I'll second that. We want to see what you're up to, Nigel. Even a few pics of the crew having a cuppa just to let us know there are real characters bashing tin down there.

Your comments about the Quicksilver website are correct. I agree that it looks pretty good, presentation-wise, but could do with more depth and more regular updates, and I think those things have begun to be addressed over the past few months. Our graphics specialist, Richard Ainge - one of our many voluntary helpers - is currently in the USA on a fortnight's business, but when he gets back we can get some new stuff he's been working on onto the website and keep things moving forward.

With regard to your comment, Bill, about the guys in our team and wanting to see more of them, we have begun to address that. Ignoring the brief biog about me in the "Team" section of our website - which came out of the Arc and needs to be updated - there are now brief biogs of several of the technical guys in that section: Dr John Challans, Simon Connell and our engine man, Graham Pool. To these three we will shortly be adding two more: Ray Freeman and Tim Harrison. These short biogs give some idea of who our people are and what they do.

And there are many others. These guys really exist - promise! And just like you guys, we stop for a cuppa and a sandwich at lunchtime - although cheese and tomato paninis currently seem to enjoying greater popularity than the traditional bacon butty! Most of our work gets done off-site, and we seldom get together more than once a week, as we have guys all over the country and the travelling would be impractical. The work we do is, for the most part, very different in nature to what you are doing on the K7 restoration, because our main emphasis is on designing the craft and its related systems; we don't do masses of manufacturing, because the components themselves are almost always made off-site by specialist companies that are working alongside us.

For us, designing involves an awful lot of discussion - and sometimes some disagreement - and then a fairly hefty amount of actual design work, then, in 3D CAD/CAE, then the part in question can be made. On Friday, we took delivery of the actuator for the electronic throttle. It is an off-the-shelf component, but it took a heck of a lot of research and debate to settle on what we needed to do the job, and - even then - the component will be modified by us in a fairly significant way to make it fit our criteria, as it fails in the open position and we want it to fail closed.

As time goes on, I'll try to give you guys more of an insight into what we do. Hopefully, our website will do part of that job for me, too. There is a lot more material we would like to get onto the website and this year will lift the veil on a lot of it.

This is not a criticism, it's that I just don't get it...

Why not use a simple throttle linkage with a nice, fat spring? The aircraft didn't have anything particularly fancy in that dept. and it flew happily for many years

There is a bit of a mix-up occurring, Mike, in that no-one should think that Quicksilver is "computer-controlled" just because it has a computer on it. I have complete control, as driver. The computer doesn't drive the boat, I do. Using electronic controls for the throttle, steering and water-brake is simply a whole lot lighter solution, and easier to package, than a cumbersome series of systems comprising of mechanical push-rods, rockers, springs and so forth.

You are right, Bill, that Buccaneers worked fine without such things, but that is a bit like saying that Grand Prix cars in the 1950s worked fine with wire wheels, so why doesn't Jenson Button have wire wheels on his McLaren now? Building an all-new WWSR boat offers the chance to use technology that wasn't around in the old days and can do a much better job.The modern electronic systems take a bit longer to develop, but once they are working well they offer some worthwhile benefits. One key difference between our boat and, say, the Buccaneer - or K7, for that matter - is that our cockpit is off to one side in a completely separate, detachable module (sponson), a good distance away from the engine and with a 90-degree dog-leg in between. That makes a mechanical throttle linkage - and the steering and other control runs, too - very much more convoluted, and therefore less sensitive, than you would ideally want. Whereas electronic systems are very elegant, in that you simply route a length of electrical cable through the boat - twisting and turning its way through holes in bulkheads and what have you - and there are no linkages, to speak of, at all.

Having said all that, we aren't using technology for technology's sake. Where we can use a mirror instead of a camera, we are using a mirror.

Like I said - I just didn't get it but if the cockpit is out there on the sponson (thought that idea had been superseded) then it all makes perfect sense. Thanks for explaining.

I'm a little confused! The version I'm looking at - which I take to be on the current version of the website - is a conventional triplaner with twin fins, a horizontal stabiliser and a centrally-mounted cockpit in front of the engine intake. Have I got this wrong?

You know what, I've had that version on file but was (obviously mistakenly) directed to the old URL on a recent posting on 'SRG' Forum!!

Somewhat confusing might I say ----.

Indeed, earlier in this thread I posed some concerns as to the absence of a horizontal stabiliser on the current design. Also, I can only agree that the cockpit in a sponson is going to make for a rougher ride for the pilot as it's further away from the centre of gravity.

Furthermore - and I have to admit I'm judging this from the illustrations on the site - the 'stability triangle' looks very narrow indeed i.e. the distance between the forward points (the base of the triangle) in relation to the distance to the rear point at the transom (it's height). This would tend to make the craft less stable laterally i.e. more susceptible to disturbances from the side. Perhaps Nigel might enlighten us?

How about a clever idea in case she crashes? the sponson breaks off for and easy rescue? A sudden stop on the nose doesn't mean a big engine hitting you in the neck?
If she 'tramps' [BB] or 'walks' [SOA] then Nigel will have a sore bum if it gets too rough.
I seem to remember that the sponson version was going to be Dash 1, with observers/equipment in the other sponson and then a conversion to Dash 2 for the attempt..Am I right Nigel??

There's a lot of good responses there, chaps, so many thanks and I'll try to get onto them one by one as time allows. The easiest one to deal with for now is the website issue. I've heard of this before - that there is an ancient version of our website out there somewhere.

I will ask someone to look into this to get to the bottom of it once and for all. I must say I have never encountered the problem myself. As a test, just now, I keyed-in our two website addresses - www.quicksilver-wsr.com and www.quicksilver-wsr.co.uk - and the websites that came up in both cases were the current, correct ones (precisely "mirrored", one to the other, as they should be).

Of course, I cannot control other people's websites that are carrying ancient, obsolete links. With the long history of our website - nearly 11 years - and the various helpers that have been involved down the years, maybe some gremlin or other crept in, so we'll see if we can work out where he's hiding.

There is still something funny happening, Nigel. If you enter via:

http://images.google.com/imgres?imgurl= ... tart%3D440

then that version of the site is still active as I downloaded the file of the picture of the original design (hence my posting earlier up the thread) and somewhat mysteriously if you click on 'Latest News' one gets the latest update on 24/12/09 ----??
