Jari got a Hero camera which takes still pictures and video and stores them on a memory card. It weighs about 120g and it's watertight, so it's possible to put it on-board and take some pictures while sailing. Seems to work quite well. This could be used later for looking at how the mast bends in different winds and with different shroud and/or spreader positions. (See here for some statistics from the ongoing IOM Euros).
