DUNCANSON 35

About the DUNCANSON 35

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.

Designed by Allen Blackburne and built by John Duncanson, the Duncanson 35 is a robust cruising sloop with 400 hulls built. While the exact production years are not specified in the authoritative data, the boat is characterized by a displacement of 11000.0 lb and a comfort ratio of 24.51, indicating a stable, motion-moderating platform.

Best for:

This boat suits coastal and offshore cruisers who prioritize stability and comfort over high-speed performance, as evidenced by its high D/L ratio of 206.65 and low capsize ratio of 1.88.

Bluewater capability:

With a displacement of 11000.0 lb and a capsize ratio of 1.88, the Duncanson 35 is well-suited for bluewater cruising, offering significant stability and safety margins in heavy weather.

Comparables:

Comparable boats from this era include the Cal 35 and O'Day 36, which share similar displacement ranges and fin-keel sloop configurations aimed at comfortable cruising.
