GX42: A 138-Footer That Chooses How It Runs by the Passage Ahead

The GX42 is a new 138-foot superyacht built around a hybrid plant. Its defining feature is that it decides what to draw power from according to the trip in front of it. For an owner, that decision is the heart of the design: this is a yacht meant to cover water economically, with efficiency as the point rather than an afterthought. Matching the power to the passage, instead of running one way for every outing, suits a boat that is meant to be used, whether that's a short hop or a longer run. For readers who measure a season in miles along the Florida coast, it's engineering worth a closer look. The report did not name the yard or the naval architect, and it gave no price.
