In preparation for the new shipping trade to the Wallasea Wild Coast project, Crouch Harbour Authority, with support and assistance from Crossrail, has carried out out major improvements to the buoyage of the River Crouch approach channels from Whitaker Spit inwards to Burnham Fairway.  There is a printed version in October 2011 On Watch.  For most up to date information go to the Crouch Harbour Authority website.
