I’d really encourage you to continue building your Katie, it does make a great model and you’d made such a good start. Including an auxiliary motor which was looking good. I’m sorry that my posting has had a negative influence, as I’m far from an experienced model maker.
My model is far from “display” quality and is made to sail, which i feel is the important aspect to any model. The conditions at Fleetwood can get “lumpy”.
There is considerable pleasure is making and then actually sailing a boat. Please keep going, there is a need for more sailing boats being built. It’s an aspect that seems to be ignored by Model Boats magazine.
