The jetty was to be 15 metres long by 2 metres wide with sturdy handrails on one side. The jetty itself was to be made of seasoned wood and double coated by a waterproof resin cherry brown in colour. It was agreed that the work on the jetty would be finished by 10 December 2007, well in time to celebrate New Year in the sailing yacht with the family. Sonu entered into another contract with Boat Ltd to supply and deliver a 10 metre sailing yacht on 11 December 2007 for a sum of R90,000.Fun Ltd constructed the jetty on time.
