A pretty good stab at the mile for starters!!!
Thu, 26 Feb 09 18:15

Hi all, just got in and the team are tearing through the data, photos, footage... and snacks.

Looks like we did somewhere around a 41.2 knot average (all subject to WSSRC ratification) over the mile which should be enough to move us up to second in the mile ranking overall and take the course record off Dunkerbeck along with a few other smaller titles (Australian mile, 'B' class mile). Hydroptere is still king in this department  for the time being... but we will be back. We did a 44.02 knot 500 meter run and a peak around 46.

It looks like we jumped perfectly through the days weather window as the wind dropped slightly after the run. We hit the course just after it stopped peaking at 24's and as it shifted to a more ideal direction. The WSSRC commissioner noted no significant tide (it was bang on high tide anyway.

I was happy with the start up which I delayed a little so as not to go too fast whilst still out in the rough. Sailing a nice clean course had all my attention and I focused on carefully aligning VESTAS SAILROCKET's pointy nose at the SEAFLEX buoys. I was also taking note of how light the nose was as the gusts hit. she still felt pretty 'soft' up there. I left the wing out at around 15 degrees but had the flap pulled 80% in. I knew it was pretty fast as she would jerk forward in the gusts. The mile did seem like a loooong time. I was aware that I wasn't saying much. Keeping a good straight course had all my attention. Looking at the data now it seems that the course was very true. I figured that the average would be solid but the run wasn't 'ballistic'. Considering it was our second run with the new foil and setup I'm pretty happy overall with the progression. By the end of the run I wasn't totally confident with the boats behaviour. Whilst the steering was great, the slight pitching was a little concerning. It felt fast... as it always has. But I now know what lies at the end of that dark alley. Malcolm wanted us to do another run after the first around the 45 knot mark just to progressively work up... so this one should be perfect from a data-base perspective.

The trip across the Lagoon is always a messy afair as is getting the boat back at the end.

So I guess I'm pretty happy with todays effort on a number of fronts. It's always nice to nail a difficult weather window and I'm happy with how I sailed the course. The boat in general felt good and the data collected off the TRIMBLE GPS and PI RESEARCH data logger is all spot on. Armed with this we will be able to move forward.

 

MALCOLMS COMMENTS FROM LOOKING AT PI RESEARCH AN TACKTICK DATA...

Had a brief look just now.No major surprises.

  • The steering seems quite close to centre (averaging a round -2 cm) - good
  • The rudder load seems to be a round 70kg average which seems a bit high. Did you check the calibration ?- I am using Georges latest workbook (as sent to you) but there could have been a shift.
  • sheeting mainly in the 14-16 region

The photos are great - it looks slightly light at the front (less spray) in one of them but it  could just be a dynamic thing in the waves etc. Need to see video to get overall impression of loading.

Hope good wind comes soon.

Malcolm.

Cheers, Paul.

Righto... here we go again!
Thu, 26 Feb 09 12:58

Well let's hope that today doesn't 'wierd out' on us like yesterday did! Just like yesterday... all looks good and as forecast.

Once again we will try for the mile and see what happens.

The live feed will be up shortly after we cross the lagoon.

Currently the wind is around 13-15 knots.

Cheers, Paul.

BIG WEDNESDAY shapes up!!!
Wed, 25 Feb 09 09:58

The forecast is predicting winds from 19-25 knots and it has been pretty spot on for the past few days. The tides are perfect and VESTAS SAILROCKET sits patiently waiting outside. Big things can happen on days that start like this.

I feel that it will be my job today to try and rein it all back in a little. I will not go out there with a view to maxxing the boat out on the first run. We have only done one run so far and although it all looks good... we must remain cautious. I'm thinking that maybe we should focus on the nautical mile record as the required average is lower and therefore less risky. We have seen that we can do it on the Walvis Bay course... but only just. Our first attempt saw us stroll through the mile at an easy 36. something knots in mild winds. It would be good to get this under our belt before pushing for the higher speeds and associated risks of the Outright record. No doubt we will be learning and refining along the way. This can all change depending on the way the days weather develops.

