My little piece of peace

Great progress Mas, I'm quite green with envy.

Sad about the ticket, but I'm sure it was about safety and nothing to do with revenue raising...that's weird, my nose seems to be getting longer...

Did you research induction cooktops at all?
I've been wondering if they're worthwhile. They are certainly more efficient, if somewhat more expensive to buy.

 

Hi Autodafe, Yes toooo expensive (speeding fine & induction cooktop) and who can complain about (ceramic cooktop @) $50.00 for the one I got!...

The second hull has all the panels in place, now glue & strip glass the joins inside, add the bulkheads, then turn it upside down and glue and seam the outside, bog and fair then join the two halves - well the big steps - and it really is coming along fast.... Things will really seem to slow down when 'fit-out' is the menu

 

SMG Multihulls electric drive Cat

Mas,

I presume you have tracked down this website of SMG Multihull with 50ft capable of up tp 10 knots with FisherPanda wisper electric drives. Links at bottom.

from website ................The ultimate catamaran


Gerhard Schein gives his best and works in his mastermind office in Thalheim day and night on the ultimate catamaran.


”SMG 50plus”. The 50 means feet, that means some more than 15 meters length! And the plus points at the many innovations, included in this catamaran. For example the SMG 50 is the first catamaran sporting an A-frame-rig! The advantages are speaking for themselves – the mast with a height of 18 meters does not need any supporting rigging to the side where the forces are greatest – it stands for itself. Furthermore it is possible to set and reef the sails with a minimum of buss at any point of sail. The catamaran doesn’t have keels or duggerboards. But the use of deep V-underbodies like sport catamarans and former Polynesian craft gives very good pointing ability.


The advantage is obvious. 85 cm of draft with 15 m of length is record-breaking and opens the most beautiful bays. It’s also possible to beach this catamaran very easily.



The whisper-engine concept



There is also an innovation with the propulsion system. A high-voltage electro motor does its job in each hull. The power is provided by whisper generator. Actually the Luxusliner “Queen Mary II” is powered dieseleletric. The North German Company FISCHER PANDA (www.fischerpanda.de) provides the innovative propulsion – you have to concentrate to hear the motor at all – all this comes along with around 40 % of fuel saving and the advantage of the amenities of 220 AC on board - providing again more freedom.



Construction in a high quality



The first prototype with its first launching in autumn 2005 was built from a Bulgarian boatbuilding group in Varna.


The start shoot was at june 2003. The SMG Multihull GmbH was founded and Michael Traussnig (www.yacht-foto.com) visualized the plans in 3 D. At that time it started!


Until July 2006 we are building the SMG 50plus in Cape Town in a high professionally way and founded the SMG Multihull South Africa at the beginning of 2007.

Great progress, seems to me you spent considerable time in preparing for the build.
Any advise for those of us that are still in that planning (dreaming) phase?

 

For me the FischerPanda gensets were prohibitively expensive and rating seemed to be "peak" and described as "continuous" prices offered last week were: - AGT-DDC PMS 8000-48v - $27,424.40 + GST, - - AGT-DDC PMS 10000-48v - $29,563.00 + GST, - - AGT-DDC PMS 11000-48v - $31,927.00 + GST... Gst here is 10% Prices in AU$ at recent exchange rates for EU..... - - - and still using a Kubota 3 cyl powerplant, I halved the price and less than half the weight as FP will not deliver without the "soundproof" box...??? I am using a pair of DELCO 20 pole brushless alternators connected in series...

Wow 8.5 tons EMPTY? mine fully loaded in cruising mode is about 4500kg, if that 50ft boat becomes filled up as in the illustrations should add another 1500 to 2500kg... Plus fuel & water...

I spent near 2 years looking at my needs (not aspirations) and found the Bob Oram design philosophy met nearly all my needs - The thing is to carefully consider where one intends to cruise, and what one NEEDS rather than what one desires to pose in/on... Figure out whether you intend to be a marina resident or be as independent as possible, are you cruising (live-aboard abroad) or day-sail racing around the buoys? - - when the weather blows up will you run to a marina of seek to hide up a nearby creek, or, head for mid ocean? - - - - All logical and sensible steps in the process which will determine the direction of the compromises made in selecting the design of the boat for you...

 

Mas,

I only mentioned the SMG link because of the FP electric drives and clearly you have done plenty of research. I priced a 6000i generator at Sancuary Cove and concur they are premium price.

Have spent a couple of cyclones in mangroves (one in Percy Is on a 50ft Crowther motor cat - Ruby) waiting to pass and agree mangroves are the only place to be not in a marina if **** happens.

