Mmmm... the sissy route through the islands to Madagascar eh

I bet it is going to be very nice there. Better watch the Moz channel, though very nice and warm water you can run into troubles there. You can get some info on it here -

He he, I know someone who moved to Tanzania, doesn't want to come back to SA either. Always had the idea to sail up there to Dar Es Salam, say hello with a cold beer and head back (catching fish as you go )

[masalai]

I have no interest in sailing backwards (into a headwind and opposite to the current flow), to get to SA, from which you folk are desperately trying to escape.... So I repeat, build your boats and get a move on... Adventure awaits... Your escape route is planned and not to much of a challenge...

http://www.abc.net.au/news/stories/2...section=justin "More asylum seekers arrive off WA coast" - Nup, does not look like a 'saffa boat'? "guantanimo" - err Christmas Island -10.4917 deg S latitude 105.6496 deg E longitude is Australian territory... and a tropical Island resort for illegal (boat-people) immigrants...

"School's Out" is a 44C stretched and heavier finish? - I am lighter and smaller 39C with mini-keels that add to buoyancy (and a bit of weight / drag) and expect 6+knots calm seas no wind on 1500 watts each, and around displacement speed with the full burst of twin 4000 watt motors giving 97kg static thrust equivalent...

...

I can't see you getting 6 knots plus from the Torqeedo's at 1500 Watts each. IIRC School's Out was good for about 4 knots at that.

And by the time you have the genset, the 48 volt battery system, as well as a 12 volt battery system, plus the solar panels, and all the 35mm cabling, your boat isn't going to be a light 39C.

The noise of them wasn't so bad as it may have seemed in the video, - they were certainly quieter than outboard powered cats I've been on.

When Bryan called out "7.6 knots" IIRC we were getting a bit of help from both wind and tide. Also the dinghy was off the boat, (doing the filming) which would possibly have made more difference than you'd expect - it's a fair bit heavier than me, and I'm 115 kg.

I've powered my 44C with a pair of Honda 20 "Powerthrust" motors, as used on "Out Of The Bag" . That boat seemed to perform pretty well, I think best speed under both motors was 11 knots, one motor was 9.

Like everything, the Honda's have their pro's and cons, the props aren't as big as Yamaha 25 HT's, and the gear ratios aren't as good, but then the Hondas are 30% lighter, have a longer leg and a bigger alternator. Plus I got one near-new (20 hours) at half price.

If I was starting from scratch, I think I'd look into fitting a Yamaha 60 HT on one hull, and a Yam 9.9HT on the other. Put the batteries in the 9.9's hull to balance things out.

IMO the Yam 25 HT's are way too heavy at 92 kg each, (Honda 20s are 65kg) the 9.9's are 53kg, 40's are Ok at 100kg, (BUT AFAIK there isn't a high thrust version of the 40) and the 60HT is 116kg. .

So A 60HT plus a 9.9HT would weigh 170kg, less than either a pair of 25's or 40's and I think a 60HT would really get things moving. It's injected so possibly more economical (at the same speeds) compared to the 25.

The downside is the 60 is physically bloody big.

I concur about motors - the Yammie 25 is a friendly brute. Our old Honda 25 was a lovely bit of kit up top. Nice three cylinder job, triple carby - at idle it was very quiet. Only had one or two revs that it would shake a bit.

Then some scumbag stole it and my retractable nacelle and I couldn't replace it. So I got a Yammie 25. It is heavier and throatier - balls and muscle whereas the Honda was a smooth operator. The Yammie is much shorter because the mount is so long. Measure from the mount bottom to the bottom of the leg - a better way to measure for cat sailors.

The big diff was in the prop. The Honda had a 9 inch prop. Pi r squared is 4.5 x 4.5 x 3.14 = 63 square inches. The Yammie has a 12 inch prop = 113 square inches.

When we used to get hit by a gust with the Honda Kankama would slow appreciably. With the Yammie she has almost twice the grip on the water. This is one reason why I am dubious about calm speed runs.

The Yammie has another benefit - it can reverse. When we first put it on my wife and I had trouble anchoring. We looked at each other - What the heck? We had anchored up and down the coast on this very boat with the same chain and anchor and technique. In the end Deb said - "Maybe it is the motor"
She was right.

We were giving the motor the same amount of throttle as the Honda and the anchor was being flung across the bottom. We had to back off quite a bit.