Hight tide this afternoon is at near on 4 p.m. It won't be until around 6 p.m. that the tide starts to really fly out  of the lagoon. We need a strong outgoing tide as this makes the water run with the wind and hence makes it flatter out in the channel. The flat water in the channel is necessary because I need to use the entire 1.04 nautical miles of 'speed-spot' at full speed in order to do a good nautical mile average and hence I over-run the beach at the end at high speed and slow-down out in the channel. I don't want to hit a mogul course at 45 knots. I then need to sail for another mile across the lagoon to get to a beach where we can de-rig VESTAS SAILROCKET.

You can see in the above picture that the speed course isn't perfectly straight and this has an effect on the course sailed over a nautical mile if you want to stay in flat water. The closest place to park VESTAS SAILROCKET when I miss the end of the course is on the beach at the left hand side of the pic running vertically up the page. It's a bit of a saga that does nothing for quick turn-around-times. If the wind does hit it's predicted 25 knots then it will probably be around the time of high tide and therefore it will be both too windy and too rough to attempt the mile. We'll see.

BRIGHT SPARKS WANTED

On another note... for those of you who might be looking for work relating to our field... then it just so happens that one of our Team members/sponsors/designers, AEROTROPE, is currently looking for someone with the right skills to join his dynamic company and assist in a wide range of interesting projects... which will no doubt involve plenty of stuff relating to speed sailing and its ongoing development amongst other things. If you are interested then look at the following http://aerotrope.wordpress.com/vacancies/ and go from there. Who knows, the person that reads this now might be on his/her way down to Namibia in the not-so-distant future!

Righto, let's go. All the team is here and the show is on.

Cheers, Paul

World Record Attempt 2... Run 1
Sun, 22 Feb 09 10:46

Walvis bay delivered the goods today with perfect conditions that would have enabled us to push to the limits... but we aren't ready for that just yet.

We will approach that stage with caution. Seeing as we have just fitted the new curved foil we need to make sure that the complex steering/control system is 'dialled in' to it. Remember that at high speed we are trying to operate the rudder within fractions of a degree of movement. To do this, we need to have the rudder aligned practically perfectly with the loaded angle of the main foil. It is after all the main foil which determines the centre line of the boat and not the boat itself. As mentioned in an earlier blog, we use an array of Lasers, jigs and digital equipment to do this. It took two days... but the effort seems to have paid off.

I want to make full-on record attempts ASAP but understand that this will happen sooner if we spend the time now getting all these aspects right.

So we headed across the Lagoon to 'Speed-spot' with a fairly new team with our focus not on top speed, but on checking first settings. I guess it was a shake-down run.

'Speed-spot' was literally teeming with birdlife. Flocks of flamingoes, Pelicans, gulls... and other stuff beyond my limited twitching powers. Here's a few of Helena's pics just to give you an idea of some of the other wonderful benefits of speed sailing in Africa.

Alright, back to business... The wind was building to 20 knots as we hit the top of the course. I didn't want to do a high 40's run straight off in case something was amiss. I decided to only sheet the wing in to around a mild 18-20 degrees instead of the 'full-bore' 10 degrees... and not pull on the main flap. If all went well then I would sheet in a little harder towards the end of the run.

It was great to be back in the cockpit on such a glamorous day. VESTAS SAILROCKET felt just as sweet as I remember. The start up was easy and the speed came quickly.

I spent most of the run monitoring the rudder angle to make sure it was in the 'fine' band giving fractional inputs rather than the 'coarse' band which can easily upset the boat by either sending it into a round-up to windward or unloading the front end in a bear away (it reduces the angle of attack of the inclined foil which also reduces the 'down' component. This factored in the flip scenario). With the wing eased, the boat will tend to want to turn towards the beach more than usual. When everything looked and felt fine I sheeted in to around 14 degrees and noted that the rudder trim approached zero i.e. the middle of the 'fine-trim' band. The time spent in setting the boat up had been vindicated as it shows how well we are coming to understand the whole boat in theory, set-up and sailing.

The front end felt firmly planted and the pod wasn't flying... but then it doesn't get light until over 42-3 knots. All in all it was a pretty good run for the intended purpose.

