Sorry about your timber list prob. You are having trouble with "professionals"
The plan doesn't need to be converted, but the timber list probably does. In fact DO NOT CONVERT ANY OF THE BUILDING MEASUREMENTS!!!! Build entirely in imperial (you have a good grasp of that! and don't convert to metric or dogbums! Because everything will be a bit out and the effect can be quite big.
But for ordering materials you will have to convert. It won't take long ... maybe an hour.
Multiply any lengths in feet by 0.3 to get the number of metres.
For cross sections of timber .. common sizes are
3/4" = 19mm
1 1/2" = 37mm
1 3/4" = 45mm
3" = 75mm
Anything else you will have to convert knowing that inches are 25mm and quarter inches are 6mm. Or if you get a tape measure with one edge in metric and the other in imperial you can see the direct conversion yourself.
Timber must be Kiln dried (you won't get air dried stock anywhere in the known practical universe)
Tell the timberyard guys that the sizing just has to be close to what you need (within 3mm) and you want the order filled as much as possible from standard sizes, but anything special you will pay for it to be machined down. Ask them to tell you which pieces they have to machine down specially.
Best wishes
Michael.

Builder plate
Just be aware, if you decide to guess the information required on the plate and it is not correct or compliant with the rules and there is an serious accident or death, there is a compulsory goverment investigation of the incident. If your boat is found inadequate and the information is found to be incorrect, there are serious consequences for you the builder. This was brought up at the last Naval Architect conference last year in Brisbane, where the Australian Maritime Safety Authority was present and questioned in this regard.

Wood
So update on the wood
I sent an email to llazaridestimberagencies.com
These guys are very helpful he did a rough count and gave a price around the 1100-1200 for everything Australia grown
Now i was expecting 2500 and was planning to put things on hold till money came around (just like everyone else i would image) so at this point things are looking very good
Ill order my wood this week and its going to be all balls rolling next week sometime if all goes to plan

Absolutely Mark!
And if the boat is not properly sorted and that type of negligence was the responsibility of the builder then the plate doesn't change anything. The builder is liable with or without the plate.

panic panic
Its ok don't panic don't panic
i understand you guys when you talking about safety there is no shortcut to quality
and thats what its all about when you do it yourself
I have seen a couple of Glen-l boats for sale on ebay over the last few months and they all had rego numbers on them
There is one in there today
http://cgi.ebay.com.au/ws/eBayISAPI....:X:RTQ:AU:1123
I would imagine its not all that hard if the boat looks up to scratch
I have the plans and weight and all the other details that would normally be on the plate
so what could be so hard
Now if you want to talk HARD try getting V8 lc torana through an engineers report
Sheeez talk about Rectal probes
So in short they have been building wooden boats since the beginning of time its not brain surgery its just the red tape that makes it tricky
And thanks for the input every little bit helps and is appreciated

Howdy Steve,
Main thing ... is to do the research before you close the deck or cockpit over and see how much buoyancy you will need - or IF you will need it. Everything else on the plate is trivial.
The buoyancy calculation is not too hard for the basic level of flotation and Mark or I can help you add up the weights ... it is a back of an envelope type calculation so won't cost anything.

Abp
So i have sent some emails about an ABP
Doesn't seem to hard
Here is what i get back from
AUSTRALIAN MARINE INDUSTRIES FEDERATION
Please call Max or Rob at Metal Signs and Labels on xxxxxxxx and they will be able to sell you a one off blank ABP for $30 including GST and postage. You will then need to get the information engraved on to the plate.
""You will need to get a naval architect to verify the information."""
I didn't post there phone number for obvious reasons
So how much does that cost and where can i get it done
Did someone mention they were a Naval architect???????????????????????

If Michael checks off the specifications as correct and isn't able to legally sign off on the plate, mail it to me and I'll sign off on it, though I suspect there's a local NA that's available for this service.

