The Irish Cruising Club publishes updated editions of the indispensable Sailing Directions at regular intervals. Between editions, amendments are available online at no cost. Preserve your investment and stay safe by downloading these amendments – you know it makes sense!
To do the job properly, clear a little quality time to apply the changes. Add some kind of highlight at the location of each change in the physical books, and keep the printed amendment pages at the back.
The first set of amendments for the current editions of both books have just been published:
