Hard chines from a drawing.

Chine !! what chine ?? it has a round tube !! sorry for giving you a hard time ! like a few others here cant resist it !! .

 

Edik, did you build your model with "lifts" taken from the waterlines or "sectioned" with station molds, then "plated" over battens?

Either method works and can be quite precise, though scale can be a greatly limiting factor. The problem then becomes, do you know the scale of the line drawing you're working with, as John has mentioned, scaling up or down can greatly affect the way the centers work out and if the hull will be well suited to your needs. In other words, if you've found a set of lines for a 6 m yacht, but attempt to make it a 12 m, you'll be in for a world of hurt, in many areas and aspects of the design, so it's very important to know the scale of the lines you're working with. A small scale change could be acceptable on normally proportioned craft, but much more then 15% and you'll run into huge issues.

Can you provide more information about the design, possibly post the lines drawing, so we can see what you're working with? Plus, what size do you think it is and at what size that you might want it to eventually be?

 

My post was a Parody about the impact event of a Shin on a Chine.
I cant count the boats I've owned and worked on since 1946. I've heard that word "Chine" all those years.
Nobody ever pointed to some part of a boat and said; "That's the Chine"

But my Shins have known intimately some parts of a lot of boats that could be referred to as a Chine.

 

I'm sure there have been other names for them as well. All part of the hard knocks of boatbuilidng. We apologize for all the edgy remarks but the temptation was too much to resist! This thread is beginning to sound like the script for a new movie, "The Chining" . . .

 

Yup, and throuot it all, nobody ever posted a photo of a Chine!

However I can post photos of some Dents in my Shin bones!

 

Ah! kumon, take it on the chine like a man!

 

A chine is any abrupt change in direction on a hull shell surface. My ex-wife has so much cellulite in her butt, she'd be considered a multi-chine, though the rest of her was pretty much round bilge . . .

 

You really believe she doesn't have a posting name here don't you?

 

I always thought that a chine had to be a 'crease' in the direction of travel.

So cellulite wouldn't qualify as a chine, it would be a manufacturing defect and should be remedied by the manufacturer, if the vessel is still under warranty.

If you have to repair it yourself, I recommend a light filler.

 

Ahh the witties! You guys can make anybody's evening a nice one.

 

Clearly you haven't seen my ex-wife's butt, which is decidedly multi-chine, though now that she's aging, maybe more lapstrake . . .

 

Hi,

thanks for posting. At this time I know the length, width, draft and displacement of the boat. I intend to keep the exactly the same size and not to make a 12m boat out of a 6m boat. So I thought I could create a larger grid that will allow 1:1 lofting and then transfer the lines - grid by grid. Because it's a hard chine boat the transfer of the lines should not be difficult (or so I think) because one only needs to points to draw a line.

 

I dunno , maybe - I met a gal once who had just left her NA husband, she said that if I had designs on her body, she would need a signed Statement of Requirements before she would sleep with me.

She wanted to know if I knew the difference between ForePlay and AftPlay ...

 

In the NE of US, there's a old wisdom saying. The only things of sufficient value to justify borrowing money to acquire are:" A sound bottom boat, a round bottom woman, and clear title land."
I ain't from the NE, I'm from extreme SE, but always admired the sentiment none-the-less.

 

Only the land will likely hold or increase its value, but in the long run the boat is the most fun. It depends how long you want to keep running. One guy I know who went this route for the woman way back, has been running for a long time - in the opposite direction . . .
