On my 3rd Morgan, first was a 1981 4 seater, then a 2004 2 seater and now a 2014 2 seater. All have had water on the inside of the windscreen in medium to heavy rain with the hood down and I am suprised that some don't. Depending on the speed simply using the windscreen washers will coat the inside with water. I always have a chamois leather in the side pocket which sorts everything out.
