Dear Sandy, they are most difficult to control indeed! They take a lot of practice before you master them and then like a lot of things very easy and safe! however when you are learning be prepared to get very wet.
I am used to getting very wet and yes I can and have used a coracle. They are much loved by hunters and camera men/women as they are almost silent, and are so light can be carried on your back!
You should have some fun in one some time, and try getting wet.
Neil.
