Best way. Manly to the boat works

[44'cruisingcat]

There's a power cable in Port Hacking with an indicated clearance of 12m. Boats with 19 - 20 metre mast heights regularly pass under it.

Golden Dream is a 50' sloop with an air draft of 21 metres.
Reading the advice and seeing the photos encouraged me to give it a try. We followed the course descibed towards the western pylon, and had an estimated 10 metres clearance under the wires (at a low tide of 0.4m).
Thanks for the guidance.

Hi Chris,

Didn't know you were up this way. We're in Aquatic Paradise on a friends dock for some while, doing chores and maintenance on boat and bods. If we can be of help, give us a shout.

Jim

PS Glad you made it without sparks!

You could also go via the eastern side of Russell Island so you do not have to go under the power line at all.

Canaipa passage? There are power lines crossing it too.

When in doubt, fageddabout it.

Same one, actually, and with the same official height. I'm not sure you can get the same extra clearance as you can near the W tower on the main channel.

Hard to say, you do pass quite close to the pylon, but whether the pylon is the same height or lower or maybe higher, who knows...

Dave. Main Channel is exactly as Paulinoz decribed. Hug the western pylon and there is plenty of water and a lot more air. Caniapa Passage its the opposite, hug straddie (stay east) and there is plenty of water and air. To Give you a guide, I have taken Attitude (16.2 m Schionning gForce) ightwave 45s, Outremer 51s and lots and lots of other boats, down caniapa passage . My assessment (unmeasured) is that you will get more air clearance on the caniapa passage than the main channel. The eastern pylon on Caniapa is on straddie up a slope so the eastern side has a lot more clearance.

At 20m air draft, it looked bl**dy close to me the times I've gone under it.

Definitely more water and air to the west

Thanks all, decided to go under yesterday. I found it exactly like Paulinoz's map. The tide was pretty close to the picture too, with the footing of the tower exposed. I went under with acres to spare.


P.s. I measured my boat and it's only 21.5m

got it, can see power lines, thank you mr Paulin.

Got confused as it was mentioned that Canaipa Passage is worse option. Google says this is Canaipa passage. Is this right ?

[PaulinOz]

Canaipa Passage is to the East of Russell Is, between it and North Stradbroke Island.

I take the Western Chanel past Russel island going South, I aim at the Western Pylon in the water and when 3 to 4 meters away turn 90 degrees to Port as I go under. Photo from my vessel of sister ship as she goes under the lines. This shot is of vessel headed North. We have already gone under in front.



I will not tell you what is safe and what is not, this is just what I do.

Thanks for the great information. This enabled me to confidently pass under the power lines, my height is 21m and i had plenty of clearance on western side of channel at rocky point. I also went under power lines at canaipa passage following another yacht with 20m mast they easily had 15m clearance. Thanks again for all the great information. Dean
