In the early 60's I used to have a holiday in Groomsport Northern Ireland, my grandmother owned a (this is what I was told) MTB boat called Sabrina. I was told that the name was kept the same as it was when built. It was converted into a house boat and was moored in Groomsport NI for a few years and then scraped in the mid-late 60's. 

I am wondering if anyone knows the history of this boat as I would love to find out for my mother.

This is all I know for now, I will ask more relatives

Any Help would be good.
