Notes
- 5.5 US 69 "Sigma II" - boatyard confirmed to be Bj. Aas - 08.02.2019 by Kaspar Stubenrauch
- With the help of the DNV Stiftelsen Archives it is now reconfirmed, that "Sigma II" was built by Bjarne Aas.
- 5.5 US 69 "Sigma II" - boatyard? - 30.01.2018 by Kaspar Stubenrauch
- As we do have a Lloyd's Register note saying, that there was an N.G. Owens designed and Vator built (1963) boat called "Sigma", question is, which US-sailnumber she had.
And, which boatyard built 5.5 US 69 "Sigma II"?
