Hi all, another light wind day today... so no sailing. The good thing about this is that is a pressure free way to continue preparing for the upcoming assault on the summit. Malcolm and Richy are now in  the country so we should be in fine form team-wise.

We still need to implement the solutions to the problem in regard to the pitch-instability that resulted in the last flip. I can't wait to talk to the boys face to face so we can flesh this out.

Meanwhile, I think it's about time to ease of this dieting thing. It gets oddly addictive. I'm down to 75 kilos now! That's enough methinks!

Good winds are forecast for Tuesday.

Cheers, Paul.

Hi everyone, well I'm delighted to say that VESTAS SAILROCKET is all but back together. We hope to be ready to sail tomorrow(sunday).

As you could imagine, somersaulting a lightweight 30', solid wing-sailed  craft into the air at over 50 knots and landing wing first fully inverted.... leads to a pretty extensive job-list!!!
The team here have done a brilliant job to get everything back ship-shape. Standing here now with newly skinned wing sitting behind me... I'm actually pretty amazed at what we have accomplished.It was not only the repairs, but all the media obligations, e-mails from friends and supporters, record ratification process and day to day organisation that had to be done as well. A few times I found myself laminating carbon on one end of the table whilst replying to e-mails and uploading videos/pics on the other end! It was pretty mad.
So, now the record and subsequent flip is behind us and we are looking forward. There is one very big bottle of MUMM Champagne that remains. It sits in a wooden box under this table as I type. Every other bottle has been popped.

Malcolm and the design team are working hard on understanding what initiated the flip. Obviously once it was initiated the 50+ knot apparent wind force got under the beam and off she went... but why this time and not others? We feel we are coming closer to a full understanding. The foil has been inclined a further 2 degrees to give a larger down component. the wing will remain at the last setting. Chris and the boys at AEROTROPE are right onto looking at the dynamic model of the boat... the 'moving picture' of all the forces and accelerations brought on by gusts and turns. It is clear from the video that the boat did a slight weave before lift off and the effect of this needs to be fully considered. Chris, as usual has already come up with some pretty insightful stuff. Fortunately we have access to some pretty sharp minds who are all chipping in with all their skill and knowledge. As we work through the night here in Namibia doing all the actual physical work, it's great to know that they are dealing with the science.

If we can keep that nose down and maintain the control we have had throughout the last few runs, we have no doubt we can achieve runs over 50 knots. It is an 'if' but the more we look into it the more the issue becomes understood and the outcome predictable. I was pretty impressed in the end with how VESTAS SAILROCKET performed. It was exactly how Malcolm predicted. I was getting ready to sail in stronger winds to achieve runs over 50 but he always maintained that it would be down to flat water and winds of a little over 22 knots. Spot on.

I have watched the video many, many times now. (I wish I had the onboard camera... but thanks to the total incompetence of those who supplied the original dud... we missed out and still don't have one! What is wrong with you people? We throw money at you and only junk comes back! To miss that somersault onboard was criminal). It was pretty spectacular and I am grateful for getting out un-injured. I don't think it will affect the way I sail the boat in the future other than to be a little more respectful of the power at hand. There won't be any 'Maverick flashback' moments only a little more caution based on experience.
During the next runs I want to have a calm moment in the cockpit at over 50 knots. A moment where I just enjoy the 'here-and-now' of sitting in this wonderful boat as it does it's stuff. It's the moment that you work towards for all those years and I don't want to miss it. It will only be a passing split second... and I will need to be calm and in control to realise it... but I want that moment. it will remain forever.

Unfortunately George Dadd had to leave us as he had already pushed back a number of prior comittments to stay for the record. George was a huge assett and put everything into his work. He was fundamental in helping design and build the new control package that was the real breakthrough for us. I pushed him hard and was constantly on his case... I'm so glad that he saw the reason and results of that pressure. It was a brilliant few months for George who will go back to his Marine Engineering course at Southampton University with an absolutely priceless experience firmly under his belt. Thanks for everything George.
Replacing George will be Richy Pemeberton. Richy has been with us from the start and actually designed the foils we are sailing with. He's a Doctor of Hydrodynamics which I hope means he is pretty handy with sand-paper! Richy should be arriving with Malcolm tomorrow (sunday) evening. Malcolm is hopefully coming down to witness the culmination of a lifes work.

