RNLI crews on Anglesey were called out 152 times last year, according to new figures.
The total number of launches for the island's four stations was up slightly from 147 in 2024 - with volunteer crews from Trearddur Bay called out 47 times, followed by Beaumaris with 45.
Four lives were saved by crews from Holyhead lifeboat station.
On the mainland, two lives were saved by crews from Porthdinllaen lifeboat station, which came to the aid of ten people.
Across Wales, RNLI lifeboats were launched over 1180 times during 2025 - up from 1048 the year before - and 948 people were rescued with 51 lives saved.
Almost half of all 30 RNLI stations in Wales saw an increase in the number of launches in 2025 compared to 2024.
The figures were released as part of the launch of the RNLI's annual Mayday Mile appeal, encouraging fundraisers to cover a mile a day by any means during the month of May.
