A very promising day today as VESTAS Sailrocket 2 thrust the team effortlessly into the fridge for the 30 knot bottle of Pol Roger champagne. Nice. I'm not going to even try and dramatise it as it felt so cruisy and natural. VSR2 is simply dropping into her element and she feels right. I have no doubt that we will just as easily knock the next bottle over. Damn she felt rock solid. Like a grunty car slipping into top gear at 50 mph... you know a whole world of speed... I just said I wasn't going to do that. It was cool though.

We woke up this morning to a text from very good friends Martin and Henda who are living on their yacht out on a mooring in the Bay. They told us that the SW wind was already blowing and to expect wind this afternoon. It is extremely unusual to get a SW wind first thing in the morning but nonetheless we hit the Yacht club expecting to sail. The wind didn't abate so I pushed the guys(and girl) to get their jobs done and focus on getting wet. The afternoon high tides have left us and we now have to go out around all the sand bars at low tide. The water is having some sulphur 'bloom' thing going on so it is milky aqua, very cold, starved of oxygen and smells of rotten eggs. The fish can't breath underwater so the birds have a field day grabbing them all on the surface. It's a Walvis thing.

By the time we got over to 'speed-spot' it was gusting to 25 knots and by the time we got the wing up it was hitting near 28. I decided to hold and the wing came down. Whilst VSR2 should be able to sail in these conditions, so much is getting added on and modified between these early sessions that it is simply too soon to push. The cockpit has been changed immensely and all the COSWORTH data loggers and their associated looms are now crammed in there. I have to get familiar with it all and comfortable enough to know the sequences when things get heated. Today was supposed to be a day to ease me into this new cockpit... not throw me to the speed sailing lions.

So we stood down and waited. I'm getting a good feel for this place now. I refer to local knowledge but don't assume it's always right.

We got it pretty much spot on today as we hit the course a couple of hours later and at pretty much the ideal time. The wind was 17-20 knots. I went through the ropes on the tow up the course and felt semi-confident I could get them all right. The new systems did their jobs and we sailed over the 'hump' quite easily once again. I was now sitting down in the forward facing and angled cockpit and quickly became aware how weird it was not to be able to see the boat and sails ahead of you. It was great to have the COSWORTH instruments in the cockpit to reference the wing and rudder angles. I sheeted in from the start up settings and VSR2 just shot forward. She was no longer mushing but was now riding hard and firm on the surface.

 

 

 

 

You can see that the top wing section wasn't sheeting in properly and was in fact fully eased. In fact there are a number of details that will make the wing significantly more powerful... but once again, pure speed was not the objective of the day. Preparing for pure speed was. The steering response was fantastic, all the controls worked... but some need to be tidied up. The ride was clean, spray free... almost majestic compared to our first boat. I used to get hammered by spray at 30 knots but not in this boat. I knew we were over 30 knots and finished the run early as it was low tide and the shallows at the end of the course beckoned.

We tried another run before sunset hoping to bag the 40 knot bottle but a detail slipped through the net and we weren't able to go for speed. By this time it was dark and we were happy to head home.

So it was all good. The work we had done in the week between sails had all shown its worth and the week ahead lies openly beckoning us to give it a good 'nudge'.

I think tomorrow is going to also be windy so let's see what we can come up with.

I'm now tempted to jump straight to the 'funky' foil to see if it too can jump through the hoops. It is the foil for which VESTAS Sailrocket 2 is built so why not get it out now?

Looking at all these photos of VSR2 sliding along now... well it's just plain cool. It's working. It's coming to life. It is a ship at heart and it IS going to take us to amazing places. I love having it in my life and this is exactly where I want to be.

The team are doing a great job. We are all witnessing our efforts bear fruit. Things happen fast in small, dynamic teams. You think of things in a bar and build it tomorrow. That afternoon it's being tested. The skills in this particular team are very diverse. It's a pleasure to watch them rip into it.

Righto, bed time. Yes, yes... of course there is a video to come... but tomorrows will probably be better;)

Cheers, Paul.

Hi all. Not much to report from the sailing side as we haven't had any decent weather to get out since the first run over the 'hump' nearly a week ago.

The weather is described locally as 'East' weather meaning that it is likely that the East winds will blow down out of the high desert plateau's inland and cance out the normal South West winds. There is a battle going on between the two winds and quite often Walvis Bay is in the middle. The upside is that the days are hot and gorgeous. The downside is that what makes them so gorgeous is the lack of wind. It's braii weather.

