Dozens of people were rescued from difficulty off Lough Derg in 2014.
New figures released by the RNLI show they had 18 inshore lifeboat launches last year with a total of 43 men, women and children brought to safety.
Lough Ree was the busiest life station and overall 1,400 people were rescued by the RNLI which is urging people to think ahead and never underestimate the power of the sea and inland waters.
There was a 10 percent increase in the number of people brought to safety by RNLI crews.
Part of the reason was the great summer weather, which caused more people to go to beaches and lakes, and out on pleasure craft.