I reckon I have about another 12-18 months of research to do but am looking at around 44-45ft and there a number of good aussie designs to observe including the Oram44.

 

May I suggest you look at Peter Brady designs, he has some very practical and exclusive features in his boats.

 

Landlubber, Did he have an involvement with a powercat build at the end of Aquarium in Hemmant? - or was his the scimitar 1010? - which is a very nice platform for fishing locally...

I was down that way yesterday to buy a bobtail nanni/Kubota N3.21 from Sea Wasp Australia http://seawasp.com.au/products/nanni.html .... delivery in 3 weeks and a fair price.... I will have a pair of Delco 100A alternators and controllers sorted out by Phil Dorman, Wattagan Innovations, http://www.wattagan.com.au/index.html?target=p_8.html&lang=en-us also at a quite reasonable price.....

downunder, don't worry about my curt sounding response - mostly preoccupied with other things/projects - I am really quite nice, and prepared to talk the ears off an elephant... - and in text mode tend towards brevity in extreemis...?

Today's progress, - This is how I like to see a "highway Patrol car" thence to progress on the second hull... with the first one pushed aside to make room, waiting for the both hulls to be faired, sanded then undercoated ready for turning right side up , joining and fitting out???

 

Sure, from the shoulders on downwards

 

Fanie, That line will not work with me

 

One has to try tho

I'm sure you're one hell of a social treat. he eh... just a pity you don't fish, could have gotten you so close to perfect

Darn boats go slow eh. I deliberately stay away for a couple of days hoping to see some major progress, but no.
Instead the stuff just gets moved around in the shed

I have to do my beams next, jig made. Thinking of some simple automation to make the work easier and faster.

Keep moving the stuff around. It looks like progress.

 

Well, no new pictures today as the work is not really visual... finishing the bow, internal and externals as well as geting ready to place the bulkheads needed for "roll-over" so the bum can be finished, another 4kg of copper dust to go on as part of the anti-fouling process. - All should be completed in 2 weeks and then ready for the joining of the 2 sections to make a cat!

So yew lot, aveagoodweekendanddontforgettheaerogard (aerogard is a spray-on insect repellent)

Fanie, I do fish, but only for food, loose interest too quickly to play games.... then I go and start drinking, and when I piss over the side, a fish will then commit suicide and go for the hook (nothing like a threat to get a response)...

 

Is this boat to use water ballast? How will that work? Can you give me a url on the rig you are planing I searched around this site, but never found anything other than more claims of what a good rig it was with no information. There are hundreds of potential pages that come up in a search, and X-IT did not come up at all. I think Bob has the best process for doing the big builds. Basically just scaled up stitch and glue, which everyone likes, but runs out of steam with plywood in fairly small sizes.

 

ThomD, the build is a little like S&G, but it aint, it works with balsa-cored-glass stuff (DuFLEX), it is bloody good when the appropriate techniques are used - No water ballast - why slow it down with extra weight? - It is not a mono that needs tons of ballast to keep upright, just good design from the start...

The Hitch-hiker rig was developed by John Hitch, (some images here http://www.boatdesign.net/forums/multihulls/main-less-rig-21274-5.html#post195286 post #73 and http://www.boatdesign.net/forums/multihulls/main-less-rig-21274-2.html post 21) - an Australian designer and builder, with a knack for some pretty amazing engineering stuff - "Wired" is another of his designs.... (use the search engine to search inside 'boatdesign' and you will find quite a few images) Basically the rig is for "downhill" sailing but can point fairly high when push comes to shove, once the constraints are understood (I do not yet - so don't ask me) and uses 2 genoa like sails one to each bow of a cat - never sail wing-on-wing as there is no advantage there. - No mainsail and mine will have a forward cockpit for sail work (not often) and which does not get wet very often - but most driving is on autopilot (wander almost anywhere using hand control on manual as a "remote wheel" - legal for racing - ) - or inside sipping coffee or....

4 of Bob Oram's design kits from ATL will fit inside a 40ft container, so with a group getting together stuff for the hulls can be purchased for either the 39 or 44 ft versions - check with Bob first.... For mine, all the panels came on one pallet of 1100kg a bit over 8 x 4 x 4.5ft and the other stuff 800kg? or so on another pallet... The difficult part outside Australia is the hire of the Z-press needed in gluing the specially prepared (patterns cut with router & other cutters by a computer controlled system) panels together in sequence to produce the pre-cut 40ft long sections to make the hulls, bulkheads & etc....

 

Thanks M. I understood that bob's 39 footer, Mango, used water ballast so I thought you might be in the same boat. I see that yours is 2 feet wider though. I will check out those rigs, thanks.
