The Au’au Channel
(commonly referred to as the Maui Channel)
If you are reading the reports of our swims, you are probably contemplating swimming across a stretch of water somewhere. And since most of our swims are long distance, you may also be interested in the extra challenges that this entails. Races are fun, and give you the opportunity to test yourself against others.
But crossings (which you have to organize yourself) add a whole new level of challenges. You have to contact people for information. You have to organize a boat and other support equipment, crew and logistics. You will also have to do some research into the conditions you are likely to encounter, and must prevail against. And you must plan and structure your training accordingly.
These challenges and the pioneering aspects (there are stretches of water all around the world, which very few people have swum across) are what makes doing crossings, for us, so interesting and exciting.
An easy crossing to start with, is the Au’au Channel, between the Hawaiian islands of Maui and Lanai. Easy, because a fair bit is known about swimming this channel, due to the annual Maui Channel Swim. Held in August/September, this race caters mainly for relays, but also has a solo category. Heading from Lanai to Kaanapali beach (in the tourist area of West Maui), the swim is 8.8 statute miles (approx. 14.5 klm).
We chose the Au’au Channel as the second crossing for our visit to Maui. We had both completed crossings a few days prior. Penny swam the notorious Alenuihaha Channel (Big island to Maui – 43 statute miles) in punishing conditions, and I did the shorter, but still challenging Pailolo Channel from Maui to Molokai.
After these swims, we were trying to decide what other water based tourist activities we should try. Kayaking, snorkeling, diving and whale watching were all on offer. But we were both in good shape, and our boat skipper had no other commitments. So we thought “why not do another crossing?”. There were also large numbers of humpback whales in these waters (they come here each year from November to March, to give birth and nurture their young) and we were really hoping to swim with some.
We planned to swim from Kaanapali to Lanai (the opposite direction to the annual race) due to the forecast NE wind. This would give us some assistance as we would swim in a SW direction. Curiously, whilst hundreds of people have swum from Lanai to Maui, only three people (all males) have swum in the direction we were attempting, since the channel was first conquered in 1970. So there was still a pioneering aspect to this swim, and a little uncertainty as to how the currents would affect us.
Our swim day of Thursday, March 19th, 2009 came with a forecast 10-12 knot NE breeze and overcast conditions. It was the day after the neap tide (= not much current). And water temperature was 72F (22C). All perfect for swimming.
We met up with our skipper, Jim Dickson at Mala Wharf (Lahaina) at 8.00am. With him was deckhand, and our feeder, Rob Knake. Jim has piloted many crossings (including our previous swims), but Rob was a first timer, so we briefed him of our requirements on the way to the starting point.
After applying sunscreen and some grease, and taking a final drink, we jumped in at 8.30am for the 200 metre swim into shore. Kaanapali beaches are lined with big hotels and we must have been a strange sight to those strolling along the beach, or enjoying breakfast in the beachside cafes.
We started the swim over fringing coral reef, with a group of people to our left taking a surfing lesson, and others to our right (beyond the small break) about to descend on a guided scuba dive. Swimming was easy at the start, as there was only a slight swell and virtually no breeze. The high rise hotels and Puukukui (west Maui mountain) would provide a wind break for the first couple of klms. And low tide was scheduled for 10.00am so any influence from the current would be minimal for the first part of the crossing.
Like all Hawaiian waters, the Au’au channel is crystal clear. Penny and I swam together (she did a mixture of freestyle, drills, breaststroke and backstroke to stay at my slower pace) and we could easily see each other through the water, from anything up to 50 metres away.
Looking down, apart from the fringing reef hugging each coast, there was nothing but a deep cobalt blue void. There were no fish (except in amongst the coral in the shallows), no sharks (encounters in deeper waters are not common) and unfortunately, no whales to be seen. Although the guys on the boat said later that they were everywhere, and some quite close. At one point, we both recall swimming through a strange patch of upwelling water, which we can only surmise was caused by a whale swimming close by.
Unlike our other two Hawaii channel swims, we did see a lot of jellyfish on this crossing. The resulting stings were very minor, leaving us with only a few itches (although bluebottles inhabit these waters at certain times of the year).
As we passed the half way point of the crossing, the now incoming tide started to push us sideways (from left to right) and added some distance to the crossing. This is evident by our course shown on the chart. But Jim had taken this into account and planned to land us at Halepalaoa Landing, on the southern end of Lanai.
We read an interesting story about Lanai. It must be a beautiful place as Bill Gates (Microsoft) chose to get married there in 1994. The story goes, that to ensure privacy, he booked out every hotel on the island, and kept all rooms empty apart from invited guests. And then he chartered every helicopter on Maui, and paid them to stay on the ground. As we approached the beach and could clearly see the many coconut palms, it occurred to me that we had found a novel way to gate crash such a party.
The reef, as we approached the beach, was very shallow. So we slowed right down to avoid bumps and coral cuts. We completed the crossing together in 4 hours and 31 minutes, covering a straight line course of 9.98 statute miles (16 klms).
The breeze, not that there was much of it at any point in the swim, had died right out, which made for great whale watching on the trip back to Lahaina. Jim and Rob did a fine job in supporting us, and the crossing turned out to be like a very comfortable training swim (suiting us fine, as we had a few sore bits from the previous swims).
For the record, I was the fourth male and Penny, the first woman, to complete the swim from Maui to Lanai.
Hawaii is heaven for open water swimmers, and Maui is the best place to base yourself for a crossing in these waters. Even the small beach where we stayed in South Kihei, boasted clear water, coral, and turtles almost every time we went for a dip. And we thoroughly recommend Maui as a great swimming (and holiday) destination. Just be aware though, that you won’t have everything organized and laid on for you. You will have to organize the crossing to YOUR REQUIREMENTS. This includes discussing with your skipper, before the swim, how you want it run and what you expect of him, and vice versa.
