Yes Madge was built by Simon as a practice project before building Cheese Before Bedtime. It is foam, polyester and glass. Carbon space frame was laminated with epoxy though. Will Perrett gave Simon a financial contribution and nievely expected a finnished boat. Simon, understandably did the minimum possible. As a result some detailed finnishing just didn't happen. I recal Will moaning that Simon hadn't reinforced the edges of some side tank cut outs. I replied, that's because he thought you could do those bits, what do you expect for 500 quid? (Including materials!). Will always liked his boat numbers to end in "6". Hence Madge being 2646 even though it was built before Cheese - 2645.
