nop they aren't
The Hull from the ghostship is way much smaller
How does your custom ghost ship have outboard chains for the shrouds? (including aft chains even though you don't have second pair of shrouds)? From what I can tell of stock photos, the Ghost Ship doesn't have those, and the shrouds/ratlines in fact just hang there, not fastened to anything, no deadeyes, no chains. Did you glue some on?
Or did you use a 3940 bottom hull? I'm so mind boggled!
