Scale 1:48. Plan shows the inboard profile and plan view for the dumb mooring vessels YC 112 (1943), YC 345 (1943) [and YC 415 (1943)]. The references YC 112 and YC 345 are written in pencil in the top left corner of the plan and match with the yard numbers printed in the bottom right corner These two vessels were built by Dunston but in 1944 in the yard trading as Henry Scarr Ltd at Hessle, Yorkshire. The number 415 is written in pencil in the top left corner below the other two numbers but in a different hand and no yard number is given for it. No record of any dumb mooring lighter of this design can be traced in any British shipyard and 415 probably does not represent a vessel.
