After a fairly tough 700 mile passage to Suwarrow we arrived in through the pass and round behind anchorage island and were at anchor in choppy seas and 20 - 25 knot winds. The wind was from the South so the anchorage which was protected from the prevailing easterlies was very choppy! There were two other boats there, and in fact it turned out that we were only the twelvth boat that had visited this year!
 
The main island, "anchorage island" was lush and tropical with swaying coconut palms, some tropical mahogany trees and white sand beach surrounded by turquise waters and sharks, including some more since we arrived! 
 
The island (actually a large number of islands, as it is another coral atoll, with many motus forming the fringing reef) is inhabited only by two park
rangers. We got on splendidly with them and invited them over for Sunday dinner. However they made it clear that Sunday was very much a day of rest for them and that it was partly religious, partly cultural and partly practical that they had Sunday off. This tradition was from the Cook Islands Presbyterian christian practices. This we explained is very much like the Hebrides where we came from and we understood completely.
 
James and Appi, the rangers, are Cook Islanders of Moauri ethnic origin and are first class people. Having invited them over for Sunday dinner, they gladly accepted and we asked Niall to say a grace before dinner in Gaelic, which he did, and which did us all proud. I'm sure James and Appi very much appreciated it too.
 
Our Sunday however had not been spent at rest. Dear God I can assure you this was work of neccessity. We spent most of the day trying to refit the main clevis pin holding our forestay in place. The loads involved in this are enormous due to the sheer size of everything not to mention the quite surprising amount of prebend in our mast achieved by backstay and swept spreaders and shrouds tension.
 
Our challenge was to get the froestay pulled down enough to get the clevis pin holding it in place driven back in. It had withdrawn all the way forward and was still through the forward part of the stainless steel fork and it was only just in the stemhead fixing plate. A few mm further out and we would have had catastrophic damage...
 
An additional problem was that it was not possible to get a clear "run" at the pin with a hammer to significantly apply any force to drive it back in if we could get it alligned.
So we started by, with our (too small scale) shifters to release the two back stay tensioners. We could not loosen them all the way as there was no way at all we would get them back in. So we had to carefully loosen them so that there was still just enough thread grip to hold the remaining considerable tension load.
 
We then rigged a "tournoquet" from dymeema to the top of the fork and the fixing plate for the inner forestay to tilt the fork back and therefor to lower the inner part of it. We then rigged two shackles on the top of the bottom fork fitting (regular squints at the attached photo may help you follow this - if not just get on with something else and i will write to morrow about our hunting and fishing trip we are just going on to the motus) and then rigged some dyneema from each shackle down round two of the anchor rollers and back in a bridle to the windlass to get some downward pull on the stay. This applied huge huge force to the bottom of the stay but each additional method lof applying force was just moving it a mm at a time. Still it wasn't enough. We risked a few more turns off he back stay tension - holding our breath it would not strip through the threads. We the took the jib sheet to the centre of the inner forestay and winched a great big bend in in to drag the mast head further forward and the fixing fork another mm down. We then took two spinnaker halyards forwards to the spinnaker downhaul fixing and winched them tight, tight t-i-g-h-t!  Bear in mind at anchor, the windage on the very considerable bulk of the furled genoa was constantly "fighting" against our attempts to drag the fixing fork down. 
 
One more turn on everything was enough to get the holes sufficiently lined up to let me with a 4" swing on my claw hammer (if anybody out there would like to buy me a Christmas present then a 4lb mash hammer and a 12" long, 1" diameter stainless steel driver would be much more appreciated than socks and hankies) was able to just tap it through. The victorious scream of joy I let out when I got it all the way home pierced the otherwise tranquil Sunday being enjoyed by the rangers ashore! 
 
Friends from "Heavenly" that we had not seen since the Marquesas pulled into the anchorage in the morning and we had them over for drinks after dinner with James and Appi in the evening. Having conquered the forestay fixing I was in particularly good spirits and we had a good evening followed by a great sleep, in order to gather my strength to beat the s**t out of those that I had been telling about this rigging problem but were not listening!
