Not random... and not for bracing purposes. Built this way as new. When you see the whole length of the overhang then it becomes a bit obvious. There are pairs of 'brackets' are to prevent the lifeboats from being caught under the overhang when lowering... or raising. The first boat position was originally a different type of boat.... like a launch with engine and a cabin.... fitted with wireless as well. These brackets were need to keep the boat from keeping caught under the overhang.
