Wharram Hui Audierne - day 2

On Sunday all the boats left the harbour for a social sail in a brisk wind, with many of the boats reaching speeds over 10 knots. All people without boats were able to crew aboard their chosen boat.

After some exciting hours sailing, all the boats rafted up for everyone to eat lunch and gather in conversation across the many decks. A memorable day, with many happy memories and some great photos.

Spirit of Gaia has arrived in Douarnenez.  Tempes Fetes is starting tomorrow.  Many boats are arriving today.

Wharram Hui Audierne (Brittany) - day one.

The Hui brought many Wharram builders, sailors and enthusiasts to Audierne this year. The presence of Spirit of Gaia drew many people from far away, with people driving long distances from the South of France, Denmark, Germany, Belgium and the Netherlands. For Hanneke it was great to catch up with friends she had not seen in many years.

At the end of Saturday around 40 people gathered on Spirit of Gaia to be briefed about the sailing plan for Sunday when 8 Wharrams will head out to sea for a social sail followed by a raft up off the beach.

Meantime Audierne hosted a 'Rendez-vous de la Mer' and a market on the quayside, with the town's langouste 'Cap Sizun', shoreside booths and the Wharram catamarans as attractions.

The 7 boats attending are Pahi 63 Spirit of Gaia, Tiki 46 'Grand Pha', Tiki 38 'Wax Spirit', Tiki 28 'Louloute', a Tiki 33 (extended from 30), Pahi 31 'Nomadic' and a Hitia 17. Another four boats had registered, but sadly were not able to make it.

More photos of the other boats will follow tomorrow.

Spirit of Gaia has crossed Biscay and is back in her home port in Cornwall after 34 years.

On May 18th we got a weather window of southerly wind for around 3-4 days and we had to take it. The wind did indeed blow from the south, but turned out a lot stronger than we had hoped for and soon after clearing the shelter of the land sails started to come down.

Mizzen down first, little reduction in speed; taking two reefs in the main were immediately followed by lowering the whole sail and still we were sailing at 7-9, 10 knots in rough seas. Later the staysail got a reef and our speed still stayed the same. For the night we lowered the staysail as wind still looked like increasing and hoisted a brand new storm staysail (about half the area of the normal staysail), which I got made after our heavy wind voyage up the Red Sea. For the next two days we sailed under just this little sail at around 6-7 knots while the decks got battered by the sea, from below and from above. But Gaia valiantly sailed on, shaking off water and riding those seas with ease. She had seen worse.

Ernald, our repaired self-steering crew member, was stronger than ever and kept Gaia on a straight course throughout. I counted ourselves very lucky that he had self destructed when he did, or he would have broken on this voyage and we would have had to hand steer the whole way.

The wind reduced during the last night and in the morning we encountered fog on our approach up the Channel. Thank goodness for AIS, which showed us all close shipping. We were then welcomed by the UK Border Force soon after we passed the Lizard.

On Thursday afternoon we sailed into Carrick Roads (Falmouth) in very low visibility, but soon after the anchor was down the sun came out and we were warm for the first time in 3 weeks of sailing.

On Friday we motored up Restronguet Creek to Gaia's launch site at Devoran Quay. We just made it to the Quay on the last tide with sufficient water. She lies there now beneaped waiting for the next Springs this coming weekend.

Everyone is welcome to visit and view the boat. On Saturday 30th May in the afternoon there will be an open day while the tide is in and I will be there to tell Spirit of Gaia's stories of her past voyages and adventures. Maybe see you there?

Our time in A Coruña gave me time to rebuild Ernald, our selfsteering, stronger and better. The old bracket had been strong, but the wood and epoxy glue had weathered over many years exposure. There was enough iroko on board to make a proper and lasting repair.

Due to the delay two crew had to return home, but I was very lucky that two helpers at the Floating Stories Lab in Brittany were eager to take their place and were able to come to Coruña within a day. Since then we have made two sails up the coast and are now in beautiful Cedeira. It looks like we will depart for Cornwall tomorrow morning.

Spirit of Gaia has arrived in A Coruna. We had a good sail from Peniche to Camarinas (Galicia), but just got caught in a thundery rain squall on the last stretch into the ria. We dropped the main fast as the boat speeded up to 12 knots, but sadly the hinging bracket of 'Ernald' our self steering, self destructed.

'Ernald' has been named after Ernald Pearson, a friend since 1972, who sailed many Wharram catamarans, and led the team to launch Spirit of Gaia. He sailed on her maiden voyage from Cornwall to North Spain in 1992, and in 1997 from Sri Lanka to Oman. Ernald died while James and I were sailing the Lapita Voyage in 2009. 'Ernald ' has been an excellent crew member on this voyage, doesn't get tired, needs no food and keeps us on course silently. I hope I can give him some emergency treatment, so he can steer us up to Cornwall, where I will build him a new bracket.

On our arrival in Coruna we were met by Mark of 'Wildling Sailing' on his Pahi 42 Mahi.

We will have to await a favourable weather window here, which may be some time. Lots of Northerlies in the coming week.
