The RNLI launched nearly 1100 rescue missions last year.
The lifeboat organisation rescued over 1200 people in 2015.
Howth Lifeboat station was the busiest with 60 launches, followed by Clifden with 49 missions.
The Lough Ree inshore lifeboat rescued 130 people - the largest number of any of the RNLI crews.
The group says its missions range from the recovery of people drowned at sea, to stranded vessels - and even pets who have gone overboard.
Owen Medland of the RNLI has said people who go out on the water should always think of safety first: “Really the core message that is coming out from the RNLI is we want people to respect the water.
“Whilst we have a beautiful coastline to enjoy it, enjoy it safely, our stations are busy.”
