In the Scientific American of this month, published of course before the dreadful accident in Sydney Harbour. there is an article on a pnysrcal phenomenon known as “Bernoulli's Principle,’’ which may have a significant bearing on the cause of the Tahiti-Greycliffe collision. The article deals with the conditions of water pressure between two adjacent floating masses, and proceeds:— “Dynamically it will be the same whether the boats are moored in a stream or are moving forward side by side, for in ejther case the space between the boats is at reduced pressure. In naval manoeuvres rt is not an unknown accident for the navigating officers to neglect to take such forces into account, whereupon the boats collide." The conditions described appear to be strikingly analagous to those of the recent tragedy, and the article includes a diagram indicating the “draw" of two adjacent vessels proceeding in the same direction..
