The Black Soo is from 1957 and the Tarann from 1961 and both used what could be a modern ballasted keel. The Tarann was a more beamier boat however, even if the Tarann was not a beamy boat. Both had the same type of chined hull. Rge cabin of the Van De Stadt was better designed, at least aesthetically speaking since the Tarann offered more interior space.
The Tarann LWL was 8.10m nad the beam 2.66m. The Black Soo had a LWL of 7.90m and a beam of 2.13m. Both had about the same draft (1.75 and 1.80m) and had a big B/D ratio, most of it on their bulbs (48% and 49%). Both were considered very fast and seaworthy and of course, decades ahead of their time.
Here's a great photo of Stephen Buckingham's "turbo-ed" Black Soo "Starbuck", sailing off Tiburon, CA in San Francisco Bay. Note the retractable sprit and "square-top" main.
There are some great photos (and a video) of the boat's restoration on a Dutch site:
Wat voor boot is dit ???
I've seen the boat on several occasions, sailing on SF Bay, and it's a beauty.
A good thread about the design and about Starbuck and Mirage, in Sailing Anarchy, with very large pictures of the hull shape and keel, which also show the flared aft quarter section quite nicely:
