Hi Richard and welcome to the forum.
You could do a lot worse than buying a copy of "Model Boats" magazine (about 6 GBP). The main suppliers advertise in there and should be able to advise you….
Also, the plans service, 'Sarik Hobbies' will list a variety of options often with a guidance for beginners. Some of their designs have a wood pack /kit that is also available. (Beware, balsa prices are sky-rocketing at the moment !).
Good hunting, and if you are stuck for ideas, come back to us.
Dave
ps just spotted a "Penn Duik" kit for sale on Ebay. It doesn't look to me like a 'beginner' class model though…
