Scale 1:12. A plan showing the inboard profile, body, longitudinal half-breadth, half-plan view and midships section of an unnamed St Ives gig 'built by William Bryant for the Jonadab, 1910'. It is possible that the name refers to a larger parent vessel, and given the unsavoury nature of the Old Testament character of that name this is the most likely option.

A note on the reverse reads '4 Full size copies to Mr. Dicon Nance; The Court House; Carbis Bay; St Ives Cornwall; 2 Full size copies for Draught room.'

The plan has been signed 'Dicon Nance' and is dated 1975.
