Ze:
I really like that Bruun design also. I'm not wild about the generous radius on the stem though. I like bows that cleave the water and don't push the water. Lapworth, Tripp Sr. and Chance did quite a few bows with big radii on the stems. It was easy to laminate but I think the designs of today show that it's not fast. When I see a boat moving along and shooting a big plume of water straight up the stem I think "wasted energy".

I agree totally about your wasted energy. so I got some sleepless night trying to avoid my flat 15 cm bow, if i can make it down to 5 cm radii it would be much better and still look like a traditional wooden boat bow.

Where exactly are you?

My plan was to build this boat with cheap labour in china (china is my second homecountry) but for different reason i had to move the whole project up to Norway, where  I found even cheaper labour. (myself)  :-)

When boat is finished it will sail back to middle kingdom (Yantai)

Building boats in your backyard in china is almost unheard of, so my reference is Norway. It was quite normal to make your own boat 30 years ago.  but along the way, people got lazy or rich (or both) and stopped doing this. I dont know anyone doing this in their backyard now. 

Its a little sad, cause young guys which is neither lazy or rich cant really find an environment where he/she can learn the tricks of trade and get a little push in the beginning. Boatbuilding is not that difficult, its mostly extremely timeconsuming. I spent hundreds of hours trying to figure out to read designers drawing and learn the lofting part. If I could have sat down and talk with a professional loftsman it would saved me lots of time.

Ive been reading S.S Rabl, Chapelle and a few other books about boatbuilding, and i must say, its not easy for an amateur to really grasp all that lofting stuff. When you can come to the real building part (in wood, metal or grp) its kind of easier. its mostly about problem solving and sleep on things which seems tricky

Ok...let me see if I get this straight..

You are a chinese guy who has figured out how to read design specs and loft, but moved to Norway because people like to build boats in their backyards out of aluminum using a wood design by yourself because you couldn't find cheap labor in China?

I got there by pure accident and fell in love with this strange country. its a little hate/love affair. China has endless possibilities but also endless problems for foreign devils.

I dont know if yachting will ever be popular in china but I really hope. They have a long coastline and my big dream is sailing  all the way from vladivostok and down to the vietnam border. But i havent even figured if its even possible due to red tape. 

There is this saying: Give chinese a sailboat, and you never see him again :-) Sofar i have seen maybe 1 or 2 sailboats. Even the sailing mecca Qingdao has hardly any boats. But among 1.3 billion chinese there must be a market someday. They really love everything western.

Ill try to fetch that south sea vagabonds. Never seen that one before.

The Ice Bird book I already have, thanks. I think Lewis also have few other good books.but i havent read them yet.

Btw. By last count, I found i have more than 300 sailing books stacked in boxes waiting for the boat to finish. Ive  probably just read less than 1/3. Rest is saved for long and boring nightwatches. Really look forward to read them all. Nothing is nicer than reading sailingbooks under a sparkling sky with wind from astern and boat is slowly moving across the sea.

not exactly sailboat, but at least building. im impressed with this guy with really modest financial resources he managed to build a oneman submarine out of steeldrums possible to dive to 10 meter. since there is no sea around BJ he is testing his project in a canal.

this is extremely lowcost project.

Had 2 guys and a girl helping the last 3 days, but unfortunately it is so cold outside (-29C) so we gave up working in the shed and went inside to do some rig-design instead. Working with metal in freezing cold is no fun. It easily rip the skin from our fingers.

Hi Zeyang,
No doubt about the French interest in & commitment to ld cruising.
There are a few questions though about the French national character & their enthusiasm for co-ops.

Tell us, les Anglophones, more about your co-op ideas.
What might be the financial, labour & social investments you are looking for?

