I thought it would make a nice hold for a river barge, so sketched out some ideas
I worked out a basic hull shape, made a half piece template and marked out two hull shapes (one for the base and one for the deck)
a section was removed from the deck to provide access to the hold; base and deck fixed to the pen tray
I added sides from thin cardboard...
and made up a removable mast with spars (mast - paintbrush handle, spars - hibachi skewer and cocktail stick)
to show it when docked the hold cover is removed and a stowed sail/mast assembly is used
now have to work out a suitable paint scheme ....
