Oh go on, just one more before bed-time! Here I've used the remaining lengths of each spar ~ using the original 'good' end at the rear where we'll mount the motors ~ and fixed them to the bridge in the same way as the shoes were fitted previously.
Beginning to take shape now, we can see that the bulk of the buoyancy lies in the central bridge, which will form a static waterline. This will raise the 22" carbon-fibre airscrews half-way out of the water at rest, where at slower speeds they will act as water-screws.
At higher voltages the twin motors coinciding with the tail end of each boom will be able to drive the craft onto the plane, immune to damage from sub-sea obstacles, debris or vegetation.
The catamaran configuration will also allow the drone to emerge from the water in the shallows, recovering energy from the sun like a cold-blooded croc.
Shall we make it so?