Any special criteria in mind for potential applicants eg, humour (Monty Python, Mr. Bean, Steve Martin, Sacha Baron Cohen enthusiasts), politics (Mao, Chou En Lai, Sun Yat Sen, De Gaul, Churchill, Lenin bio readers), female pulchritude (Sophia Loren, Marilyn Monroe, Eva Gabor, Brigitte Bardot, appreciators), great writers (Dostoevsky, Cervantes, Conrad, readers), or age related criteria (no one who has ever heard of any of the fore mentioned persons vs ipod, mp3 users who cannot participate in a conversation & have never read a newspaper)?

just for the record. welding up the laps took me 83 hours. and probably more than 150 hours just for cleaning and brushing them. thankfully i got help during this stage else i will still been working on this. 

flipping is probably one more week. then its time to start welding the seams inside and swap those wood frames with alloy. then put in deckframes and start welding up the deck.

The term "great big brass ones" comes to mind, Zeyang... be careful. Is the shed strong enough to lower her down the other side, with come alongs from the top of the shed structure, or are you planning on jacks under the (now nearly horizontal) keel? Or both?
Just don't let anybody be brave and macho and foolish enough to get under her. If she decides to roll, being 20 years old and nearly invincible won't be enough to stop her. Slow, deliberate, and careful will win this battle... but it seems like that's the way you're appoaching it, so carry on.

[zeyang]

thanks, yes i try to take it very slowly and always have 2 backups. so if one breaks i will have a spare in case. 

chain hoist (2) from the roof then 4 poles underneath. im not sure about that roof. it was never constructed for lifting a boat, but sofar its still holding.

The cooling in the keel idea has been used by Brent Swain, the 'origami' steel boat designer & builder in BC.
Lots of additive to prevent rust & corrosion & I'm told it works well.
The weight is definitely an issue, but you get it midships & fairly low.
[/quote]


Yes, I have had no problems with the skeg cooled engine in my 36' steel Brent Swain, some other people with this system have had a little trouble getting the air lock out of the system but after that it's fair sailing (motoring actually). I use a 50:50 mix in my coolant no special additive to prevent corrosion other than what's in the antifreeze already. The dry exhaust is nice too just wrap it with 3+ layers of fibreglass exhaust tape and put a flexible coupler in close to the engine to absorb vibration from the engine carrying it's way along the exhaust pipe to the deck/hull. Of course with an aluminium housing for your coolant you may have to use the antifreeze designed for aluminium blocked engines rather than the standard antifreeze, worth looking into anyway.
A really interesting project with a lot of welding but I've always found aluminium welding a lot of fun since you get to move so damn fast. The swain hulls are kinda designed to limit the amount of welding needed on the hull so this is kinda opposite to that but very neat.
My boat's also spray foam insulated which is really nice, and with aluminium's lack of corrosion I would imagine it be even better used there. The foam gives the hull quite a surprising bit of stiffness too.

[Omer]

Zeyang, do you have any idea, how much the hull weighs at this stage, and with the frames proper installed. How will it compare to wood and fiberglass if you had built to equivalent scantlings.

[zeyang]

Zeyang, do you have any idea, how much the hull weighs at this stage, and with the frames proper installed. How will it compare to wood and fiberglass if you had built to equivalent scantlings.

i have used 10 plates, each of 280 kg.


then probably 100-150 kg of weld 

then frames is 200 kg

then deck is around 600 kg (?)

So maybe 3700 kg for bare hull. 

I think im a bit heavier than fibreglass and a bit lighter than wood, (im using 8 mm, with 2cm overlap, 1.6 cm in keel which is probably a bit stronger than what you will find in a massproduction alloy boat)

so i need more ballast to compensate for this, but thats ok. 




zeyang

[Omer]

In my opinion, you have a much stronger hull than what a production builder would be aiming for, using fiberglass or wood. Or in other words you would have a heavier hull using these materials for the same overall strength. Am i wright?
Which ever way you look at it, you have a heavy hull than what you would normally have. So why do you think you need more ballast. Do you think the original design is still heavier than what you have?

I really havent calculate the ballast i need - but i know the excact waterline from the original drawing, but the seatrail will tell me what is correct. 

