I have been thinking along these lines for some time now as I searched for a
short, wide, open-transom tender/dive craft that could be carried (two of
them) on the front deck of a 65' gamefishing catamaran of my design,
I was seeking a relatively small tender craft that comfortable could carry 4/5 persons with some dive and/or dive/fishing gear. Too many of the existing RIBs are too confining in their interior space, particularly those made to conform to road towing widths. I wanted two persons to be able to sit on the tubes across from one another, and yet still have the leg-room to clear a central straddle seat that might house the jet ski type power plant. That would call for a fairly wide craft with a central hull that could house the water jet. A very wide craft needing a central water hull rules out the cat configuration. I could have a transom for its structural contribution, but it could be open to allow for immediate evacuation of any water that might swamp it as a result of a large wave washing over the bow stowage area of the mothership. With width I could accommodate the people without excessive length and thus keep the boat size small for the continuous hoisting service it will see.
