This phase is sometimes a very dangerous one in amphibious operations both for the crew of the boat and the men coming down the nets, especially when there are high seas. The boats bob about like corks and crash against the APA (Personnel Attack Ship). At one moment the net will be hanging clear of the bottom of the boat and at the next the boat will be raised by a wave so that the net is bunched up and the soldier with all his equipment may get a considerable shoving around.
