For almost two years, Robert Brewin collected data from the bow of a superyacht as it sailed pristine waters from the Caribbean Sea to the Antarctic Ocean. The Archimedes, a 222foot "adventure" yacht then owned by the late hedge funder James Simons, boasts a gym, a jacuzzi and an elevator. But between 2018 and 2020, Brewin was concerned only with the boat's Sea-Bird Scientific Solar Tracking Aiming System, installed to measure light reflecting off of the water.

A senior lecturer at the UK's University of Exeter, Brewin and his colleagues were analyzing microplankton — microscopic organisms at the base of the marine food chain — by studying the ocean's color. The Sea-Bird's readouts helped them verify satellite imagery. Brewin's was not your typical superyacht itinerary, but he is one of hundreds of scientists to have used an adventure yacht — also known as expedition or explorer yachts — to conduct research on the ocean.

In a paper published in January, Brewin and his co-authors touted the potential of "harnessing superyachts" for science, concluding that "reaching out to wealthy citizen scientists may help fill (research capability) gaps." It's a view shared — and being pushed — by the Yacht Club of Monaco and the Explorers Club, a New York City-based organization focused on exploration and science. In March, the groups co-hosted an environmental symposium that included an awards ceremony for yacht owners who "stand out for their commitment to protecting the mari.
