The Oyster 495 is the smallest model in the Oyster Yachts range. It is also the first model designed since the yard was acquired by Richard Hadida in 2018. First example afloat in 2022, it was named European Yacht of the Year 2023 in the Luxury Cruiser category.

Built in Wroxham (Norfolk, UK), Oyster’s historic site relaunched in 2018 after the yard’s restart under Hadida.
