What a great thread - and a great boat! I'm green, blue, red and yellow with envy ;). I'm only sorry that I didn't catch up with it early last year - I've been so focussed on my own verbosity build mistakes that I haven't had my head above the bulwarks, so to speak, very much until recently (i.e., Lost in My Own Little World(TM)). I noticed the references to some fool who insists on tolerances of 0.01 mm - in wood, fer goodness' sake! What a dingbat. I'd steer clear of him, looks like a right nutter.
Pics of the Onka mouth made me homesick (again). <sigh> I miss Adelaide a lot.
Anyway, back to important things: lots of useful tips, especially with the hook-up wire in concert with your reply on the Eureka thread and to my PMs. Are you selling your plan(s)? I have been thinking that a single-seat kayak would be a useful supplement to the 2-person Eureka (and the 'Duck, and the Goat, and...).
Cheers,

Been having a long hard re-think about how I went about building this.
(I blame Alex for that. :D)
Several boats ago, I did briefly consider making up a 'traditional' kayak former
using a single beam through the middle of the moulds. Put in the too hard basket
- too much number-crunching figuring out where the beam should go. In any
case, I felt (correctly) that I didn't have the skill to cut the mounting holes
or the beam accurately enough. My poor addled brain found it easier to cope
with aligning 3 moulds on a ladder frame, then turning them over & doing the
aligning all over again at a later date.
OneOcean kayaks Kayak mold has a great tutorial
on building & aligning moulds on a central spine or beam. Using the tips &
tricks Vaclav Stejskal outlines, it is clear that 6 moulds can be set up for the
same effort as doing 3 twice, resulting in (hopefully) a fairer boat.
So I've revisited the design, faired up a couple of wobbles & squared up some
station points to allow moulds to be made for those points. Then worn the
numbers off the calculator figuring out where the spine/beam should fit. Just
about finished drawing the beam up & sanity checking the revised station
mould and panel measurements.
So... once the retaining wall is re-built, the paving relaid, the yard rehabilitated,
the pergola redesigned & rebuilt, & the chooks complete their PTSD counselling
from living through all the above, I guess I'll have to build another to test the
method & theory. :doh: or maybe :2tsup:
It is said that life is what happens while you are making other plans... :U
Building my 'real' sailing boat doesn't seem to be getting any closer. but on
the bright side, by the tiime I get to it, I might even have a shed to build it in.
:2tsup: :U

Sounds like a sensible resolution, you've learnt so much about what works and this can only add sophistication to your method and your understanding of the hull.
I admire your patience:2tsup:

A picture, as the saying goes, is worth a thousand words - a useful drawing that :).
