David de Wildt's entry for the Calmer Sleutel

The Calmer Sleutel was hired by the Admiralty of Rotterdam and served with the fishery protection squadron. The Calmer Sleutel was lost on 22 July 1652. David de Wildt's entry makes me think that the dimensions are in Amsterdam feet: 103ft x 25ft x 11ft, with a height between decks of 6ft. Ron van Maanen says that the crew of the Calmer Sleutel consisted of 90 men. The armament was 8-8pdr, 6-6pdr, and 6-3pdr guns. The modern spelling is Kalmar Sleutel. Sources:
