RAF Castle Archdale was a seaplane base in Northern Ireland. Built in 1940 and in use between 1941 and 1958. I modelled this seaplane base loosely to some aerial photographs I have found and using standard assets of MSFS 2020 so accuracy is not exactly great so please bear (rawrrr) with me in this regard. It is rather to provide some seaplane bases in Europe for our seaplane enthusiasts to start from and to go to. Parking docks are provided so you can start from cold and dark.
If you look for some other seaplane places in Europe, check out my "Blaue Linie" which provides three seaplane ports (Hamburg, Magdeburg, Dresden) along the river Elbe in Germany.
