Ha ha thanks smackdaddy! Yeah its all great fun watching them sweating to remember how to do it, whilst we are pretending to drown. Great fun!
But back on topic there are a multitude of things that you can do to entertain kids.
We had a little
dinghy on the back of ours and we used to time ourselves, how long each of us could go round the yacht with the best time.
You just have to be a little imaginative and everything will fall into place! Kids find everything fun and interesting as long as it is hands on and active (I would know!)