The origial drawing is from 1907 and there is a rough sketch telling it should be around 2000 kg iron in the keel, which i find way too light than what i expect, compare to other 12 meter colin archers made with wood. 

But im not a professional. I learn as I go. Time will tell how much lead i need to stuff into the keel.




Some of these CA was quite heavy with inner skin also.. maybe that makes those boat quite heavy.. Problem with all these drawings, Archer never left a detailed description, only the drawings. rest was up to the shipwright at the yard.

One w3ay or another you are going to have to ballast the boat to get it down to it's designed sailing trim. If not the boat will be too tender.
I suspect you will end up with a ballast to displ ratio of around 36%, maybe 38%. That's a guess.

What is the designed displ?

Nice work Zeyang. I've peeked in one this from time to time when I'm not turning perfectly good wood into sawdust on Oh Joy. I really like the lapped look in aluminum.

Very cool.  You may want a bigger hook though when you go cruising?

Yes. I think so :-)

So does the lighter weight men you can have larger fuel & water tanks (filled mostly)..to help the ballast ?

both fuel and water can be used as ballast if i manage to make the tanks low in the boat.


engine is another good ballast also.

then ofcourse lead.

I have no good answer to displacement really. But maybe i can guess by look at others of approx same type. I think displ wouth be around 20 tonns, so i need to do some sea-trails to get a feeling.

ingrid (12.2 meter) had 1262 kg outside and 3000 kg inside

cape georg 36 feet: ballast: 4800 kg

bristol ch: (34 feet) 3000 kg ballast

CA-105: 10.33 meter Ballast: 2100 kg(?)

Direction:  10.05 meter.  3000 kg

Kurun. 10.05 meter: 1870 kg.

westsail 32. ballast: 3178 kg

LehgII 31.6 feet:  7700 pound.

What kind of bait do you use on that thing???

• This is my all time favorite thread. I respect your spirit and your individuality. I own two aluminum boats both out of 5086 one 42 ft ,one 44 ft. I have a sea chest in each and can highly recommend them, but for antifouling make them large enough to work inside. All so you have a great oppurtunity to install a false bottom in your keel to have both an efficent and trouble free keel cooling system without external fitments, great against the high lattitude growlers best of luck I cant wait for more

Ze:
If you post your general dimensions I think I can work out a reasonable displ.
Could you post the hull lines?
I can do it without if I have to.

Took me a few reads but I finally got what you said. Genius.

Your great Bob, it's folks like you that keep me coming back to SA cruisin. Good of you to offer to help Z out.

again,many thanks.

some more.its a little strange. from the drawing it specify 1580 kg. but i cant really believe it. I kind of think the boat will feel tender by only 1600 kg ballast when i compare to other boat of approx same size.  did the old master made a mistake?

The original design may have included a significant amount of internal ballast.

[Bob Perry]

Ze:
I estimate that on the DWL shown on your drawings the boat should weigh:
31,392 lbs.

I think by the time you get the boat finished you will need around 10,000 lbs. of total ballast.
Maybe as little as 8,100 lbs. But I can't imagine less than that.
Of course that depends a lot upon just how you outfit the boat bu I think a B/D of around 32% qill be about right.

PS
Right after I posted that I was down making a pot of tea when It ocurred to me that I had seen thsoe basic dimensions and shape before and not just in articles on CA.
Sure I had. Back when I was 15 years old Bill Garden gave me a book of his designs. I still have the book now 50 years later.
Garden's SEAL is very close in every way to what you are building.
The construction is timber with very heavy scantlings.
In typical Garden style he omits the displ. but his drawings do show 8,100 lbs. of ballast.

Then while I was typing this it occurred to me that the Garden SEAL design with a modified deck was built in Taiwan as the GLOBE 38.
I checked on YachtWorld and there is a Globve 38 for sale. They list the displ. as 30,000
Given they list 30,000 lbs. ( they always list low) I think my intitial estimate of 31,392 lbs. is going to be quite close for you.

I get 32,417 lbs...but Bob is pretty good at this stuff
