I like the catamaran-like hull shape because it gives huge amounts of stability for a relatively small displacement. To actually test the stability I’ve made a 1:10 scale prototype from styrofoam and hot-glue.
I did some test by adding the weight of a couple of people (to scale). The model kept beautifully stable. 2 people sitting on one side of the boat will not be a problem. She even managed to carry the weight of about 10-12 people without too much trouble.
