Erskine Childers' Asgard, the 1905-built 51ft Colin Archer ketch, is one of the stars of this fascinating book, as her meticulous restoration at Collins Barracks by John Kearon and his team of expert shipwrights drawn from the Arklow tradition has been a fine example of wooden ship conservation.

John Kearon – who is himself from Arklow – is one of the foremost in this field, with a distinguished career centred on the historic ships programme in Liverpool. His patient work, in making Asgard a non-seagoing conserved version of the vessel as she was when Erskine and Molly Childers had her built as a wedding present from her Molly's father, has clarified design features which had been lost in alterations made in the 1930s and the 1960s.

The quality of his research and craftsmanship has also helped in deciding Asgard's future. It is right that she should be conserved rather than restored. But if any group wishes to build a sailing replica, then the definitive plans are now available.

The features on aspects of Asgard's conservation are only part of a very comprehensive extensively illustrated book which covers historic ships and boats of any types. Naturally there's a significant element of serious academic insight. But those of us who are fascinated by all craft immediately warm to a learned volume which, despite its adherence to historical rigour and correctness, nevertheless refers to each vessel as "she".