The mean average wind speed was 19.18 knots, peak speed was around 41.4 knots with a 500 meter average of 38.62 knots.

It would have been better to have slightly less wind so that I could have sheeted everything into their proper angles without going ballistic.

Despite doing a clean run, we headed back to the shore to digest all the information and double check that everything was as it appeared. So far so good.

The recent rains had caused some of the normally dry river beds to run. The local waterboard seems to think its clever to put all the bore pumps in the middle of the river beds. When the rivers run... all the pumps get washed away... and the town runs out of water. So no water for the past four days... or even for the next week or two apparently. I would hate to be running a restaurant or hotel.

So this is the most complete team we have ever had down here. It's really good to also have access to off-site team members like George and Richy to help digest the pile of data we get after each run. The project as a whole is really powering into this final push to the summit. I hope the summit really is as close as it feels.

Cheers, Paul.

The soldiers line up!
Thu, 19 Feb 09 11:02

Greetings everyone as all the pieces begin to drop into place for no doubt another action packed VESTAS SAILROCKET speed session.

Tomorrow will mark the beginning of our second WSSRC ratified assault on the World Outright Speed Sailing Record. The rest of the team are currently on their way across the 400 odd kilometers of desert from the airport in Windhoek to the operations base here on the coast in Walvis Bay... along with Mike Ellison from the WSSRC.

We have been busy here co-ordinating all the bits and pieces necessary for such an attempt. Helena has been beating down the logistical mountain and chasing all those who need the whip...whilst I have been preparing the beast for what is to come. This has involved the careful modifications and fitting of the new curved main foil. It's quite a detailed process. Fitting fences is always a fiddly process on a straight foil let alone a curved one. We have three fences fitted at various angles and depths down the foil to prevent ventilation (air getting sucked down from the surface at high speed). Actually fitting the foil to the boat takes about a day and a half as we have to be very precise with every angle. The speeds and forces we are aiming to deal with are going to push this foil to its limits. In order to average around 51 knots down a course... we will need to be ready for peaks of around 55 knots, maybe more. Errors of a fraction of a degree will have a noticable effect. The lawn of the Walvis Bay Yacht Club was littered with Laser levels, digital inclinometers, rulers, foil alignment jigs and computer angle sensors. I hope Malcolm doesn't want to change anything in the near future as it is a long winded process.

The old and the new. I'm back on the '0' carb diet to get below 75kg's (1 more to go)

There has been very little wind since we arrived leading some of the locals to question what we are doing here. I'm glad to say that it has returned. Yesterday was a glamorous day wind wise... but the tide was low... so strictly one for the windsurfers. Today it is going to honk!!! It's windy already and I reckon it will hit near 30. Good ol' Walvis. Looks like we have hit it spot on. We have been here twice before at this time of year so we know it blows.

New team member Alex adams from Weymouth has been getting to grips with the boat as against his normal steed which is a Foiling Moth. This is going to be an interesting couple of months for Alex.

He can be seen here touching up the 'Down' flaps on the inboard end of the beam which will help keep an aerodynamic down-force inboard end of the beam at speed. You can see the larger outboard flap near Alex's left shoulder.

The wing-sail has been shrunk down with a heat gun and we are preparing to fit it to VESTAS SAILROCKET before it gets too windy. We hope to be ready for sailing tomorrow but we won't quite be in record setting mode as we will need to dial in all the rudder/control systems to the new foil. Hopefully we are heading in the right direction with this one. It might take a few days to get it sorted... but once it is, bloody well look-out because we're not going to hold back. We are here to finish this once and for all.

Let's see what happens,

Cheers, paul

Good to be back in the Bay!
Tue, 10 Feb 09 14:29

Well this one comes to you direct from the hot-seat in the container at the Walvis Bay Yacht Club. We managed to duck through the snow storms in the UK and arrived safe and sound in the sunshine and heat of Namibia. There has been very little wind to date... but it shows signs of picking up.

 One by one we start the process of 'spinning plates' again. There is a lot to organise.

Here is just a short one to let you know what we are up to and what the plan is.

 For those of you who are not fully up to speed, On the 3rd of December, 2008, VESTAS SAILROCKET began collecting records by setting a new 'B' class world record of 47.36 knots over the 500 meter course. This gave her the unofficial title of the worlds fastest boat... but still 3.21 knots short of the Outright world record currently held by the kitesurfers. The team took VESTAS SAILROCKET back to the top of the course with a view to the Outright record. On the following run the craft lost 'pitch stability'. The nose lifted up at near on 60 mph and the shooting match performed a spectacular semi-loop. No-one was injured and VESTAS SAILROCKET was back in action around two weeks later. Un fortunately the good winds required for a record attempt had gone and the team decided to pack up and return when conditions would be more favourable (hopefully now). Around 16 days after their success, the Australian Macquarie Innovations team took the un-official fastest boat title by averaging 48.11 knots. The objective of the VESTAS SAILROCKET project is to get the outright world speed sailing record so they have returned to Walvis Bay, Namibia in 2009 to do this. Every record we get on the way official or un-official is a bonus and enjoyed in the appropriate manner:)

Helena and I arrived back in Namibia four days ago and have been arranging things for our next record attempt with VESTAS SAILROCKET.

We have booked our second WSSRC ratified record attempt to begin on the 20th of February. It will go for 28 days. we have put aside three months in total for the whole session.

We will have a strong team down here as we have seen the benefits of having good people working on all aspects of the project. We need to focus on all aspects of the program during these runs and not just the boat. Our recent success wouldn't have had a fraction of the impact if it wasn't for Helena and Brad doing such a good job of recording the events.

The team at DesignCraft have built a new stronger curved foil which we will fit to VESTAS SAILROCKET mainly in an effort to make  the craft safer at high speed and prevent the nose from lifting off again.

We want to have everything in place and functioning perfectly for Day 1 of the record attempt.

So that's about it. I believe that the  Macquarie Inn. team is also carrying on with their  attempts down in Sandy Point, Australia. Hopefully the bush-fires aren't affecting them. My home town of Healesville is right in the thick of it all and friends I have spoken to today are on the front-line. You have no doubt where your real home is when events like this befall friends and family. Good luck to you all.

So get ready for more thrills and spills party-people because it's about to all kick off down here once more.

Cheers, Paul

Ding ding, Round 5... It's on!
Thu, 29 Jan 09 13:05

Righto, we've had enough of the wonderful British weather and it's time to head back to Africa and fire VESTAS SAILROCKET up for another record attempt.

Whilst it's been kind of the Macquarie Innovation boys to be keeping the seat warm for us, the constant media bombardment from their overactive PR machine is too much so we will have to get back out there and set things straight;)

Those guys were a huge inspiration to me through some pretty formulative years. Way back around 1985-86 when I was racing around Port Philip Bay In Victoria, Australia, we would cross paths with their incredible and awe inspiring C-class cats. I'll never forget during one of the VYC OAKS (One of a kind) races where we were representing the Hobie 18's and Victoria 150 joined in. It was a four triangle course and they started five minutes behind us... and lapped us twice. The grace, the whistling, the hull flying an trapezing on the very broad downwind leg... it blew me away. Years later and way North in Airlie Beach, I chanced across a copy of Bernard Smiths 'The 40-knot sail boat' whilst working in a yacht chandlery. It was a chance encounter that would ultimately change my life. One of the other things I remember of that job was that there was a poster promoting deckgear on the wall showing Yellow Pages Endeavour in full flight. I ended up laminating that picture and still have it to this day.

I think its great that they are still hard at it. I must say it amuses me that after 15 odd years of concerted effort that they waited a mere 16 days after we finally topped them... to finally beat their old time on YPE. Well, you get that. I am confident that we can wring a few more knots out of VESTAS SAILROCKET and hope that mother nature is kind to us down there. Whilst it was fun and a great relief to pop out on top of the boats with our first record... we must remain focused on the real goal... the Outright Record. we haven't made the summit yet. It looks like the Hydroptere team will be out of action until April some time but like us, they will have learnt from their crashes and will probably come back better for it.

