Let's try again: My previous post about it was a bit disconcerting in the title - Skipper got an EPIRB... - my fault.
I use to write with less drama and more fun.
Anyway, the topic is about a Great sailing boat class design and the attempts to re- create, -invent, -interpretate it.
I must admitt with a sense of frustration, that the task is difficult, the sheer abundance of 3D curves swelling up, down and sideways of that mighty boat's hull is unnerving.
Compared to a contemporary design of a VOR racer, it's like a snakeprint V/S an armchair...

As you can see I'm keeping on but, please, Any suggestion and/or useful tip from someone who as tried the same task yet
( I refuse even to think, nobody had... ) will be very helpful; best tips could be how to evaluate - remaining in DS - the progresses on small hull refinements and the leaned hull attitude.
Again, many thanks.
Jurgen.

Underwater lines in profile, similar to British design of 1934, the approach to keel lines is more radical than contemporary designs.
I try to reduce drag leaving round lines at the beam.
Any comment and/or suggestion warmly welcomed.
Cheers, Jurgen.

Can I please ask where you got the line drawings from for the J-Class's, I have been looking for a reasonable sized jpeg just for this reason but not had much hope, I ordered a set from Cormwall Model Boats, but this came as an A0 Sheet, and I have tried with little success to scan the drawing and stitch them together, but it is not working!

Great work by the way

James

PS. I have sailed on Valsheda 3 times now.

Hi James and Jurgen,

My approach to this is labourious but works. Take measurements with a ruler and transfer the body plan into cad.. From there it is a fairly easy process to create a bmp/jpg. The attachement was done from an AO and an A3 blueprint.

Hope this helps.

Best Regards
Bob

From the official J class site you can purchase them and carefully searching the web there are fragments of The Book itself.
Thank you but looking carefully it's a mess...
YOU LUCKY XXXXXXX !!! You mean ON BOARD... Envy, envy, envy...
An angry salute, Jurgen.

Thanks for that Maryak, much appreciated, though the hull design is a lot different to that I know, but it will be a good starting point to see if I can create a hull from.

Thanks for the good find...

James

A batch of images of pre-war boats: plans are easy to export as background.
I want a pic of you shinin' the brass on Velsheda!
Bye, Jurgen.