We have 6 days left to have a shot at this record. The weather has been pretty crazy recently and we haven't actually missed much. All we ask is another day like the last one please.

To all of you who have, emailed, commented on 'you-tube', phoned, skyped or just dropped in to support and encourage us. Thankyou very much. IT ALL GETS READ AND SPREAD. We will do all we can to do it justice.

We are still waiting for the nitty-gritty details of ratification but there shouldn't be any issues. We must continue to raise the hurdle as I'm sure both Hydroptere and the Macquarrie Innovation boys are keen to knock the 'Rocket' off its perch.They are both capable so we must push on.
We hope to be ready to sail tomorrow. We would like to do a shake-down run first before going all out.

Cheers, Paul and the team.

Hi all, sorry for the wait but it wasn't for lack of trying on our part.

http://www.youtube.com/watch?v=EfJK5ycx_hg

An even higher res version will be available for download off this site later today.

On the first run I had the wing sheeted in to 15-18 degrees. On the second fateful run I focused on bringing it in to the optimal 10 degrees. The wind had built by a knot or so and although the mean average was around 23 knots... that means gusts to 25. We have taken the B+G wind sensors off the back for record runs so I can only guess that a gust like this and having the wing in hard is what caused VESTAS SAILROCKET to accelerate so hard to the point of overloading. Perhaps I should have been more cautios but after the stability and control of the first run and previous runs in even stronger conditions I simply thought that this was not the time to hold back. It is an 'outright world speed sailing record' attempt after all. In the end it was no doubt a combination of effects brought on by the newfound speed and high apparent wind speeds that come with it. VESTAS SAILROCKET would have turned that 23 knot breeze into a 50+ knot apparent wind gail coming from around 26 degrees off the bow.

As you could imagine, we did do some substantial damage to the wing. You don't get away with a crash like that lightly. Thanks to the brilliant design by AEROTROPE... it has survived and it is fixable by us here in Walvis Bay. We are already well into it and hope to be back on the water  for more runs in the near future.

More important is the issue of understanding and preventing this from happening again.

Malcolm is working hard on this with input from all the team. We want to dampen the whole boat down a little and approach these speeds again from a point of safety. We will angle the foil a few degrees more so it is pulling the front planing surface down harder and stand the rig up so it is pulling up less. We had already begun moving in this direction and you can see that the leeward pod isn't flying quite as high as it had in some of the previous runs. We think that the main foil may be flexing a little more than we anticipated and that we should speculatively account for this with safety in mind. We will also look at adding 'lift-spoiling' devices on the inboard end of the beam. From my perspective I will be a little more cautious of how aggressively I sheet in. The main flap wasn't even pulled in on the flying run. When it is it helps keep the nose down.

The team is doing a brilliant job here and yesterday we really began to make solid progress towards getting back on the water. It is just beginning to dawn on us what we have achieved and the potential of where we are going. To make such huge gains at this end of the speed range is staggering.

We have had so many people calling, e-mailing and simply dropping in to give their support and encouragement. I want to let you all know that we appreciate it and every e-mail and comment posted here gets read out, saved and shared.

It was really nice to get one from the Hydroptere team. It is great to have such a hot boat to compete with. We both desperately want to be number one but I think we both appreciate the other teams efforts and presence. In the end we sent them all our GPS data to see if they got the same numbers as we did using their programs. They did. Although we are ahead of them now... I by no means think we will be for long as I'm sure they are going to hungry to get their 'fastest boat' title back.

On another note, On the record run... after 40-50,000 odd sea miles... my little koala mascot flew out of my rash vest and is gone. I figured he either said enough was enough... or figured I didn't need him any more... On the next run we flipped the boat!!! Good luck out there Kev, I hope you enjoyed all the sailing as much as I did. You checked out in style.

