The Steel Waterwitch drawings were produced by Dick Boelle, a Dutch boatbuilder.  He seems to have got caught up in metricating the design as well as converting it for steel.  This may explain why the lines are incorrect.  He told me that hewas expecting the first builder to loft the lines and record corrected dimensions - of course this never happened!


It is strongly recommended that these drawings are not used directly.  Use the original table of offsets and even then check for errors.  Dimensions of frames etc are almost certainly incorrect.  At least one boat built had a dire profile forward.
