I intend sailing this Wednesday June 2nd. I'll leave Queen Anne's battery and motor out to South Mallard buoy for 10.30am departure.
I'll head out past the west end of the breakwater up to the Knap buoy before swinging east towards West Tinker buoy. Then I'll head north to the eastern end of the breakwater, up to the Duke buoy and back to where I started at South Mallard. Its 6 NM.
The weather is predicted Force 2/3, from north west...sunny with odd cloud and temp around 19 Celsius. Visibility is good and sea state slight.
I should be on a beam reach/training run for the outward leg; from Knap to West Tinker it should be a downwind run before turning onto a close haul run back to port........I think......if my visualisation is right! Now whether this is the right way around to do this route.......or not...... I have no idea. If anyone knows better.......please let me know before Wednesday!
High tide is at 9.45am - 4.9m falling to 1.7m at low tide (so the tidal range is 3.2m if my maths is correct....and that's a BIG if!). It's an outgoing tide, with low tide at 16.04. The tidal stream according to the tidal diamonds is negligible for first two hours on outgoing tide. However, on the close haul from east breakwater back up to Mounbatten - there is a 1 kt tidal stream running 171 degreeM - so against me - so that will affect my progress northwards. I think I will be averaging 3 knts so on this leg I'll drop to 2 knts.
Dead reckoning suggests I should do 6NM at 3 kts in 2hrs. So my ETA back at South Mallard should be around 12.30pm. However, when I take into account the tidal stream then it will be around 12.45 ish.
I've marked the route on the chart using the conventional symbols; I've also worked out the magnetic bearing, distance and dead reckoning time between each buoy. I've entered them as waypoints in my GPS and I've created a route ready for Wednesday. I'm slightly panicky that I've got my latitude and longitude reading off the chart scales wrong. I'm OK at say N50d 20'....its then getting the end bit right......um!
I printed off a passage plan and sealed it into a clear plastic wallet which I can now write over the top of in chinagraph pencil - a perfect re-useable passage plan framework. I've also taken the precaution of sketching out annotated diagrams on how to pick up moorings/leave moorings under sail etc and I've taped them into another clear plastic wallet.
