Run 53... right on the button!!!

Firstly, thanks for the comments on our come-back runs. It's nice to know that people are listening. I'll try and answer them all a bit later.

Today we were fortunate enough to have conditions almost identical to yesterday. This is a rare occurrence and allows us to accurately assess the small changes we make between runs. Yesterday I found that I was going down the course using nearly all the range of the skeg-flap steering to stay straight at speed... but there was next to no load on it. according to 'Malcs Calcs' and my Mk 1 'eyeball', this indicated that I had biased the fixed part of the skeg a little too much to make VESTAS SAILROCKET bear away i.e. the trailing edge was too far to leeward. Now we are not talking big figures here as we have to remember that we are still doing near on 40 knots and a degree really matters. The main foil itself works at around a 2 degree angle of attack at high speed!

The data we recieved of the PI RESEARCH logger and B and G sensors showed skeg-flap steering angles of up to 11 degrees. Today I dialled the fixed part of the skeg back two turns on the adjuster and left everything else on the boat identical. today at speed I saw angles of around 2-3 degrees, a top speed of 38.5 knots and a wind speed averaging around 17 knots at best. It was the best steering that the boat has ever had. the large rudder was up, the spray was down and the wing flap was mostly in. It was a very clean run all in all.

I called malc to let him know. Ideally this is how speed sailing would go... in an ideal world... One variable at a time, but as the great philosopher 'Ice-T' once said..."S**t aint like that". Sometimes the 'suck it and see' approach has to take precedent over the scientific method if any progress is to made in a realistic time-scale.

Now let's see, a quick whip through the comments...

yep Adrian, we are looking at all aspects of the wing... but we have to see what options we have left to make the existing one more benign first... or even if we really can just sail around its weaknesses. The only time it came unstuck recently was when we had a significant and totally unpredictable blow out. Of course it might happen again. Chris and the guys at AEROTROPE who did such a brilliant job of engineering the current wing are looking hard at our options. If we make a MK2 wing... it will be made with a view to a Mk 2 boat... and hence higher speeds.

There has been a lot of blah blah and not enough pics/video etc. I totally agree... but our team down here at the moment consists of Helena and I. When we bring a video/media guy down here... we need a boat builder. When we bring a boat builder... guess what? the good news is that everything has been photographed and video'd (ask the guy who stole my laptop from beside my bed whilst I sleapt the other night) and is backed up on a hard drive. Every run has a huge amount of data and it is all archived. This alone is a job for one person. Now that the boat is fixed, I'll get back onto it... and even show you the crash footage!

For the record, I think that WotRocket is great and I'm stoked that they are out there and going for it. Rivalry is a great motivator. I wonder about their concept alot... because I simply don't understand how they are going to back up the claims. I figure there simply must be more to it than meets the eye. We shall soon see.

VESTAS SAILROCKET is a peak at where we feel the future of the speed sailing will be. We still have full faith in the concept. If we ultimately need a Mk2 boat then so be it. I don't think we are at that stage yet as this little beauty still has a lot to offer. Every day we learn more and the project moves a little closer. MI, Hydroptere and WR all have limits of one sort or another... and no doubt theories on how to overcome them... we watch and learn from all of them. Aspects of one design can be incorporated into another. If WR can make super cavitating foils work on a boat with a limited righting moment... then sure as hell we can too ( of course we are looking into it irrespective of who else is doing what). It's not a new topic to anyone looking at going over 50 knots.

We haven't put out a lot of press releases recently... but this blog has always been open and honest about what we are doing, feeling and thinking. If anyone wants to take the content and use it then feel free to. we like to spread the love. We are at a stage where we like to speak with results rather than press releases. It is funny how the publics mind works though. I remember the interest we drew in Weymouth... after we had been on TV the night before! Before that moment people would just walk by as if we weren't there. Two minutes on the box and all of a sudden voila... we must be serious! When we make a significant gain... there will be a press release. I actually really enjoy writing them...but I have seen so many that turn into nothing... that I don't read them that much anymore. Anyone can make a big claim and get some easy press... and because it's on the front page with a glossy pic, a lot of the readers think it must be real and virtually a done deal. this is a very humbling past-time.

Cheers, Paul

p.s. I know, I know... more pics. I promise you ten by lunchtime tomorrow... how's that?

Runs 51 and 52... the stress and dust get blown away!!!

