Very impressive, zeyang! She'll be very pretty on the water. Who drew the lines of your boat?

hi,
I traced it from an old drawing I found in a museum. the drawing was from 1906/1907 from a guy with name Colin Archer. (he must have been very old at that moment, cause his hand have been trembeling while putting down the lines)

The paper was stretched a little bit last 100 years but thankfully there was a scale-ruler on the paper, but i lofted it again and found out Im closer than 2 cm (1 inch) in full size. Thats pretty close. He never left any detailed description of the building process only lines for boat, rig and interior. I think he trusted his foremen/shipwrights or another boatyard that they have the experience to build without any detailed plan.

I will put up a picture of the old man on the bulkhead when i finish as a tribute to his drawing. I hope he will be happy with the shape of the hull.

It seems i cant upload picture. but you will find a picture of him on wikipedia.

Colin Archer

This looks great! That is a lot of work but I think Aluminum would be a great material when done correctly.
I recently put together a small model of our Ingrid 38 which was originally a Colin Archer design. I love our Ingrid 38 - just too bad it is a bit small for our big family

very nice. but i agree that 7 people will make ita little crampedl :-)
But ingrid should have been wider then you will have space enoug. I dont know why Atkins made it so narrow. It should have been some feet wider.

This boat looks like a pregnant whale :-)
4.30 meter wide.

What i plan to do if I end up in same situation as you, i will cut it in half, and extend by 3 meter . (49.99 feet) Ill put in an extra frame now to prepare for stretching in future.
Thats called growing a boat in old days.

Lol! It does sort of

That is an interesting idea about stretching the boat. I don't think I am energetic enough to try that though. That would take a LOT of forethought while building the boat! Your project looks great!

Easier to see this pregnant whale here.
basically beam is 1/3 or a little more of the length of the boat. By todays standard its quite beamy.

Not sure about the original tahiti.
but the steel version tahitiana was designed by weston farmer if i remember correctly. i think i have the drawings of that one somewhere in the boatshed.

work on last plank (sheerboard) today. a little tricky to give it a nice curve.

Hats off to you zeyang!

Working on re-inforcing the temporary frames to the hull by welding small alloy bits to the wood frame. When i flip the boat i will remove the wooden frame one by one, when i install the permanent alloy frame.

On outside i will make a square cradle in wood which will also be good to have to make the boat standing upright.

I am pretty sure that the Tahiti ketch was an Aitkin design. He also did a prettier one called the Carol ketch. I will check with a local friend who owned one. Checked with friend designer was John Hanna

Paul Erling Johnson's Venus design, of which most in varying sizes where built here in Bermuda, of Airex sandwich foam construction (I worked on a number of them), are closer to a Colin Archer (although you wont admit it, will you Paul )
I have sailed on both the Tahiti and the Venus designs, and other than both being double-enders, they have significantly different hull forms.
