Conniston - who is going? - Page 2

I don't think he will go this year but he may as it is Coniston and he always wanted to see records back there. He is not well and getting treatment for cancer.

That's terrible!

Well I hope to see him there then.

Can someone please let me know what the dates are for Coniston records week ?

Jon Fuller · 19-10-2005, 08:29 AM

29th Oct - 4th Nov I think

So you are going to miss the V24 record

MrRob · 19-10-2005, 08:23 PM

what day are you doing it?

verytricky · 19-10-2005, 10:02 PM

Gonna aim for the monday and tuesday runs.....

verytricky · 24-10-2005, 06:28 PM

I dug out my certificate from Windermere last year.

On the 15th October 2004 I averaged 74.97 mph over the 1km run. The record for V24 is 75.77 mph. My 'down' time was 75.03 mph, with my 'up' time 74.91 mph...

So 76.00 will get me the record

( you have to exceed the record by 0.3% to claim the record!)

Thursday will be spend polishing the underside of the V24! Then a blanket on the rollers, so the freshly polished hull does not get scuffed in any way, and up to Conniston!

I have to improve on my last years speed by 1.03 mph to claim the record!

Do not polish the bottom of your boat. Certainly not with a wax polish. Fastest is to wet and dry the running surface with 800 paper just where it touches the water when running full trim. If you don't want to do that just leave it as it is.

How does that work?

Techteam · 24-10-2005, 09:29 PM

When a boat starts to run at high speed the friction created between the hull and the water creates heat. Polishes especially wax polishes tend to ball up and increase the friction. Wet and Dry creates a smooth matt surface that actually helps break the surface tension of the water and reduce the friction.

MrRob · 24-10-2005, 09:33 PM

Cool

i have noticed that when rubbing down plugs/moulds, the 1200 w&d finish is Silky smooth and very friction free, on a polished mould there is more resistance even when wet.....

MrRob · 24-10-2005, 09:51 PM

Interesting stuff!

Techteam · 24-10-2005, 10:08 PM

I spent a lot of time experimenting with this. I agree 1200 gives the finest finish as you would expect and I went as low as 600 but generally found 800 to be the best, the extra roughness seems to hold a very fine air barrier. The only time I have ever "polished" was on a painted composite Seebold SST120. We noticed the tunnel and inside of the sponsons took ages to dry. I was working for Porsche at the time and found they were using a 2 part polymer coating to protect the paint on a new car. I used this on the whole of the tunnel roof and inside the sponsons and then wet and dried the end of the sponsons. I am convinced this made a big difference to competitiveness and the boat dried in 5 minutes flat.

verytricky · 25-10-2005, 02:39 AM

So this is serious advice?

Or am I not getting the joke?

I did hear of a Honda boat roughening up the edge of their steps with an addon strip, but that is actually illegal. Would this be considered illegal in any way? What thoughts do you have?

Techteam · 25-10-2005, 10:45 AM

Serious as you like. This is not illegal as you are not adding anything. Blueprinting the hull has been an accepted way of increasing speed for a long time.

There you go then Mike K.

All that "lob" you keep plastering on ,,,,,, leave it rough !!!!!

More time for beer that way,

plus a few minuetts left to spend pumping out the "Abbo" craft!
