They are handy, lightweight, intuitive to use, have low energy consumption and can be used universally thanks to inexpensive software. Tablet computers, especially Apple's iPad, have spread rapidly on yachts. This is despite the fact that, unlike conventional marine electronics, these multimedia devices are not weather or water resistant.
Unprotected, however, even the first use in the cockpit can mean the end of the flat computer. This is because water, especially salty water, is the natural enemy of all electrical and electronic equipment.
The only remedy is proper packaging. At first glance, the range of protective covers and cases seems overwhelming. Whether in specialised shops, online shops or coffee roasters, plastic covers are available practically everywhere. However, these normally only protect against scratches or knocks. If you are specifically looking for waterproof models, there are only a few suppliers left.
However, these come with an even wider price range. The cheapest bag costs just 25 euros, while a case is available for just under twice that amount. However, you can also invest over 330 euros in a rigid protective armour. You can find out which solution is most practical on board and exactly what the differences are in YACHT 16/2012, on newsstands from 18 July.
