RV Celtic Voyager is a multi-purpose research vessel operated by Qikiqtaaluk Corporation as of 2023.

It was Ireland's first custom-built multi-purpose research vessel, replacing the repurposed fishing trawler RV Lough Beltra.

[1] Celtic Voyager was constructed by Scheepswerf Visser in Den Helder, Netherlands, being delivered in July 1997.

While it had much greater capabilities, its range only reached 20% of Ireland's 220 million-acre sea territory.

[5] In its 25 year service with the Marine Institute, the vessel completed more than 600 surveys, enabled more than 6,500 science days, and sailed more than 550,000 miles (890,000 km).
