Since the designer is studying a 150 foot corvette concept, it’s most likely to be envisaged in the fast attack/missile boat role. That would probably mean that it is not meant as a dedicated blue-water platform.
Any 150 foot ship is meant for the ocean. It’s not for lakes and rivers. And any vessel that ventures on the ocean has to be ready for Sea State Ten. Mariners have learned this the hard way for a thousand years. See my above post about the ST-6 guys who drowned off Greneda because Chesapeake Bay training didn’t square with Caribbean wind and waves.
The same is true of this design. If it can’t handle Force Ten, it’s useless. A 150’ vessel on the ocean cannot always choose its sea state. And it can’t go into “Help me Mr. Wizard!” mode and disappear when the waves get big.
