family awakens to a crisp, beautiful August morning. The temperature is hovering in the low 40s, the sun is shining, and the view out their window is breathtaking. That’s because it’s of the glaciers in Arctic Norway’s Svalbard Islands. And the window? It’s in the salon of their 180-foot Amels Limited Editions, Gene Machine. Who knows what adventure today could bring? They might see a polar bear hunting, or feed a blue whale. A lot is possible in this icy frontier, on their cruise of a lifetime. The yacht and family belong to Jonathan Rothberg, a cruising enthusiast whose love of the water goes way back. “My family has been a boating family since I was a child,” he says, describing their early cruising aboard a 25-footer and, later, chartering bareboats with his brother. In the early 2000s, Rothberg’s parents got a larger yacht: a Princess 76, and then a Westport 112. Rothberg joined the yacht owners’ club himself in 2011 with the first Gene Machine, a Westport 130.
