On passage: Cocos to Chagos
We left Cocos on Monday 4th September, having spent nine wonderful days enjoying the cruising life: snorkelling, sundowners, beach barbies and the odd chore. We were sad to leave, as Cocos had quickly become one of our favourite anchorages.
Cocos is a 'fork in the road' for cruising boats in the Indian Ocean, as it is here that boats must decide whether to sail the northern route (via Chagos and Madagascar) or the southern route (via Rodriduez/Reunion/Mauritius) to South Africa. The distances for either route are roughly the same, however Chagos lies at 5� South, which puts it in the ITCZ (the doldrums), while Mauritius lies firmly in the trade winds. We chose to take the Northern route, mainly because Chagos is famous amongst cruising boats as being home to an almost permanent community of long-term cruisers who have 'colonised' the otherwise no longer inhabited atoll, often returning year after year or even settling for long periods (up to 18 months or more). At this stage we had an outside chance, with a fast passage, of meeting up with our friends Eagle Wing and Petrel, who had already been at Chagos for five weeks. Another advantage for us was that this route would allow us to visit Africa - or at least Madagascar and Mayotte (in the Comoros Islands) - and then sail down the Mozambique Channel. Regardless of the route taken, all the boats leaving Cocos would eventually arrive in either Richards Bay or Durban.
Although the weather had been perfect during our stay in Cocos, it changed as we left the island and the first dramatic squall hit right as we cleared the pass. The start of our passage was therefore uncharacteristically slow: 10 miles in the first three hours which we spent the next weaving in and out of squalls with the wind coming from all quarters and varying from 0 to 25kt. Eventually the weather settled down, but for the first three to four days we were getting at least 5 decent squalls a day which required reefing down but were typically followed by windless "holes". It was some consolation but gave little hope for improvement that our friends Julie and Chris on Cisnecito (Swan 46, sailing a few days ahead) reported similar, variable conditions. In fact, on a seemingly windless day they were caught in one 40 kt squall with the spinnaker up and were knocked down, after which they got a bit "gun-shy" about flying it.
During the first week of passage, the weather forecasts indicated that the ICTZ was moving south a little earlier than usual, or perhaps we were getting the same 2-week cycle of ITCZ activity which is known in the Pacific - either way, we had lots of rain and were constantly reefing and setting sail. Still, we were making reasonable progress with over 150nm logged each day towards our destination.
On day 4, we got our first taste of the light winds which would stay with us for the next 4 days, this slowed us down to less than 100nm a day. Instead of avoiding squalls, we were now chasing them in order to get a bit of wind and some rain to give us relief from the heat. On windless days, we tried to fill the days with diversions to make up for low mileage: scones for breakfast, pizza for lunch, drying flying fish for lures, popcorn and tonic at sundown. Although the boat is fairly comfortable when becalmed, it can get very hot as were within 500nm from the equator. We even tried to cool down by putting our feet in a bucket of water as we were once advised to do in the Med (it works!).
On Tuesday, 8 days after leaving Cocos and having made-good about 70nm in the previous 24 hours we heard on the net that our friends on Freefall had left Chagos and were getting southerly winds of 35kts. Although neither our lull nor their strong winds were shown on the weather the weather-fax, we speculated that a low-pressure system had formed to the SW of Chagos which our friends had sailed into and which was blocking our winds.
Early on day 9, during Henri's morning watch, an enormous squall approached. We quickly reefed down as the white-caps rushed towards us. For the next 40mins or so, we were in a heavy downpour with wind over 25kts from the west. Henri thought the clouds had looked more like a front than a squall, and when it passed over us, we could see it was truly enormous - extending for miles in either direction - so it was likely to be either a line squall associated with a cold front, or a front itself. Sure enough, the next weather-fax showed a low pressure system just to the south of us. Within a few hours we had crossed to the north of it, and finally, the wind filled in giving us good southerly breezes which more or less held until we arrived at Chagos on Saturday 16th September. We had sailed the rhumb-line course, in retrospect, it would have been better to have stayed south and tried to stay out of the ICTZ for longer. As it turned out, other boats had similar experiences and our total time of just under 12d for the 1550nm was quite typical. Our only frustration was that we had not caught Eagle Wing and Petrel, as they understandably set sail to take advantage of the favourable winds - after spending 6 weeks at Chagos. On our arrival, we were delighted to be welcomed by Cisnecito who had arrived a few days ahead of us and ready to introduce us to the Chagos way of life�.
With light winds and at slow speed, we had less fishing success than usual. We caught a blue-fin tuna (which we made into delicious sushi), a skipjack and a dorado. On the way into the pass, we caught a bonito rather than the sought-after wahoo. Nevertheless, even this fish was delicious, marinated in chilli and smoked over a coconut-husk fire at Takamaka Island (Chagos) the next day.
