The main benefit of this system has been in being able to run an all weather log from our boat, with no limitations placed by water conditions (i.e., waves are not too high or low). This means that we can use it at any time regardless of wind direction etc - perfect for us as its always good when you have some free time! We find most features very easy but would be interested if they could improve their online help section so more people understand how to operate them properly. It was used extensively during last year’s voyage round Britain where there were many stormy days requiring constant monitoring/entry into data base to ensure safety issues weren't overlooked.
