Built around the middle of the XVIII century from a drawing by Frederik Af Chapman, Gretel is a wonderful example of a pleasure-boat of that time. The interesting plan of sails granted certainly a good speed to the hull. The model we obtained presents no difficulty to curry out. The constructive plans in fact are quite similar to those studied for hulls with bigger sizes. In consideration of the various sorts of wood employed and the richness and elegance of the decorations, the model is fit to be left without any painting.
