Tipping the case gets rid of 80% of the water the rest just spreads out across the Glass which is substantially larger than the waterproof cameras - about the size of a quarter. To be honest I put very little effort into keeping the camera dry, it's just sits under one of the deck rigging bungies (it's to big to fit in a pfd pocket) and with the lens glass cover pointed up it just is a natural spot to collect any water that comes it's way. There is definitely a solution to get by this problem I just haven't found it yet.
