According to the VandeStadt website, the Caranan was a design that they sold the plans for, but it seems like they didn’t build any themselves; they don’t show any picture of a completed boat or a set of the plans. This means that builders (homebuilders, even!) perhaps bought the plans and then made…”improvements”. The keel does not look like anything VandeStadt would have produced. A boat advertised as a Caranan for sale in Holland does not look much like your photos. https://dailyboats.com/boat/31188-van-de-stadt-caranan-for-sale
