We draw 4' and we went hard aground on Heigham Sound whilst participating in the 2012 TRR we were not able to get off without using the engine and disqualifying ourselves but since the dredging we have not had a problem there or in getting up to Horsey. We transit most of the Broads network and the only No Go areas in the main Broads network for us are Catfield Dyke, Coltishall to Horstead Lock and West Somerton. It gets a bit interesting on the upper Ant to Dilham and at Gelderston.
When sailing you get to know where the shallow areas are but occasionally you hit something you are not expecting