Cheers, Paul.

p.s. the helmet stays. There is a real helmet inside by the way. The fairing will be heavily drilled and cut so as to snap off with minimal force. My neck is a bit sore and yes I was very lucky.

Hi all, thanks for your patience. the video of the run is coming. It has been edited and is uploading in the background... for the third time. Internet connections deteriorate here with the weather for some reason! The wind is honking right now. Too much for us.

I have assessed the damage to the boat and it is fixable. I have lost a day trying to manage all the media demands and am typing this in a white dust suit in between repairs. We are only a small team remember. I want to be back in the water in a week.

As soon as 'youtube' accepts the video I will send the link. I will also endeavour to upload a higher res version for downloading off this website.

The Trimble data is being worked through now. the speed looks as we predicted at 47.35-4 knots. The peak has gone up a bit to 52.22 knots on the first record run.

Stay tuned.

Hi all, well yesterday was truly epic.

The day shaped up better than forecast and I went over feeling strangely calm. Conditions on the course looked perfect, the sort of otherwise ordinary day that I always envisaged.

What was to follow was anything but ordinary. The seemingly innocent boat we pushed across the Lagoon was about to live up to its 'Rocket' title. It was a spark to a powder keg.

We stopped off at the timing hut to wait for the wind to build and swing. I tried to have a little snooze under the table. Surely enough, good ol' Walvis turned it on and away up the course we went.

I was determined to bag a record. I knew our wonderful boat had it in her to do something special and that at the top of the course... it was up to me to make sure she was allowed to do it. I had had enough practice... and this was no longer practice. This was a proper world record attempt. This was the dream. It was time to dig a little deeper, judge yourself as critically as you judge others. "what would you do in this situation". From the outside things are simple, from the inside... far more complicated. Sometimes you need to be inside with an outside perspective. I suppose having only one option is a calming thing.

The setup procedure was careful. I told the boys to take care as something we have all worked for was waiting down the other end of the course. Everyone left Venassius and me at the top of the course as they hurried back in the support RIB to take up their expectant positions. Things looked perfect. The boat was perfect. It was time.

There was enough wind to sail a 'flattish' trajectory onto the course. I built enough apparent to attach flow onto the wingsail with only a slight dip. we were off. I was quick to sheet in and get on the main flap whilst simultaneously switching from foot to hand steering. A real one man band affair. VESTAS SAILROCKET was going hard and I had tunnel vision. we had made an adjustment to the rig to stand it up a couple of degrees so as to hold the nose down and it seemed to make the boat ride flatter. Control was excellent. At one stage a gust pulled the nose away and I brought it gently back up. The main flap was in but I noticed that the wing angle was still a little eased. It was too late to change. The boat was smoking... but balanced. I held onto it until I was certain that a solid 500 meter average was recorded... and then dumped the flap and eased the wing. No more big bear aways to slow down. I pulled on the leading edge bridle to slow her down by feathering the wing and it worked a treat. Hiskia caught the boat on the shore. I was pretty surprised by the data on the GPS. It read a top speed of 48.90 knots and an average of 47.35! I told the team over the VHF that they were now looking at the fastest boat in the world and congratulated Malcolm on designing it.

VESTAS SAILROCKET OVER 50 KNOTS IN PERFECT CONTROL.

There was no supernova of emotion, no tears... just huge smiles and a sense of arrival.

We did some pieces to camera and then carefully dropped the rig. Then we felt safe. It was only later when we checked the two onboard GPS systems that we saw we had actually hit sustained speeds over 50 knots peaking at 51.76 knots. We averaged 46.4 knots over 1000 meters. The mean wind speed was around 22 knots. VESTAS SAILROCKET had definitely arrived.

I reflected on the wing angle during the run and the knowledge that I could come in closer.... to flatter water. armed with this we headed straight back up the course. the wind was up a knot or so and the course was still lovely and flat. This was our dream day. We had plenty of time.