Nonetheless we work on the boat every day to get it as ready as can be for the one or two good days that may fall into our lap. We only really have 8 possible sailing days left after which we have to pack up. If one of these days is a good one then we have to be ready to get out there and tick as many boxes as we can.

I want to see VESTAS Sailrocket 2 do reliable start ups and get easily into the 40 + speed range using the conventional foil. We should be able to see how stable she is as she gets faster, get a feeling for the steering and see how well all the systems work. If we are happy then we will do a quick pit-stop and switch in the high speed foil section for the main foil. Whilst we have made it over the low-speed hump, the next 'hump' will involve the performance of the high speed foil and how well it performs in the low to middle speed ranges. It will be fascinating to see how much wind that needs to really get tracking. If we can get that over 40 knots in winds around 22 knots... well, that will be the day I know we will have cracked it.

I have no true idea of how hard,easy or realistic this will be. We have our theory and list of options to assist us... but some of those are costly on many fronts i.e. whole new main foils and we want to be pretty sure of ourselves before we start ordering new ones. They aren't lollipop sticks. If we head back to Europe now not really knowing if the foils are any good then it adds another element of risk to our return session later in the year. We desperately want to get VSR2 up to its record setting potential this year so we want to be chasing high speeds asap.

Time is running out now and we need some weather related luck to fall into our ever optimistic laps.

 

Half the team are working full-time through the complex COSWORTH wiring system. So far we have the basics of Wing and rudder angles working but the strain guage logging system is proving to be.... errr... stubborn. Fortunately Jonny and Helena have a lot more patience than me with boat electronics so I have left them with it. It's all a bit of an uncertain mess now but once they have it sorted then it should get tidier.

 

The cockpit is starting to look very business like. We have the two Cosworth displays sitting to my left just inside the rim of the cockpit. The small diameter, quick release steering wheel has a multi function PTT (push to talk) button on it which activates a really cool comms system which we are helping  MOTOCOMP develop. Basically it gives an absolute first rate wireless, noise cancellation system based on the Interphone F4 units used on motorbikes (which gives very clear voice transmissions even in open face helmets up to high speeds and is pretty much waterproof). The units allow a full two way conversation between the crew which is clear as a bell... and for the pilot to link wirelessly with a VHF radio to transmit off the boat. The fact is that you are often in a windy environment when using marine VHF's and most noise/wind cancellation systems are crap, let alone wireless. This system works brilliantly and is crystal clear. We are just getting started with this. The fact is that this project is a great place to test these electronic products. If they can not only survive but excel in our environment... then I will happily recommend them to anyone. I look forward to having great comms on and off the boat at last.

 

Outside now, I can hear the small Dremel grinder gnawing away at carbon as Ben fits the front seat. All the control lines are now run forward into organisers either side of the steering wheel. It does look a bit weird. It looks like a racing car cockpit and yet it has all these ropes hanging out of it. Yacht, plane, race car.... what's not for a guy to like about this toy?

 

So tomorrow is forecast to be better, as is Tuesday. Fingers crossed  the good winds from the south west will triumph over the evil winds from the East;)

We're ready.

Cheers, Paul.

So here's the video as promised. It's taken Helena some time to get it sorted and uploaded via an African internet... but compliments to all as here it is in HD.

This one puts you right in the cockpit for what was an exciting little ride. Especially as we didn't really expect this to happen.

http://youtu.be/2XwlSQNSR5Y

I was actually holding her back a bit by keeping the wing stalled until I was sure my 'house was in order' if she really took off.

Happy days.

It was a very significant moment for the whole team. Now for the fast stuff.

 

Enjoy the ride. I did!

Cheers, Paul.

Hi all, just a short one to say that we just came back from speed-spot where VSR2 cruised effortlessly over the 8 knot speed hump in mild 16-19 knot conditions. The addition of the back skeg transformed the low speed handling and made VSR2 track true from start-up. A heap of mushy dra was lost and away she went. The boys were following in the RIB and we were all 'whooping and hollering'. I left the wing fully eased and just enjoyed a sedate run. The point we were looking for had been proven. What a great day. We hit just over 20 knots so that means two bottle of Pol Roger champagne are history (the 10 and 20 knot bottles).

