Lightning on Tamaki River

The following photo is, I think, from that Friday thundershower, and has been sent in by Steve Sinclair . Orsum.




Our Cruise director Ross Davenport researched the weather and tides and picked Woody Bay for our 2015 Summer Cruise—it was certainly a popular spot on the evening of Saturday 21st February.

It rained over the Auckland isthmus on Saturday afternoon but remained dry at Woody Bay.  Smile  Good planning.

Stephen Plank’s photo record is now available at CANANZ Summer Cruise (55 images and 1 video)

There was a wind from north by northwest, good enough for sailing, and it did bring a gentle roll into parts of the bay.


The first CANANZ yacht to arrive was MOKOIA (Our Patron Jim and Karin Lott’s “home “boat), followed by the Plank family on CLOSE ENCOUNTERS, Treasurer Basil and President Bob on PINK CADILLAC, The Davenports on SAN FRAN, and then  Liz and Chris Fotherby on SOUTHERN VENTURE.




Around the time of low tide  (4:06pm, 0.2m) we all made way to the beach which then had ample room for our gumboot throwing contest.


The winner of the MAGGIE TROPHY this time was Stephen Plank, just beating a wonderful throw given earlier by his son Cullum.








The new moon on Thursday 19 February was very close to this month’s perigee (shown on  graph below)  and thus we had a king tide on the 21st.   It was fun watching the tide come in, requiring us to put our BBQs further up the beach. Timing was just right and by the time we were forced back to our boats, there was only around half-an-hour of light left.

In Hauraki gulf the high tide at 10:29pm sat 21st was 3.6m ,

and at 10:56am on Sunday 22nd it was 3.7m, about as high as it gets unless we add a storm surge (SS)

Yes, SAN FRAN and  CLOSE ENCOUNTERS rafted up for a party during the evening. Quantum biology was part of the discussion.

On Sunday morning all 13 of us gathered on MOKOIA for a collective breakfast at 9am. We forgot to record the delicious offerings, including the dozen cup cakes covered in chocolate icing made for us by Olivia. The various boats then made off in different directions to enjoy the light winds and various delights that Sunday offered.


For the technically minded here is a graph of the wind speed and direction at Bean Rock during the weekend:
