The top pic, the basic lines layout was found on the web.
The others I've either taken from books and traced, or used the

Sounds Like you have found effective sources.


But I'm not intending to sell anything.
At least not at this stage.
Just trying to learn how to do the work.

Learning is always good,

Tracing sucks.
Terribly inaccurate since he lines look like they were drawn with a 3"
paint brush.

Makes fairing a lot harder than necessary.
And once faired, there is no telling how accurate the generated shape is
compared to the original.

Just so you know.... The final hull and foil shapes of a number of boats
out there don't always have a lot in common with the designed lines.
(That's what I often have to fix.)


How would you get the image of the frame stations or buttlines with
the cradle structures in the way?


My trailer has very little to interfere with the laser.
This CAD package used a splined curve.
Outta fill in the small gaps ok.

Prolly work, just watch out, computers can be real stupid sometimes.

At least it would be cheap and easy enough to try.

Actually, it sounds like it could just be a lot of fun.
If you could get about a box full of those line creating lasers and set
some up as waterplane, some as station and some as butts - you might be
able to reverse engineer a hull shape pretty effectively.

I'm interested to see how it works out.