The videos and photo's will follow. I just wanted to let you know asap. We are very excited by this. The boat felt great, the rudder was steering, the back float was lifting on the foil... it was simply working.

The champagne is warm as we didn't pre-empt this one. Maybe that's the secret.

What a great thing to witness. I am pretty happy at the moment. I reckon that 20 knot wave that came off the bow of VSR2 today will ripple right through the speed sailing world.

More to come.

Cheers, Paul

Sat, 14 May 11 13:39

Hi all, well we are all cocked and ready to roll but the weather has gone dead flat. We now have two weeks left for this trial session.

We will take this opportunity to take a day away from the boat and head into the great Namibian wilderness 5 up  in our way overpriced 15 year old rental unaffectionately dubbed 'Shite Rider'. The bottle shops all shut at 1 so we'll have to get creative in that department.

On our last sail we still didn't manage to get over the dreaded 8 knot speed 'hump' but we did gain a lot of confidence in the all round handling of the boat. I am now happy to head out in winds over 20 knots andgive it a good push. There is not much point modifying the boat to make it work in the low wind range when everything we want this single purpose boat to achieve is further up the wind range. Being able to get going in light winds is really just a bonus. I'll get concerned if we can't get over it at 22 knots.

The top section of the wing is now on to also give us some more 'boost' and the gaps between the different wing sections are getting sealed to reduce pressure leakage.

A fixed rudder has also been fitted to the rear float to reduce low speed leeway. This was a pre-fitted option which we will now try.

So lot's of things have been changed... enough for now and most of them are low risk.

There is nothing we can do about the weather though so we will head inland before cabin fever sets in. We will head up around Brandberg and Uis where the wild desert elephants hang out. We've seen them a few time up there but with all the rains they could be anywhere.

Hopefully the wind will return on Monday in which case we will too.

At least if we have some time off now, we can push on to the end non-stop to the airport.

The wind will come.

Cheers, Paul.

Thu, 12 May 11 11:39

We made our way out yesterday around 4 p.m. at low tide and through some good wave action which was rolling into the bay. The water clearance of VSR2 is pretty good so she rides nicely over the swells. Walvis Bay is a pretty open bay and there is quite often a lot of swell rolling in around the distant point. It's not uncommon to have breaking waves on the launch ramp. These swells can also be rolling into the end of speed spot and you have to approach this end of the course with caution when sailing. I have hit a wave in VSR1 at around 15 knots which buried the main beam and brought everything to a mushy stop.

Yesterday we set out to see if we could get VESTAS Sailrocket 2 to bear away down the course on her own from a standing start. We wanted to see if we could do it with the beam in the aft high speed configuration. If we could then it would greatly simplify the boat and the whole startup procedure.

We are still getting used to just the basic handling of the boat so every minute on the water is highly revealing.

SPEED SPOT IS A GORGEOUS PLACE AT THIS TIME OF THE DAY. A PERFECT CANVAS FOR A SUNSET.

What we say yesterday, in mild 14-16 knot winds was that by heavy oversheeting of the wing, we could force VSR2 to bear away onto a downwind course in a safe manner. From there I could ease the wing out to around a 30 degree angle and the boat would start sailing down the course... and hold a course. This was great. She pushed along at around 5-6 knots. We reckon that in a few knots more wind with the full wing in place that she would have made it over the 'hump' and up onto the plane. Like I said before, if she can get to 10 knots, she can get to 40.

We practiced this starting/sailing procedure a couple of times and were out on speed-spot until well after dark.

There are still lots of little systems that need improving and each of these will make overall boat handling much better but... we all really liked what we saw.

I think that yesterday I saw that the boat will work... and maybe quite quickly.

 

SO HERE IS THE FIRST SAILING PICTURE OF VSR2. SHE IS SAILING DOWN THE COURSE UNDER HER OWN STEAM. TO DO THIS SHE HAS MADE IT THROUGH A FEW KEY TRANSITIONS THAT WERE SOME OF THE BIG ISSUES RELATING TO THE GENERAL PRACTICALITIES RELATING TO THIS WHOLE CONCEPT. THIS MIGHTN'T LOOK VERY SPECTACULAR... YET... BUT WE ARE ON THE WAY.

It's all so conceptual and unproven that you don't always believe it's going to work until you actually see it.

