While submerged, the U-boat was virtually blind and immobile; boats of this era had limited underwater speed and endurance, and so needed to be in position before an attack took place, while even on the surface their speed (around 15 knots) was less than the cruising speed of most warships and two-thirds that of the most modern dreadnoughts.[7]. War graves on Rathlin recall loss of HMS Viknor.
