A supplement to the newly published 8th edition of this book is available for download

It has been reported that a yachtsman has been fined for
anchoring in the Portinho de Arrábida in the Rio Sado
without permission. This supplement is published to alert
mariners to this incident and to provide the following
advice:
It is understood that the Portuguese have a maritime law
requiring a vessel to request permission before anchoring in
their territorial waters. Either the local Capitania, or the
Policia Maritima (outside office hours) should be consulted
and they will provide helpful guidance and give permission
as appropriate. In the summer months, when popular
anchorages are busy with boats, this requirement is
normally waived except in sensitive areas.