I think that with a boat this ambitious that you can have two types of fear. One is that it mightn't work... and the next one is that it will work and that means you will have to strap yourself to it one day and take it to the limit! I came away yesterday feeling like we had perhaps just witnessed the transition.

It will take some more testing where the ultimate proof will be when we start from a standstill and get over the 'hump' and off under full control down the course. If we don't need to go swinging the beam and rig around through the start up sequence then that will make life so much easier.

I a still not happy about the general stability of the wing throughout all the handling procedure but we will start working on that. If we no longer have to pull the shrouds in and out around pulleys to swing the rig fore and aft then we can go to fixed standing rigging which is pre-stretched. There is still a lot to do... but maybe alote less to do than we thought before yesterday.

We will try and get out again today. The swell is bigger and the tides are wrong... but this is starting to get interesting.

Cheers, Paul

p.s. I will do Blogs when anything interesting has happened... and when we know enough about what we saw to share it. For short updates I will use Twitter which also comes up on the front page of the site.

Malcolm arrived from the UK yesterday. After a couple of days of maintenance and modifications we hit speed-spot to add a little orange to what was otherwise a grey and colourless scene.

The wing went up effortlessly and we proceded to head up the course to try and go for a sail.

The big modifications we had made was to spend a lot more time configuring the boat as it is meant to be. Sounds easy and obvious... but there is nothing obvious about this boat. What turned out to be right, at first felt wrong. The good news was that it involved a rather drastic move forward of the beam and wing. This will make getting the boat started a lot easier. We also worked on the system to pull the beam further forward to help her even more in the start up phase. We also increased the range of the rudder and made the wing more upright. The friction in the wing bearings was also reduced to help the wing feather i.e. turn 'off' easier.

As we were towing the boat backwards up the course with the wing fully eased, I was sliding up and down the fuselage checking the fore and aft stay tensions. The whole lot goes a bit loose and wobbly when the wind is blowing from the wrong side. We are very far from being comfortable with it all.

It was as we were turning the nose of  VSR2 through the wind that we literally hit a snag. The middle and lower wing sections fouled each other as they passed. The lower section is restrained so now the large middle section was also restrained. The trouble was that the wing was now sheeted on backwards and in this configuration it is not supported by the shrouds. The whole 'shooting match' pitched forward. I motioned for the RIB to yank the nose around which Jeffro duly did. The rig dived forward again. The beam bent and the wing cracked and crunched like a tree about to fall. I was sure it was coming down. There was nothing I could do but watch and wait for the bow to come around.

Thankfully it did. The shrouds picked up the load and the interference cleared itself. We took it all ashore. The part that did all the cracking and crunching was thakfully only a minor piece of fairing. Damn.... my heart was in my mouth. This feeling was supposed to be locked in a container back in the UK with the first boat.

We identified where the interference was and decided to take the boat home to double check that nothing else had been damaged by the unexpected loads and distortions.

It's now the following day and I'm happy to say that everything seems ok. We dodged a bullet there and will be out saling again this afternoon. We opened the wing right up to hopefully avoid any other foul ups. We already thought the clearance was enough but it turned out that a little bit of mast bend would close the gaps up enough at the back of the wing to allow them to foul. Once they fouled, it would increase the tendency for the mast to bend. The whole wing would lock up.

 

We were all very happy to be sitting in 'The Raft' later that night having a beer rather than sitting in the container with a grinder.

It's a new boat and these things will happen. We have three weeks left to start revealing the performance of the boat so are keen to sail at every opportunity. We will try and knock any risky luxuries out of the program that might jeopardise us seeing what we need to see. For now we will just lower the rig between runs until we are totally confident in its ability to feather.

We have a full team here so we are not short of hands. We are not building these boats to sell them... just to prove a point. The focus is on getting up to speed and this shouldn't be compromised... even if it requires a little ugliness along the way.

The sun is finally out and we are about to put the wing back on.

It seems that our drag 'hump' is around 8 knots. I reckon that if we can sail up to 10 knots then we can do 30 knots. Malcolm reckons we will need around 18 knots of wind to do this. It looks like we might get that today.

Fingers crossed and thumbs held.

Cheers, Paul.

In the greyest of days, VESTAS sailrocket 2 headed across to 'speed-spot' with her wing sail in place.

