Greetings, I'm Mikel / Modeleer: hailing ship to ship from Portland, Oregon.
I'm one of the founding members of the
original Vulcania Volunteers
& I also host a Goff/Nautilus enthusiast / study group on facebook.
facebook title: NAUTILUS by GOFF / 20,000 Leagues Under the Sea {1954}
(I too am a member of NautilusSubmarine)A good-friend, colleague & licensed Disney artist :
David McCamant spent 4 yrs creating the difinitive Goff/Nautilus Plans in 2008.

Harper Goff's Nautilus is 200 ft long according to the Disney Archives


So... a Goff/Nautilus model 115.5 inches long = approx. 1/21st scale.
And a "1/32 Scale Capt Nemos Nautilus" measures in at 75 inches long.
The
66.5" Customs Replicas Nautilus model is closer to
1/35th scale than 1/32nd scale
(hi Tommie!)For those of you interested in scale realism applied to the Goff/Nautilus,
I'm providing a comprehensive list of the Goff/Nautilus in various popular modeling scales:
