More drawings done with Google Sketchup - now in glorious colour.
First how the proposed cratch table should look when folded.
Then three views of the inside of the boat. I modelled this up by eye, i.e. without any measurements and working entirely from memory, so the proportions may well not be too accurate, but it is recognisably Herbie. I guess for those who have never seen her, this gives you a reasonable idea of the accommodation.
