Doors opened at 11am and the volunteer lifeboat crew was on hand to give tours of the station and its two lifeboats.
Activities included face painting and a joint display by Wicklow Fire and Ambulance Services. Garda, Customs and Civil Defence also put on displays throughout the afternoon, while the Irish Coast Guard helicopter flew over with the winch crew waving to the crowd below.
The final display was a simulated call-out of the inshore lifeboat. The three crew members onboard demonstrated how fast they could get into their lifeboat gear and launch.
The planned exercise involved a rescue to an injured sailor from a boat which was located in front of the crowd. The crew handed him over to a waiting ambulance.
Folk group Sheringham Shantymen travelled from Norfolk for the open day to see the station's inshore boat, which the group funded and which was named in their honour at a ceremony in 2007.
The Shantymen entertained the crowd with music and concluded the open day with a rendition of the lifeboat anthem, Home From The Sea.
Speaking after the event, Wicklow RNLI volunteer lifeboat press officer Tommy Dover said: "We have had a fantastic weekend with the Sheringham Shantymen. One of the highlights was the concert on Saturday night where the crew was invited to join the group on stage to sing Home From the Sea.
"The crew has a long association with the Shantymen and the lifeboat they funded has rescued 32 people to date at Wicklow."
Meanwhile, a successful sea safety roadshow was held at Sligo Bay RNLI during the weekend's Sea Shanty Festival.
Numerous lifejackets were checked with many having various faults such as corded cylinder, loose cylinder or out of date firing heads. Many people also sought advice about flares, anchors and VHF radios.
RNLI Sea Safety Roadshow adviser Joe Morr said: "It was a very successful weekend in Rosses Point and I hope to bring the roadshow back again next year."
