TAKING TOO MUCH WATER OVER FOREDECK.

There are a number of anecdotal reports describing excessive volumes of sea washing over Waratah's foredeck, even in calm weather. I have put this down to Waratah's reduced freeboard and buoyancy factors. If the flow of water onto the foredeck exceeds the rate at which it can drain off, this body of water can cause what is known as a surge effect, shifting the centre of gravity to the respective side and in the case of a list to the same side, increasing that list - which might explain why Waratah sometimes listed even further when hit by a cross sea - surge effect in addition to the force of the waves.
