Thank you gents for your suggestions but it's neither of those designs. From memory it's a modern day designer and he does have a quite a number...
Still hoping somebody will recognize this design...
Ages ago i found this boat on the net and saved the picture but now can't remember who was it designed by. I think it's called 'Simplicity' and it...
Found it: Phil Bolger Bantam.
... i found it in one of the threads and now i can't find the thread. Thanks. Tom