All the little systems, struts and pulleys were in place to get her to the 'arena'. These were all the details I have been thinking about behind the scenes since the boat was first envisaged. When we talk of the design and look at the big issues, in my mind I also have all of these little, real world issues that I know are can carry equal priority in the big picture. I love to see this prior attention to small details pay off. Now they are in place and I know they will work. The boat looks good. It feels good. It's already getting slick.

 

 

VSR2 sits at a strange angle when we tow it. Nothing that worrying as she is so high out of the water. She doesn't tow 'true'. By this I mean that she doesn't tow in the direction of her hulls. This is because she is 50-50 plane and boat and when you tow her backwards across the course.. she just finds a place to sit somewhere in the middle... and that is sort of a big, 'grey' nowhere zone. No problem... just weird.

We got across to speed-spot and headed for the shore next to the two timing huts. Everything has to be evaluated. Do we pull her up on the shore or just stick the forward rudder in the sand and let the rest pivot around it?

 

 

Damn... I could just go on and on about all these aspects as they fascinate me. Every day you get to see all this great stuff come together... and come alive. It's pretty cool and I love it all.

 

We had so much to learn today. It was grey, the Walvis Bay fog bank had come to town... but the wind was steady and perfect for what we wanted to see.

Overall the boat handled exactly as I expected it to. There was no magic where we escaped any of our weaknesses, but equally, the systems we had in place to deal with them were effective.

We could easily hold the boat on station either on the shore or behind the RIB and could spin her around as we pleased.

She sat stubbornly head to wind with the beam raked in her aft-high speed configuration... but began to sail down the course when we raked the rig forward.

The foil went up and down and the lock engaged. The different sections of the wing did their jobs and showed us where they needed greater control.

Yes, we got sailing under our own steam from a standing start... albeit only in a mucshy manner at around 4 knots. The fact is that she probably won't be able to unstick from the water until we have much higher winds so this is no worry.

She looked bloody fantastic and gave me confidence. I know that in these mild conditions that this sense of confidence can be false... but once again, we learnt a lot, will improve the boat and come back out again.

So we put her away in one piece and all felt great about it. We appreciate these milestones and consider them Champagne worthy. VESTAS Sailrocket 2 got her second bottle of Pol Roger champagne poured across her funky bow.

 

 

We will make some changes and try and head out again tomorrow.

She sails... WOOHOO!

Thanks to everyone who has helped. I take time on days like this to appreciate what I am fortunate enough to be in the middle of. I am highly aware of the help our project has relied on and there are times when in my mind, you are all there. You know who you are.

Today was a good day.

The 10-knot bottle of champagne awaits.

Cheers, Paul.

The weather is pretty messy here right now with thunderstorms coming from all directions. As I sit here tapping away in the container, the rain is pouring down outside and thunder is rumbling around outside. I came down in the middle of the night last night due to the onset of strong winds when normally things quieten down. We were awoken by the house dog whimpering outside due to the thunder.

It's all very unusual.

VESTAS Sailrocket 2 sits calmly outside patiently awaiting her first sail. To me she looks ready for it. On the launch day she loked pretty but I knew there were a heap of jobs that still needed to be finished... or even started just to make her remotely ready for sailing. Some of those could only be done once she was in Namibia and the nature of the problem was properly understood. Well, now she is ready... and I am happy.

We have a good team here. It's a real luxury (now it's REALLY raining). I just sent them off on a desert trip as one of the local tour companies does tours in 8-10 BMW X5 4x4's. They often need delivery drivers to take the cars out to meet the guests. It's a great way to get out there and slide around in some pretty cool cars and a nice break from the non stop job list since they arrived. I wouldn't say that the days are hard here but we do go to bed pretty tired. We are on site all day every day but work at our own pace. If we get here early and get the jobs done... and the wind is good around sunset... then we all gear up and hit speed-spot on the wind and kite surfers. The boat takes all priority but then large aspects of the program are weather dependent. You have to take your chill time when you can as the wind machine can turn on and anything can happen thereafter.

So, there isn't a great deal to report until we get to go for our first sail. We were hopng to get out yesterday but we had weather like we are having now... well, not quite this weird.

As soon as things settle, we will be out there. rest assured that no one wants to more than us.

Cheers, Paul.

Mon, 2 May 11 13:52

Here is the link to the previous days towing trials.

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

We are just gearing up now to head out for our first sail... albeit with a small wing. The wind is around 12-15.

This will be a good day.

Enjoy the vid.

Cheers, Paul.