The wind was gusting to 25 on the second start indicating an average of around 22-23 knots... no more. I did an even flatter start up procedure focusing on getting the wing into 10 degrees as soon as she accelerated... and bloody hell... did she accelerate. apparently she pulled 0.35 G's all the way up to 52 knots before the nose lifted. I expected her to step sideways as before but not this time. The nose floated higher... and then it went quiet... I was flying. i waited for some sort of touchdown... somewhere... but it didn't come. the nose just kept going up until I was lookin vertically up at it! There was no rolling and I was just a passenger. It was still quiet... and strangely dry as we continued the loop. I sort of knew I was inverted. It all seemed to take so long. I consciously thought "righto boy, when this thing smacks down... get the hell out of it because you're gonna be upside down"!!! I smacked down hard. Like someone big had full palm slapped my helmet with all their might. I was out of that boat in an instant. I was a bit beat up and bruised... but alright. I lay on the upturned hull and got my head together. My helmet was broken but I dragged the mic. over to let everyone know I was OK.

Damnit!

We had been in similar, although less spectacular predicaments before. I assessed the damage and warned the support RIB crew not to make it any worse as sometimes it isn't as bad as it seems. The platform looked oddly intact... but the wing had had a hard time.

Slowly we dragged the sorry pieces back to the shore where a heap of local wind and kite surfers helped us to sort it out. we left the wing on the shore where it still sits as I type this... and brought the boat back. We were all pretty happy when we removed the TRIMBLE GPS and saw it happily blinking away despite complete immersion for some time. This meant our data was safe from the previous record run. I was worried we might have lost it.

LtoR VENASSIUS, HISKIA SINDIMBA, PAUL, HELENA DARVELID, BRAD WITHEMAN, GEORGE DADD.

So we had learnt something new. We had discussed the possibilty of this happening but had perhaps not expected to go this quick this soon. Today the potential of this boat just took over. We didn't need to force it. The Rocket simply did what it said on the box.

I felt a mix of emotions. We were the fastest boat on the planet and had broken a couple of world records... but we had narrowly missed out on our ultimate goal of becoming undisputed number one. We also had the ability to smash the nautical mile record and significantly raise our best average... however, overall I felt good. My head hurt and my right elbow was seizing up... but I felt good. The cause of the loop could be rectified by simple tuning of the geometry. We had beaten many of those that we admired for many years and had overcome a mountain of hardship in doing so. This was but another obstacle to be overcome, nothing more nothing less. I am now safe in the knowledge that no-one can dispute that this is a very viable concept of enormous potential. in fact, I think it is perhaps one of the most significant speed sailing craft of all time. The concept behind this craft is future proof. This Mk1 prototype has also shown itself to be a pretty damned good first stab too.

So we got the big bottle of MUMM out of the WALVIS BAY YACHT CLUB and shook the s**t out of it!!! We even drank some. Next we went through the data. It was then that the real performance came out. I won't go into it too much until we get the TRIMBLE  data anylised... but this boat is rapid.

We all went out for dinner. I finally saw the above pics and associated Hi-def video. It sure was epic. What do you do with pics like this? Bugger it... we will put them out. This stuff comes with the turf. We ARE pushing the limits here on prototype craft. Make your own call. I reckon we can fix it and I reckon we can break the outright record. We built the boat and we've fixed her many times to get to where we are.

This is more than a rollercoaster... it's got all the rides of the fair thrown in.

Stay tuned.

The wind is kicking in and already gusting to 22 knots. the tide is nearly in and all the team is here. We will be on the water in half an hour.

Cheers, Paul.

Wed, 3 Dec 08 12:49

... but we will see what happens. We are once again very keen to get on the water. yesterday the weather played a cruel trick on us. At 5p.m. the forecast winds hadn't arrived and it was all looking flat. It's pretty unusual for wind to pick up at this stage so we called an end to the day. Later as Helena and I were winding things up the wind began to build. seeing the chance to go for a windsurf we rigged up and went out to Speed-spot.

