KI Crossing to Antechamber Bay — 14-15 December 2024
WOW what a weekend paddle to Antechamber Bay on Kangaroo Island we had. It gave us a bit of everything sea kayaking has to offer.
Preparations
The weather forecast looked very good for the crossing. Saturday was going to be a bit of a bash into the wind and waves but quite achievable and Sunday was just perfect. The group assembled at 7.30am on Saturday morning to beautiful blue skies and very calm conditions in close to Cape Jervis. Further out the whitecaps were building. The pre-launch briefing mentioned several topics such as a check that the group was carrying all of the mandated equipment to go this far from the shore, on water group “rules”, etc. But the main message was to expect the conditions in the middle to be wet and wild. Prepare for waves to wash over the deck!
The leg to KI
And so it was…and for a short time conditions were above the forecast 12Knts, probably up to 15 with even some 18Knt gusts. These conditions challenged some of the group and progress was at times quite slow with Ryan suitably tested as leader in keeping the group together. As Backstairs Passage is a commercial shipping lane, kayakers need to stay in a tight grouping and less than 50m apart. This also applied to the mandated equipment the group required for such a paddle. We were in “unprotected waters” where for every 5 paddlers an EPIRB, flares, VHF and other equipment was required and the group must be within 50m of each other and such equipment.
I was particularly interested in the effect of the tide on our course. The weekend was selected as it was a spring tide with plenty of water on the move. I expected to get some assistance from the easterly ebb tide. The GPS track does show evidence of easterly drift on each stop we had but it really did not feel we were being assisted. I think it would have been a much greater slog into the wind if the tide was not giving considerable assistance. The two balanced each other out.
Chapman River Campground
On arriving at the landing site, the mouth of the Chapman River, little surf was encountered and a hassle free landing was made. The crossing took just under four hours. A portage over the sand bar to re-launch into the river made for an easy paddle up to the campsite. In there the group busied themselves setting up tents and scoffing down some lunch. I spent the afternoon resting and chatting about the events of the day and just how good it was to have such amazing places to camp and explore. Others explored by foot as the area is spectacular.
Back to Cape Jervis
Next morning provided a beautiful sunrise and the promise of perfect paddling conditions. We weren’t disappointed! The plan was to launch at 930am to travel along the north coast making for Cuttlefish Bay. From here I wanted to try a navigation technique called “splitting the tide” where we would paddle for half the crossing in the ebb tide and the other in the flood tide. The net result would be a straight path to Cape Jervis. I was first introduced to this idea by the Tasmanians as a good way to cross the notorious Banks Strait- the last challenge in getting to Tassie when doing Bass Strait from Victoria .
We definitely felt the tide pushing us to the east in the first part of the crossing and had a significant boost in the latter parts when heading to Cape Jervis. Close to Lands End we were achieving 12km/hr with little effort!
On the way across we split into two smaller groups. This decision was based on the fact that we had a diversity of sea kayaks in the group. Some very quick and others just quick. I believe all paddlers would have been working their bodies just as hard. It was just a fact that some of the kayaks travelled at a higher speed due to design. At the other side there was only about a 30minute difference in the time to complete the crossing.
Carb Replacement Therapy
It was a quick pack up with most of the group wanting to head for the bakery and some yummy lunch and carb replacement therapy! The Cape Jervis ramp was the busiest I have ever experienced. Lots of water craft getting out there to escape the heat. On the water it was pleasant but when getting out of the car at Yankallila it was like stepping into a blast furnace. This summer is forecast to be a hot one so sea kayaking might just be the best place to be except for being in front of the air conditioner. Sea kayaking will however be better for the body and have less of an impact on global warming!
