Hi

You are quite right ,but please remember that the skills of the builder
can also compensate for bad plans. Now I have no experience with the
plans you discuss, but I know about a very famous shipyard who bought a
serie of very expensive plans for serie of steel boats -- these plans
was so bad even the boats displayed very nice, but the making of the
plans simply produced ribs for boats that could not be build, hull
surfaces that would not meet the frames and after more than halve a
year just trying to build one of the designs the shipyard was nearly
broke.
I say so from knowing a very skilled metal worker working with this
project --- he figured out what was wrong and scrapped all the lofted
frames and took the measures from the sheets and just the few frames
that acturly followed the lines in the plans. The space between the
projected ribs in the plans and the panels turned out to be up to 12
Cm. apart, ------- now one boat was finaly made and please bear in mind
that this shipyard was among the top profesional ones ,but the plans
was scrapped money thrown out of the window , and what's more to say ;
sure one boat was build but it was oly possible becaurse a few very
skilled craftsmen could make it work and not from the plans but from
experience and hands-on experience, still if you measured the ship
produced up against the plans you would say it was not the same ship.

Eh --- please let me add, that the worse foult with those plans you
could acturly see right away in the plans ; it was two or 3 chine hulls
and not one single frame showed the curve that a singe curved paneling
_will_ show when sliced seen from front.
No rib or very few ribs, will be strait in real with two or tree chine
hulls unless we talk about very clumpsy designs, but these ribs in
these very expensive plans all showed as strait lines in the front
view, ------ offcaurse the shipyard shuld have notised from the start,
but they belived in that when a world's famous designer made plans,
then they would work.

Well, the designer should have been sued, because it is his/her
responsibility to ensure the measurements and lofting, etc. will mate
together to a specified tolerance in the real world.

If not, all that steel is just an abstract sculpture. CAD can and has
done this sort of thing for decades now...there is no excuse and the
yard has a strong case for putting the designer out of business,
unless a third party fabricated the steel improperly, perhaps.
