Note: Navigators should be aware that as at June 2022 the Navionics charts are NOT necessarily up to date. There has been considerable silting of the swatchway on the south side resulting in vessels grounding in an area shown as 6M deep .Navigators should keep a close eye on depths when transiting the channel.
Roger has been involved in taking soundings & notified the chartists, and these soundings have been included below.
From speaking to vessels passing the area it would seem that Roger’s new waypoints are in safe water & are ,therefore, shown in the enclosed chartletSW Sunk 2022 V1
