We both hung off one, and at 200kg that is OK by me... Some high tensile stuff.... and maybe I got some numbers wrong (not the first time)

That's 30 knots. http://alluramarine.com.au/

I don't have a web site.

Did you watch the video in the link I posted? It shows the boat doing 30 knots.

Ok I just looked at your link. Your specifications page says that you do 20kts using 400HP of the available 750HP using 80 liters an hour.

I am 44 feet, 14 tons and at 20kts I use 40 liters an hour I have no idea how much Hp I am using from the available 500HP but rpm is approx 3500 from max 4200 and the turbo boost meters are on zero. Speed is GPS.

I think allura is catering to the penile-challenged over capitalised? - - - Heck, I think the Brisbane "City Cats" have better performance & fuel economy than that, but they do not make waves do not roar so noisily and work only in the shelter of the Brisbane River from Queensland University campus down to the Hamilton Reach... I think blared has a picture in his library....

Honestly, it's really not my website.

And to prove it, I actually thought you were talking about 20 knots being the top speed. I haven't even looked at the specifications.

BTW 40 litres per hour for a 44' 14 tonne boat at 20 knots is truly amazingly good consumption.

Not all that magnificent, but Frosty's boat is Australian, I have seen a couple that will do with less than 30l/h at 20 knots... The original challenge by Robin Chamberlin, cruised "foriegn affair" from Brisbane to Hobart a bit slower and around 1.3 litres/nautical mile...

These fuel consumption figures make me dizzy

here in deepest darkest afrika i can get a budget flight from one end of the country to the other for the same amount that these guys spend on ONE HOURS fuel

he he - microcruisers rule man

Mas - looking good - go man go

the davits should have been bent and not welded
local muffler shops have nice pipe benders for car exhaust pipes

Geez Frosty, I think you're suffering from some avatar disorder. Now it looks like some eastern figure with two huge white tits over the shoulders which I assume represents heaven ??

Sorry Mas.

And here was innocent me thinking it was a sunset with Frosty's head hiding the sun?

Obviously you retards need pictures, and since I am a spiritual being and not debased by crass sexual references, herewith your photographic progress report - visually less 'in your face' with changes, but that is what happens when the internals/fit-out is being done...

They did extremely well to achieve 1.3 litres/mile then. Apparently they were targetting 1.8. Which was considered "a standard not attained in the current crop of pleasure power boats." ( http://www.sail-world.com/Australia/...=0&tickerCID=0 )

Which is why I felt that 2 litres/mile at 20 knots in a 14 tonne boat was pretty good going.

I do not think that Frosty knows the difference between litres, gallons and barrels when he is drinking, except to curse when they are empty...

A smaller one (in my gallery) could happily do better than 1 litre/mile at 15 knots & I was tempted to buy it but I wanted greater range - which meant 40 ft LOA and I ended up back sailing via the 39C I am building now

batteries, genset and solarpanels are on my mind at the present and to clarify the specs for them I need to settle on domestic power needs, ships nav & lights, computers and winches - anchor winch will be powered - (but the 2 genoa winches - electrify? - not really sure there....)
