I’m going to do a write-up of my recent swims but here a bit more detail on yesterday’s effort (from a msg to friends & family last night): A few hours ago I finished swimming Kawau Island to Tiri Tiri Matangi Island, off Auckland’s Hauraki Gulf. It was much tougher than expected especially into the wind for last 2hrs. Took 7hrs 35 mins which was about 2hrs longer than I planned. Straight line distance was 16.5km but tracker shows I covered closer to 18.5km. My previous longest swim was 10km in 3:30hrs 12 days earlier. So this was well over 2x duration and ~1.85x distance. A bigger jump than I planned. I considered giving up several times in the last 2hrs and only my support crew kept me motivated. After all it was purely a personal challenge not a competition, so I was swimming alone. So the last 2hrs became a mental battle with myself, as much as a physical battle. Anyway, looking forward to a beer & steak for dinner! Only just read this.. wow what a massive effort! Well done. Certainly good to set challenging goals for ourselves. Any other crazy/epic swims planned? |

Go on "Fogg" do the big swim from Ponui Island to Coromandel.Its only 12 miles acroos. Was out there on Sunday and plenty plenty of sharks some small some not so small,do not know they type but when at a good estimate from distance. Dorsal fin to tail appeared no smaller than about 1.5m. plenty cruising different directions. But you would be safe with small pods of Dolphins around,Saw several groups of 6. male v female??

The Firth has always been full of sharks. Our son was in Man O War Bay the weekend before Xmas and was scrubbing the duck board when a 2m Bronzy cruises up beside him. Reckons he could have reached out and patted it on the back. We were down there with him on Boxing day. Son in law, son and 2 grand kids swimming of the back of the boat, get out of the water to get changed and a bloody shark jumps out of the water directly behind the boat.

Any other crazy/epic swims planned? I’m contemplating Little Barrier to Kawau (or the other direction depending on winds & tides). Hence my question. I’d have quite like to do Great Barrier to Little Barrier but it’s not far enough any more. |

A guy I did a passage with had swum from Cape Colville to somewhere south of Tryphena some years ago.
Not publicised, only heard about it at his funeral.

It is the breeding ground for Hammerheads,thresher . The sharks we saw werent cruising but actively hunting. Woke a couple up on the way over at 5.30am Plenty of Kahawai schooling |

The tidal charts from CZ / SJB have been great for the inner gulf. But now I’m looking for flows around the outer gulf. Any ideas where to see those? I would say, if you are planning something even more audacious than the last swim, it's time you cracked open your wallet for that PredictWind tidal data subscription. You could even use the departure planning tool, inputting your target swim speed to get PW's assistance in choosing optimum day and time. That is assuming using route planning tools doesn't contravene the ethos of a solo swim. If it does, you could just use the advanced tidal and current flow data for manual planning. I sailed back from Bostaquet Bay to Tiri (and home to the river) on Wednesday. The whole way, I was like, really?!? Fogg swam this?!? really?!? It is what I would class a significant achievement. |

It is what I would class a significant achievement. we motored back from Gt Barrier to Kawau on Saturday, knowing it was an outgoing tide I timed arrival to North Channel close to low tide - the run there is strong at mid tide. I was quite surprised to find that when we passed Maori Rock at 1500, with low tide at Sandspit and Bon Accord nominally 1540, we actually had the tide giving us a slight boost as we travelled into Kawau Bay. So some interesting currents around there to contend with. |

My last swim was about 10nm and this time I’m looking for ~15nm.

I think it wasnt up until the 1970s that the bouyage/marker system was upgraded to the rest of nz.At the previous system coincided with the tides which run in reverse to what you would think.1970s was when kawau area was returned so bouyage system ran clock wise. Bit like tamiki straight if unfamilar would seem wrong but its all based on the clockwise system,depends on which angel it is approached |

The entrances to Kawau Bay via North Channel and Rosario Channel respectively are both marked in accordance with the in bound convention. The incoming tide to Kawau Bay flows in thru both these channels (note tidal arrows) and vice versa, altho it would appear per my observation the flow starts reversing before low (and probably high) tide is reached.   |

View AttachmentView AttachmentDo recall there was a marker issue pre 70s.What is port now was starboard back then,it was all based on tidal flows as they do not follow the actuall direction we think.Might be more round the eastern side where the tide flowed in past the behive etc.Do recall the old man explaining it to me ,how many vessels had come unstuck to reverse markings. I see what you mean,same issue rounding north head tide changes up 2hrs before it should. Last weekend were 3.2m? Intersting how tides operate,10.30am high Sunday yet at 9.00am we encountered reverse current in the firth midway across,wind against tide effect when tide flow should of been with wind,caught me out a bit as was expecting a comfortable ride back across before tide change. |
