• A SpaceX Starlink user strapped the internet dish to a yacht on a trip around the Greek islands.

• He was testing Starlink at sea for his company RebelRoam, which provides WiFi for public transport.

• He told Insider that Starlink's connectivity was "surprisingly good" despite some outages.

Starlink, SpaceX's satellite internet service, is becoming increasingly popular across the world — so much so that some users have even taken it on vacation.

One user told Insider that he strapped the Starlink equipment to a yacht and sailed around the Greek islands for a week to test how the service fared at sea.

Tarvo Topolev is the cofounder of RebelRoam, an Estonian company that provides passenger WiFi on public transport such as buses, trains and cruise ships. He said he ordered Starlink in July and received the kit, comprising a dish, WiFi router, and a tripod, a week later.

Topolev opted for Starlink's RV package, costing about $600, because RebelRoam wanted to test its service in different locations.

As part of a team event, Topolev said nine employees, including himself, traveled with the Starlink kit to Athens.

They then hopped on a yacht, attached the Starlink dish to a pole and sailed between the islands of Kea, Mykonos, Syros, and Kythnos, testing the network for a week.

They combined Starlink's service with cellular connectivity and compared the two while using social media, Google maps, and video streaming. The outcome? Starlink and cellular complimented each other, according to Topolev.

Starlink suffered outages when it was surrounded by other boats' masts or when the yacht made sharp turns, but worked well at sea, whereas cellular connectivity dropped out when the boat was far from the shore, Topolev said.

"It was surprisingly good," he said. "There were some outages and sometimes we had to manually reboot it ... but basically it worked ... almost all the time."

Topolev said cruise ships use a combination of WiFi and cellular to provide internet connection, meaning Starlink would be a useful and much cheaper option.
