I tried some of these for harbours around Ireland and the South coast of England and found many needed updating and relied on feedback from users.
I preferred to use pilot books and make my own notes.
Obviously I learnt navigation the 'old' way and enjoy doing my own chart work and use a simple Garmin 72 to confirm.
I confess to getting caught out by my own stupidity with the Garmin when crossing the Meridian line, I forgot to enter Eastings instead of Westings, DUH !
Each man to their own choice so they may work sufficiently well for you.
