners own 23 percent of all superyachts over 40 meters, by far the largest national share, while Russian owners own only 7 percent (Kaysen). This is supported by external industry sources. For instance, according to the SuperYacht Times report, the United States owns about 23% of all large yachts.
The article's argument that the ultra-rich, especially the top 0.1 percent of American households, have amassed enormous wealth, making it easier for them to enter the superyacht market, is also supported by the growing wealth in the United States. Without access to the original New York Times data, I was unable to independently confirm the precise "$23.3 trillion" figure; however, the overall trend of increasing American wealth concentration aligns with other analyses of the superyacht market.
Lastly, experts cited in more extensive industry reporting concur that the market now "depends" significantly on U.S. consumers. Numerous market reports acknowledge the ownership shift away from traditional strongholds (like Russia) and toward America, indicating that the article's conclusion is based on real trends rather than being overblown.