If I could I would get the guys at Honda to steal the leg from the Yammie - or visa versa. I like the idea of the 60 and 9.9 too.

Oh seems Claude may be disappointed - time will tell... that is for after Xmas decisions... The Torqeedo 4.0 R screw is 12" x 10" optimised for forward thrust of 214 lbs (I calculate that at about 97kg?) with this statement "Torqeedo static thrust measurement is based on globally valid ISO standards. Static thrust figures for conventional trolling motors are measured digressively, which results in higher values. In order to compare Torqeedo static thrusts data with conventional trolling motors, add approximately 50% to the Torqeedo static thrust values."...
The first couple of images are of the centre walkway and whatever out to the forward beam... next shows the chamfer panel between hull and bridgedeck, above the waterline and adds significant internal space and reserve buoyancy... and some panels epoxied together to become the aft chainplates - - I guess/think? The last being a general view forward...

The discussion on outboards is very good and gives plenty food for thought.

Are the dream team camera shy?

That is in the ROARING 40'S - - Fuckin cold and 40knots PLUS and absolutely HUGE seas..... I would rather the warmer climes whilst there is a good window of SE trades for a broad reach in relatively modest winds and heading for warmer climes... Scheduled to arrive here (Brisbane in early/mid April, just after "cyclone season" and be happily moored in the Caboolture River, attend the launch festivities, then work our way up north before the summer cyclones to Cairns around November thence to the Louisades...

Mas, I used to be a Yamaha fan, but not any more. The CDI on my motor packed up. I stripped the CDI by taking the rubber sealant filler out. There are lots of dry joints on the PCB ! The components were stuck in the board and some was never soldered. Since it worked, the not soldered contacts deteriorated and the CDI malfunctioned. VERY POOR WORKMANSHIP. A new CDI is going to cost what I can pay for the same motor with a CDI in it

So, if I was you I'd look at the other options instead, those motors that Wynabd is selling is a far better option imo. I have also heard some good things from other owners and at a better price.

Your escape route is planned and not to much of a challenge...

I wasn't planning it the short way there

You sail to the US first... tell them SURPRISE ! I'm here you bunch of ugly Ausies !
They will say this is not Australia...
Oh ?
Yeah this is the US...
Then which way is Australia ?
That way ! (pointing)
But that's the direction I was going, how come I ended up in the US ?
Where are you from ?
Safrica
Well then you should have headed that way (Pointing again the other direction)
But you just said it's that way (point the first firection)
If you were going from Safrica you should have headed that way in the first place.
Ok, must I go back that way via Safrica or is it shorter the way you pointed ?
Can I have some water please. I have been dringing sea water for the last four days
(Take the whiskey and glasses out)

Sounds a little more realistic Mas.


Are those chainplates just laminated Duflex ? Is the gap between the laminations where you slip them onto the hull skin ? They look really thick and very rigid.
I like the way you can now " weld " components together ( like the catwalk to the forward beam ) with modern composite laminations .Everything will look so smooth and faired together.Will look classy Mas !!!!

We are running guided tours for the discounted price of 1 oz of gold per person, including a 3 course meal (grilled barramundi, potato or wood chips, maybe some lettuce and other vegetables/salad & tomato sauce - washed down with a stubby of genuine Bundaberg ginger beer - non alcoholic...) - for those that like harder stuff, some time in a local jail is an additional cost optional item...

Chainplates? what? who? were? - - Oh those, well you will have to wait and see (I don't know yet either....)

Further good news, the genset will be on its way from near Cessnock, NSW to the boat build site, 40km north of Brisbane, on Tuesday 6 Oct to arrive a day or so later... A compact 722cc Kubota engine with dual Delco alternators to charge a 48V bank of batteries for less than Au$10,000.00 including regulator and separate 48 to 12 volt charger for nav stuff, leaving the 12 engine start alone... Suppliers were http://seawasp.com.au/products/nanni.html and http://www.wattagan.com.au/index.htm...tml&lang=en-us - both did a special version to specifically meet my needs...

Hey hey its friday afternoon this side of the globe and i just heard the town crier go by ringing his bell "Al's well - al's well" close up shop 15h00 and go build a boat

Must say the camera shy dream team did a sterling job this week and some more points to them

just a little something to cheer you up in view of the gold prices and that and that
