Scale 1:24. Plan showing the body plan, sheer lines, and longitudinal half-breadth for a single-masted 30 ton sand barge used in the river Tanner. The plan includes notes of scantlings of a typical sand barge, with scantlings noted as taken on 20 May 1760. the barge was fitted with a single mast, boom, and derrick.

Possibly, the River Tanner referred to in the inscription (below) is in the USA, now the River Lafayette.
