The superstructure is forward or midships and the working deck aft. One tank was forward of the midships engine room and the other was aft. There are three toilets, forward, midships, and aft. Each carried one 12-pounder forward-firing gun, two 6-pounders midships and four Maxim guns. Immediately, the minesweeper received continuous hits at the bridge, midships and stern. Two high, slitted steel wind barriers were installed afore the midships and forward elevators. The engine was redesigned to be mounted horizontally, residing midships beneath the load floor. A third elevator midships, in size, was added. Primary strength calculations generally consider the midships cross section of the ship. Only the midships section was left intact.
