It is not that new an idea and well proven.
Boy, it is pretty tough to compare this to newer fin keel boats. This boat only has an 8 foot beam and its 40 feet long. And 50% of its mass is in its keel. And its hull is more V shaped than flat. The keel is longitudinally long rather than vertically long like a newer fin keel.

Because its so narrow and v-shaped, this will have a lot in common with the full keel boats. The full keel boats owe much of there sea handling capabilities to the hull design, not necessarily to the keel design.

I think the Valiant is probably very similar. Its hull design is more v-shaped than flat. This contributes immensely to its sea handling.

But you are quite right, the fin design and even the flat hulls have been around for centries.
