Cill crest 0 m above chart datum · 0.95 m draft + 0.15 m clearance. When the cill webcam board is legible its reading overrides the tide model and shifts today's window depths by the same offset (board re-read every 5 min). Planning aid — always confirm on the board or webcam.

How This Is Worked Out

  • Cill crest height: 0 m above chart datum (marker board zero)
  • Vessel draft: 0.95 m · safety clearance: 0.15 m
  • Required tide height: 1.10 m above chart datum
  • Model sea level converted using MSL 3.8 m above CD
  • Planning aid only — confirm against official tide tables and the marina
