The Dangerous Archipelago
It is time for us to leave for the Tuamotos, the “Dangerous Archipelago” of such fearsome reputation that, before GPS, many yachts would take the long detour North to avoid them entirely. I can think of few places that better illustrate the extent to which modern technology has reduced the degree of seamanship required to undertake a voyage of this kind. ( Right up to the moment that the technology stops working that is! )
30 years ago, arriving from a position derived from sextant and dead reckoning, running, without radar, towards huge reefs awash and nothing taller than a palm tree ahead, night watch searching the horizon for the telltale white flash of a breaking reef in the moonlight, straining their ears to catch a warning roar of surf, this was not an experience for the fainthearted.
Even for a yacht as blessed with electronics as La Novia, this is still not a trip to be undertaken casually and I am more nervous about this passage than any we have undertaken since leaving England. The bottom line is that you need a navigation plan that allows you a chance to confirm your position independently of the GPS as you approach the danger zone, in a position where you can still turn around in safety if things are going wrong. This is a very long way from help if you park your boat on one of the myriad reefs waiting for you. We decide to use an approach waypoint on the ocean side of the Island of Tairo, which is one of the few spots in the Tuamotos high enough to be visible on radar.
550 miles from Nuku Hiva, an hour before dawn our radar picked up the Island 15 miles ahead of us at exactly the range and bearing that both our satellite navigation and our dead reckoning expected. As dawn broke we could see it on the horizon 8 miles ahead. I confess to experiencing some degree of relief at this unstressed landfall, electronics or not.
Once we have found the pass into Kauehi’s lagoon, the technology ceases to be of much use. Even though we are close to slack water, a 4 knot current is running out of the pass and the sea in its entrance is a maelstrom as the current meets the onshore breeze. Fortunately, there is only one obstacle to miss inside the pass and plenty of room around it, so we can attack the pass at full speed and clear the zone of breaking waves and sucking whirlpools to enter calm of the lagoon. Once inside, constant vigilance is required while navigating in the 8 mile diameter lagoon. It is largely deep and safe but uncharted ‘Bombs’ are scattered around - coral pillars that rise to just under the surface from up to 100 ‘ of water.
If I was to be completely honest, I might admit that we may have very slightly underestimated the extent to which these Bombs are uncharted. On the other hand, we did not underestimate this for very long! It would be no exageration to say that all complacency evaporated in a flash as the first coral pillar, perfectly cylindrical and about 30 feet across, materialised 20 feet to starboard of us at 6 knots and we experienced a “where the hell did that come from?” moment!.
Catherine takes up residence on the bow for all movements in the lagoon.