Conditions continued to build until I hate to say it... my otherwise ideal windsurfing session was destroyed by the knowledge that we should have been out there with the boat!!! It made me slightly sick after the teasing mother nature gave us the previous day.

After over a year on site we are pretty good at guessing local conditions and keeping our options open. We don't miss much anymore... but yesterday we did. I don't think it would have been an epic day... but it would have been valuable none-the-less.

So the forecast for today has been 'yo-yoing' with every review. It is currently forecasting winds to 24 knots which is pretty ideal. So we are in full 'go' mode. The tide will only allow us onto the course at around 4p.m. local (1400 GMT). The 'live-feed' will be coming out of the timing hut once more and we remain as hungry as ever to start collecting records.

The new 3mm rigging line arrived from MARLOW yesterday and we spent the morning at BENGUELLA ENTERPRISES doing stretch and break tests on their test bench to find out how best to use it for our own purposes. The rigging will represent about a 1.5kg weight reduction and about a 45% reduction in windage on all standing rigging. The actual tests were invaluable in showcasing some real do's and don'ts with how to splice and lash the ends for our specific purposes. Thanks to Barry and the boys for helping us out.

Righto, better keep putting it all on then.

 

Cheers, Paul

Cheers, Paul.

Still no wind today, we are on standby. At the moment there is only a 8-10kn Westerly breeze blowing. Will keep you all updated if we go out. Helena.

Tue, 2 Dec 08 07:49

Well we did all we could yesterday to go for a sail ... but we were denied our big run.

We got onto the course as soon as the tide allowed us. The wind was still building and still too far west which meant we had a small swell running parallel to the beach. Even when the wind was bang on in our range... it was too far west. This usually means it is still building and it will only peak when it has swung well into the SSW. This turned out to be the case. With winds up to 31 knots we chose to sit and wait in the timing huts taking turns to hold the boat.

We often commented on one of the best decisions we ever made in this project... changing from wetsuits to MUSTO drysuits. The level of comfort goes up tenfold. Now when people come out to help... there is a chance they will come back again:) The wind and the cold just don't get through and even after a few hours of standing in the water in howling wind I laughed watching the guys playing around like kids blowing up their suits and having drifting races and sumo wrestles. The 'waiting game' is no fun out here if the cold and wet is soaking through to your bones. Comfort really matters as it allows you to focus soley on the objective.

So the wind blew, the timing hut shook, the snack bag grew light... and everything got sand blasted... and we waited.

The fact is that we couldn't have gone back even if we wanted to. With the tide still flooding into the lagoon against the strong wind, the chop on the crossing would have been punishing. We had to wait until the tide turned at least. The 'live feed' kept us entertained.

The wind began to drop slightly as 31 knot gusts dropped to 30 then 29. The wind had swung into the SSW and the swell disappeared. It was only wind chop now. I began to think we just might get a run in and optimism returned all round. We struggeled to get our 'sixth hand' today for various reasons so we called a good friend in local tour operator Naude Dreyer. He dropped everything and came out to help. Naude predicted the wind would drop due to the large clouds building way in the North. I wasn't so sure as usually once it is in... It's in.

We all began watching the TACKTICK display. I decided when we stopped seeing solid '27's that the gig would be on. As soon as that was the case we jumped and headed to the top of the course. By the time we got there... the wind had softened considerably... and moments later we knew the best had gone. I don't kick myself. It was a very unusual situation and none of us would have guessed it would be that sudden. So we did a run anyway.

It went well and VESTAS SAILROCKET sailed beautifully. In winds averaging around 14-15 knots we managed a 34.88 knot peak and a 32.87 average over 500 meters. One trick I tried at the end was stopping in a straight line by pulling on the forward bridle to force the wing to feather... It worked really well... but conditions were mild to say the least. Still it is worth exploring further.

So the rain clouds are still messing with us. Today is not forecast to be that strong but we will remain on standby nonetheless. I'll try and get some video posted.

Cheers, Paul.
