Launch date for lifting keels

Hello Lifting Crusies
I have been down the see Phil, the deputy harbour master today to talk about launch dates. Current harbourmaster plan is we launch on 31st March. However, I have pointed out that the tidal range is only 0.7m and our launch window is too narrow on that day. I have asked if we could launch on Monday 27th March instead. Phil said he needs to ask James, but did say it seemed a sensible idea. (I’m full of them lol)
One little niggle is that he said James may want to charge the additional 4 days, so we will see where that goes.
I will keep you all posted on progress
I assume moving the date would be agreeable to everyone? Let me know please if any questions
