The Brederode lasts calculation

Tromp's flagship, the Brederode, is usually stated to be 300 lasts. I think that actually understates the size. If you do the calculation with Maas feet of 308mm, then the 300 lasts makes more sense than if you use the dimensions in Amsterdam feet of 283mm. The equation shows 300 lasts = (132ft x 32ft x 13-1/2ft)/K.Soliving for the constant K, we have K=190.08, which seems low. If we do it in Amsterdam feet, it makes less sense: 300 lasts = (144ft x 34.9ft x 14.73ft)/K. Solving for the constant K gives us K=246/76, which is high. In this case, the case for the calculation being done in Maas feet is not as strong, but it does seem plausible.
