Notes

While the following statement is unconfirmed, it is said Duncanson saw the first S&S 34 arrive in Adelaide AUS and took photographs to copy the hull and rig. He then tasked naval architect Allen Blackburne to work from the photos to come up with the design for the Duncanson 35.

Thanks to Dragos for information, specs and sail plan.
