Title: Viper 640 Line Drawings
Post by: Jon Stubbs on September 22, 2012, 07:16:01 AM
With a good fleet in Western Australia and a container of Viper 640's arriving in Sydney, we thought it might soon be time to look at state and national titles in Australia.

After visiting an interesting shop in Boston that had heaps of ship models, we thought a half model of a Viper 640, mounted on a wood,  might be a good trophy.

My father is a talented ship model maker. All he requires are line drawings of the Viper.

I know a little bit of the history of the Viper 640 and previously, line drawings sounded like a tall order.
Recently the class did laser plotting of the Viper 640 to  develop 2-D and 3-D drawings and data files that precisely define the boat. Are there now a set of line drawings available?

Any suggestions welcome.

Dave Nickerson has the hull and keel lines from the scans.
Dave at Nickersons dot org

The line drawings on the trophy that Rod brought home should give you the rig.

Does this have the modern keel bulb and stern scoop?

This is just something I did in Adobe Illustrator. It is not the quality of the laser scan. It has your crooked rudder on it Justin :-D

Thats a lines plan not a drawing. Also that needs updating as the sail plan looks nothing like that.

Thanks for volunteering Matt ;-)

It should be easy to get line drawings from the scans of the boat. Kind of scary no originals exist.

Justin, o governor of ours, can you get the TC to publish a line drawing for us?

Should we ask, Ben?, Dave N?, Timbo?

Maybe line drawings is not the right term.
What my dad needs to make a half model for a trophy is not just an outline,  but plans to make the hull shape correct and to scale.
I assume it would be something like the attached plans for a lightning 18 I found on the net.

Have asked Jim Taylor to get me a price on developing a drawing like what Jon attached from the zillions of data points we have from the hull/deck/foil scanning project.  See as a good possible use of class funds.  More later.

Would have thought a set of plans would have been automatically produced from the data points.

I think we ended up with a 3d model that sections can be pulled from but the cash dried up for getting lines and sections drawn in 2d. Could be wrong though.

With a full 3D model you should be able to pull a set of lines from it for minimal money.

O Governor has not been his usual chipper self. I have been quite unwell but I have computer on my lap today.

The zillions of data points have fixed the shape of the Viper for posterity so if, gawd forbid, something happened to the plug and the molds,  the Class (aka Dave Nickerson) has the shape on a CD and a new plug could be CNCd to produce exactly the same boat.

Dave and his band of merry engineers also overlaid a scan of a pre-Rondar boat and a latest Rondar boat to check the shape had stayed consistent within 100ths of mm.

I beleive that the Tech committee and Zimmer were standing in the room while the scan was happening, so theoretcially we could make a half model of them as well. Jeff has expressed interest in an inflateable version of Timbo!