The whole challenge has been one of control and I still believe we have the most stable craft. Sure, that flip might indicate otherwise but we believe we can approach that problem from a point of understanding and safety. A new main foil is currently being built at DESIGNCRAFT and will be fitted for future runs. It has a few detail changes but is slightly curved as well. PI RESEARCH are servicing all the electronics as we work together to make the perfect system which is ruggedised for the harsh environment it experiences. The TRIMBLE GPS system is back in Sth Africa at OPTRON also getting a service. It's amazingly tough stuff and we are grateful for this as it was submerged in salt water for almost an hour after the flip and survived unscathed. If it hadn't... we would have lost the run.

Malcolm and I went over to the Isle of Wight recently and did a few presentations to VESTAS. It was really nice to see familiar faces and the genuine interest from within the company. There are people there who have followed us from the very beginning as they were building blades downstairs... and we were building VESTAS SAILROCKET in the same shed upstairs. I was looking through some old back-up hard drives the other day and went down that ol' memory Lane. So it's great that they are sharing the journey with us.

OK, that's enough... back to sorting out the logistics.

We will, as always, keep you posted.

Cheers, Paul.

OK... now it's over... for now!
Mon, 29 Dec 08 16:12

...And it's been a blast!

So we didn't quite get the conditions we were hoping for yesterday. Close... but no cigar. We went and had our first crack at the nautical mile in winds which were gusting from 15 to 21 knots and a little west. I had to start around the corner in second lagoon as the Walvis Speed-spot is only 1.04 nautical miles long and I needed to hit it at speed. There wasn't enough wind to blast VESTAS SAILROCKET up to speed before the course in a short amount of space so we had to carry the slow start up speed in our nautical mile run. Once up and away I got everything sheeted in, the wind angle readout had played up at the start so I had to guesstimate the wing angle. There was alot of spray off the front planing surface due to the increased downforce we had put on it after our flip. Visibility wasn't good. I could feel the accelerations and de-accelerations as I dived through the gusts. Sometimes it felt fast, sometimes not. I couldn't see the end of the course and had to line up on things in the distance. When I guessed I was off the end I hit the flap release and spun into the wind... but still ended up out in the lagoon. I had peaked at 43.11 knots, done 500 meters in 41.68 knots, 1000 meters at 39.6 knots and the nautical mile at 36.8 knots. A good first try in moderate winds but nothing earth shattering.

I ran off up into the lagoon until I hit a mudbank in the middle and everyone came in the RIB to help me lower the rig. We had to lift the hull of VESTAS SAILROCKET onto the RIB and walk it back out of the lagoon.

The sunset was magnificent.

And that is how our first world record attempt ended.

I was happy that we gave it our absolute best shot. We got some records and leave as the fastest 'boat' in the world... but the one we want the most, the outright world speed sailing record, remains in the hands of the kiters.

We will have to come back for that one. And we will.

Overall it has been a brilliant four and a half months with one challenge after another. We conquered our steering problem after a big crash, had another crash whilst perfecting it... and then things started to happen quickly. the speeds went through the roof and did so all the way until the boat itself tried to go through the roof. We repaired her literally in record time and came back out for more. The wind denied us in the end but then we knew we were making an attempt out of season.

We will leave Walvis content yet restless in the knowledge that it isn't over.

VESTAS SAILROCKET is now fully packed up and as I write this we are getting set to go for one last blast down the speed-spot... on windsurfers. We will just go for fun and enjoy this amazing spot.

Thanks to everyone who has helped. You know who you are. Our success is shared and only possible because of a collective and overwhelming force.

Cheers, Paul.

Over at speed-spot for one more shot!!!
Sun, 28 Dec 08 16:08

Well the operations base is now the timing hut on speed-spot. We have a full team and it is close... so close to being run-worthy conditions. The wind is gusting to 22 knots occasionally but generally around 19 knots mean average. The bigger issue is the direction. It is still around 15-20 degrees too far west. A slight change in these two key parameters will see us all spring into action. We are watching the windsurfers and getting their feedback off the course. It agrees with our Tacktick instrumentation. We are hoping that the SSW wind begins to lock in towards sunset. If it does, we are ready.

We will try and make one run... our first ever shot at the nautical mile!

cheers, Paul.
