Fencing the new foil....
Hiya all,
Well the discussion between Malcolm, Richy and myself has lead to the fitting of three fences 100, 250 and 400 mm down the span of the foil with the first one angled at 2 degrees, the second at 1 degree and the third at 0 to allow for the waters deflected flow off the planing surface above. Making, fitting and shaping the fences took the best part of yesterday. This morning it was all fitted onto the 'rocket' and carefully alligned to make doubly sure everything was where it should be.
It looks pretty cool... in a modern F1 car sort of way. Lots of ultimately draggy crap everywhere that nonetheless looks 'purposeful'. I'll reserve judgement until I see the end result. Malc didn't want to insist on fitting the fences... but he persisted with the reasoning until I relented and pulled on my 'boat-building' hat.
It's a glamourous day here in Walvis Bay. Perfect for our purposes. It's always annoying to miss these days... but I'm delighted with the progress we have made in the last week. It's all vindicated some of our recent choices to fit a much more complex data collecting system. When you ask for the 'lights to be turned on' in a gig like this, be prepared for what might be revealed as it mightn't be what you expect!
I'm itching to get out on the water again and pray to mother nature to send us another day like today.
I know we can do this. When this boat finally lights up it's going to be a beautiful thing.
This afternoon I have to work out a system to lock off the steerable skeg-flap when I'm not using it. Malc reckons that the skeg is only 30 % efficient with a free trailing flap. This could be the reason that sailrocket is 'dropping' into a stalled state at the beginning of the run and remaining there for the duration... just a thought.
Righto...
Cheers from the Pelican Bay resort coffee lounge (our 3G card ran out so we come here for a wireless connection)

p.s. Brad, found the plug spanner... the plug was way loose!!! Took her out, cleaned her... first kick every time! Helena gave the bike the mother of all clean-ups and now she looks sweeeeeeet! Happy days ( I told you it was a glamour day).
