The Great Harbour Book

The Great Harbour Book-series is made by the sea scout group Turun Partio-Sissit with decades of seafaring experience. We visit service-, and natural harbours around the Baltic sea collecting sounding data and local information. We use the resulting data of this work to create harbour books for different areas. The charts are drawn by us using a variety of sources and the approaching routes are designed based on our own soundings. The books are made by volunteers and their profit is used to developing sea scout activities.  

The great harbour book is dealt in four areas

The great harbour book I – Turku archipelago
The great harbour book II – Åland islands 
The great harbour book III – The gulf of Finland
The great harbour book – bay of bothnia
In addition to the harbour books we also publish logbooks and the great route guide
