Describes the construction by Marine Archaeological Surveys (MAS) of a replica of the Clapton, Hackney, logboat. A suitable oak, retrieved from the October 1987 storm, was worked with tools of late Saxon type, recording each stage. The unskilled team took about 300 hours. The boat holds four adults in still water; handling trials are planned and other work of MAS, eg., on locating wrecks, is outlined.
