An absolute highlight of the festival! Get involved in our Junk Boat Building Challenge, working in teams to build an amazing craft to sail along the canal. Booking is essential, send us a contact message if you would like to get involved. Saturday is boat building day, using recycled materials to build a strange craft. The race is on Sunday at 1.30 pm when our teams launch their boats and head to Granary Wharf with festival-goers accompanying them along the tow path. But will they float?