Par,
No, you must be an Australian. I tried to explain all this before, but with the response, decided to let it go. Well, as Steve is finding out, it's not trivial and its law.
Basically here is how it works.
The information provided must be calculated by using either ABYC, Australian Standards, ISO xxx, etc..There are a number of them.
The person calculating the info, it's their name which goes on the plate. Not the builder. The person providing the info must be qualified by formal education either:
1/ a Nav Arch
2/ Marine Engineer
3/ Marine Surveyor
4/ Shipwright
Now a person who's been working in the industry for around 15 -20 years, can also provide the information however, they must be able to PROVE, if the need arises, that they are in a position of competency. Boat building laborers etc do not apply.
The information calculated, must be kept on record for the lifetime of the vessel or, the compotent persons working lifetime. This means that if the boat is built, then resold a number of times over the years, the competent person are still responsible for that info. If however, during these resold events, the boat is altered in such a way as to make the information redundant, then the compotent person is no longer responsible but, now the new owner. In South Australia for example, for not having the correct info on the plate equates to a $5000 fine.
The info on the plate regarding the competent person must also include not only his/ her name, but also their level of competency.
Making your own plate or using stickers is illegal and you will be fined. You have to use the blank builder's plate and etch in the info required. Without a builders plate, selling the boat can also result in a fine.
In regards to Steve-35, Glen-L-Designs cannot be the competent person. He's an American! If say for example Glen-L provided Steve_35 with the info and Steve put it on, knowing its correct and then wrote is own name, Steve is in the ???? because he is not a competent person.
These matters, do not just concern you being involved in an accident where you're at fault causing grievous bodily harm. In the same way as if you're driving down the road in your car and someone rear-end you. Under the law, they're at fault and they pay the damages. If no one is hurt, insurance details are exchanged and you go on. However, if someone is hurt, the Police must be called in. Not your fault, but the police check out your license and rego anyway and away you go.
The same applies here. However, if the info provided on the plate is false, you're in trouble. If the info provided on the plate is supplied by someone else who is not competent and an accident occurs 15 years later, with the boat having been resold a number of times, that "competent" person is in trouble.
Overall, this is not Trivial, its very serious ???? happening here and those numbers had better be correct and the person providing those numbers had better be "competent".
This is why I made the comment about purchasing power boat plans from overseas and the problems you will encounter. In other words, finding someone who is willing to accept responsibility for your boat - for its entire life, or theirs. Hmm ..Interesting isn't it. The same also applies to purchasing plans from say "Build-a-boat"
Working at Tom Fexas Yacht Designs (USA) in the 55ft - 200ft luxury power boat market, all the designs had to conform to ABYC standards. Although, not mandatory by government like our builders plate, the insurance companies demanded it or the boats not covered. Simple. Here in oz though, not only are the insurance companies demand it, but so is the government.
That is why all our powerboat designs are ABYC compliant and, also builder's plate compliant, and it's my name that goes on the plate.
Hope this clears a few things

hohohoho
You guys are right but for me thats way to much info
All i need to know is
Buy the plate
Have someone check the Design against the info supplied (In Australia)
Engrave the plate
Stick it on
Get a HIN
Pay the reg
Thats about it according to the NSW Maritime and Australian Marine industrys Federation
As the woman from NSW Maritime said we try to make it as easy as possible
For the people that need to know this info thats great but for the average joe blow its too much all it will do is put people off when its not hard at all
I do appreciate all of the time and effort
But you aint putting me off thats for sure

So, although I have three engineering degrees, the last in naval architecture and over 70 designs to my credit, across 30+ years of effort, my work couldn't be certified by me to conform to acceptable standards (ABYC, etc.) in Australia?
Seems to be a rather limiting policy to say the least.

Par,
I agree, It's all about accountablility and their access to you. Living outside of the country makes it hard to make you accountable. Personally, I find the whole thing a joke and a pain in the *&%^#. No doubt, some idiot trying to justify his job came up with this idea
Simon. Yes a bit lenghy in response, but just thought I'd throw it it just to give you an idea of the goings on behind the scenes and what they can do.
Look for someone in your area. They'll need to look over the boat, take a few measurements etc. I went through all this with our own boat and typically, the girl behind the counter was a waste of time. I ended up ring the qld maritime crowd and got in touch with the safety oficer who gave the real run down and the ramifications of it all. Also, you don't need a HIN as this only applies to production boatbuilders.

rules is rules
I have been watching this thread with great interest as I begin soon on my hartley (soon is a relative term), it all seems pretty simple really, I had more dramas getting modified vehicles engineered and signed off and when you think about it we all like to have our friends out in the boat and god forbid if something went wrong it's all about accountability (and govy taxes), soooo get it checked over, fill in the plate, get the rego and get wet having fun
