Please Help me identify this boat!

I am really struggling to identify this boat of mine, any suggestions would be brilliant. We originally thought it was a seawych but this was not correct, The name of the boat is The Sea Apollo which we think may have a tie with the originality of the boat. A brass plaque inside the cabin reads (translated form Hungarian) Built in the BalatonFured MHD's dockyard Hungary (Lake balaton Near Budapest) 1969 Number of construction 64. On the cabin door is a THPA 1986 sticker on a steel plate with 7351 on it. I Think it has spent the last 10 years at Alnmouth Northumberland/ Newton by the Sea and previously North Yorkshire with a owner called N. Ring or Rug. The rudder is through the deck not hung on the transom.
