Orca Replica at Jaws 50 Event

I’ve seen some photos of the rebuilt Orca at the 50th event at Martha’s Vineyard and it looks amazing! I have a few Qs for anyone who was there and talked to the builder:

Is it a true 1:1 replica? The photos I’ve seen makes it look a bit smaller and stubbier than the original one but could just be the original looked bigger on film

Does it have a gas or diesel engine?

Was it built from scratch or converted from an existing boat?

Thanks for any insights!
