One way of comparing this designs to other is to calculate where the 150 kg crew needs to sit in order to put the boat at its intended waterline in absolutely no wind. This is then easily compared to the other F16's out there. Just test sail your own boat and see how far you need to sit up front in extreme light winds for the same to happen. The relative distance between positions is a relatively good indication how the volume is distributed. Is the bow more or less resistant to pushing its bows in.

We can then all do this measurement on our own boats and produce an overview and make founded design choice. More or less volume or a different distribution.

Can the software calculate the total volume of the boat. You want it at to be above 500 kg's or it will be a total dud for sitting to deep in the water.