Well it was with great relief that we re-launched VESTAS SAILROCKET today. The stress of what we are doing has been getting to me over the past few days. yesterday I snapped a little. A seemingly unsubstantial thing happened and it pushed me over the edge. I knew today was going to be our 'comeback' day and I felt the presure of making it go smoothly. A crash on top of a crash does not make a cake that anyone wants to eat!

the whole boat needed to be recalibrated and it was during the very last twist of a screwed thread which was to allign the whole boat... that it happened. A pin started binding up in a hole and then it quickly siezed. It had never done this before. I tried all the tricks but it refused to budge. I had no option but to apply more force... but then the carbon laminate cracked... and I knew that the clock had begun ticking between the now and the then of the next run. It was too much after a major repair. All the work done on the days calibration was ruined as whole new brackets needed to be fabricated which wouldn't necessarily be positioned where the last ones were. It meant we were rushed. rushed on an area which I really didn't want to be rushed on. We strive above all else to keep this project scientific. to change one variable at a a time, improve our understanding and eventually dial this boat into its predicted potential. What we don't want to do is just rush it back out on to the water every time to show we can come back with a mere sailing boat. Sometimes we have to compromise. This is speed-sailing and you have to grab weather windows when they come. Some times you have to use the best of your abilities to 'have a stab'. I didn't want to have a stab straight after a significant crash... so I worked... and stressed... and my mind was full of a million things that needed attention.

 Walvis delivered us the perfect day. Not too light and not too strong. We did two runs in conditions that always make the boat look good. We peaked at 39 knots and all the modifications felt absolutely fantastic. All the data PI RESEARCH and BandG sensors worked brilliantly. the data will be excellent and pave the way forward.

All the stress just washed away with the dust from the repair.

It's behind us now.

Certain e-mails in my outbox will not be sent.

Aspects of the project need to be addressed... but we can do that.

Today I sailed nice tight courses with the new skeg steering system and a new method of sheeting the wing. It worked and felt good. It was with great joy that we put VESTAS SAILROCKET safely back in her soft hangar.

 Meanwhile I watch the progress of the other teams chasing the 50 knot goal. For sure the Hydroptere team looks the most impressive. These guys have done the hard yards and deserve every knot they get... but nothing in this game is automatic. The other team making claims from Australia give us a few giggles. I don't think they have done 5 knots yet... but they consider themselves contenders and are rushing to call in the comissioners!

Don't get me wrong, 'they' are one of us and I also laugh at some of our own early press releases and promises. This is a loooong road. Hydroptere started as a model in 1983. yellow Pages performed extremely well very quickly... but the same team haven't managed to re-capture or improve on the record in 15 years of trying... and it has taken us nearly 4 and a half years of dedication to even post a 40 knot average! If the WotRocket team can get anywhere near 50 knots in the next year... let's say above Hydroptere's current 500m average ( which I'm sure they will smash in the coming weeks) I will sail our boat down the Walvis course naked (and it's not real warm here either)!

There it is! Claim for claim. I'm glad they are on the water and I admire their confidence. I can understand the theory behind Hydroptere, MI, Technique A' and Longshot... but that one escapes me... Maybe they are holding back on some of the real facts. If so, fair enough.

Meanwhile we will continue to push on with what we know.

 All I can say is that the boat felt great... and it felt great to be truly back. We can only progress in a careful and methodical manner until we unleash the boat that we know is within.

Desire is something you want, passion is something you can not live without.

This one takes passion.

Cheers, paul.

VESTAS SAILROCKET is back in action (or is it to a state of chaos)?

Well, we are back in action. Rigged and ready for sailing!
Aye yi yi... what a hectic couple of weeks.
We said we would be back in two weeks and we are.
The fact is that although the main breakages were repaired relatively quickly, it was the detail work that brought our enthusiasm to a crawl. This brought it home just how sophisticated our once humble little speed-sailor has become. Once we just had one simple rudder hanging off the back with a line from either side to steer it. Now the back of VESTAS SAILROCKET looks like it should be probing the surface of a foreign planet!!! There are sensors, skegs, rudders, flaps, fences, pull ups/pull downs... and even a good ol' bung in there to remind us it is actually a boat.

Every aspect of the boat has gone up a level. Everything is custom made and then evolved to better serve its purpose. Everything is more complicated. It actually blows me away what we have created. We have had a lot of time during the repair to reflect on many aspects of the project. I personally love this boat and know it more intimately than anything I have ever known in my life... but it must be fit for purpose.

We must share the same dream.

That means that the creature at the core of this boat must be as willing and capable of achieving the end goal as we believe ourselves to be. If it is not, then our paths are destined to part. We must remain impartial to the boat and attached to the goal. I know that the concept underlying VESTAS SAILROCKET is the future. I know it's right. I totally believe that this boat is a brilliant Mk 1 interpretation of that concept. It is the first version to live out 'Bernard Smiths' vision of a '40-knot sailboat'. In fact it is already probably the fastest boat ever to come out of the UK (perhaps unfairly excluding wind and kite surfers in this context... but for the sake of the point I'm referring to a boat and not a board).
But we are yet to see if this version is going to take us all the way to the goal. WE NEED TO FIND SOLID, RELIABLE AND CONSISTENT CONTROL! We shouldn't be punished for every little indiscretion we make either. The wing has been a handful from day 1. It is an unruly beast. One that is in it's element when blasting down the course but a handful everywhere else.
We have not exhausted the design solutions for many of our problems and continue to research them, experiment and modify as best we can. We always dreamed of getting to this stage of the program where our problems were high speed related. Well, we are here... and every windy ride is absolutely thrilling for all the team on-site. The video from our last days sailing have kept all the locals talking. I will share it all soon.

I apologise for not posting a lot of content about the repairs and decision making process but any time not spent here has been spent on re-building the boat. The fact is that we have been incredibly busy getting the boat back into the shape it now is. It has occupied my time and thoughts every conscious moment.

She has a few knocks and bruises now but she is still our pride and joy. We will give her the best shot humanly possible of being the fastest sailing boat in the world. With every scratch and modification we infuse more of our own souls into her.

The title of this post??? A great little chap from the island of St Helena came by today to help out in case we got onto the water. He has spent a great deal of time out on working fishing boats and despite being pretty young, he has already done two circumnavigations. He has a quick eye and knowledgeable understanding of what our problems are. As we finished the last intimate little details of our repairs he commented on a philosophy he once heard from one of the engineers onboard a boat he spent a lot of time aboard. Jonathon said how the engineer believed that the natural state of anything mechanical or electrical is not a functioning one. Working smoothly, as we humans desire these things to be, is not the state that they aspire to. Hence the engineer went on to say that those rare moments when everything is indeed working perfectly are actually moments of chaos and disorder that require constant outside attention to maintain. I can't argue with this logic.

So it is today... that VESTAS SAILROCKET has returned to a state of chaos and disorder... and is sitting outside once again. She is fully rigged and ready for battle. Significant improvements have been made to the skeg-flap steering system thanks to 'Fi-fi' and Alan Louwe he leant there skills and equipment to machine up some fantastic new pieces which are both beautiful and fuctional. All the play in the previous system has been removed and this has allowed us to remove certain problematic systems and incorporate simpler designs that will makemy life in the cockpit much easier.

So the last crash is never behind us until the next run vindicates our decisions and solutions.

Hopefully that day will be tomorrow. Hydroptere has begun its world record assault in earnest so the game is afoot.
I can't wait to get back out there.

Stay tuned, tomorrow looks a bit light... but we will be ready.

Cheers, Paul.

Repairs going well, back sooner rather than later!

Hi all...

well as you can imagine, it's been a pretty busy week here in the container. The beam has been structurally repaired and has 'left the building'. The wing was repaired outside and is now inside the container ready for re-skinning tonight. The deck, the skeg, the rear planing surface, the bottom of the cockpit and the wind-wand have all been repaired. The long list of jobs is being rapidly worn down with only one more serious lamination to be completed.

The re-assembly of VESTAS SAILROCKET will commence in earnest tomorrow. I want to be ready for sailing on Sunday.

Overall the repairs have gone well and the container has supplied us with everything we have needed. I'm pretty happy with our modest but efficient little operations base. The Walvis Bay Yacht Club has just been fantastic to date. We simply couldn't have wished for a better location and environment to work in.

On the forecast, for what it's worth, Monday is shaping up to be a nice day... for both wind and tide. There is a lot of detail work to be done to make sure we can make the most of a great day if it comes. We are starting to go pretty quick all the time now and have to pay attention to detail. That last crash highlighted that point. Look at everything again. It is at this stage of the game that your priorities shift from saving weight to gaining strength!

Righto, Helena has begun on the wing so I'd better go and help. Pics tomorrow.

Cheers, Paul
