Combine both hobbies, i.e. Seaplanes,floatplanes. Yoi could even use a boat as a tug incase you end up dead stick in the water. Would need some kind of good prop shrould on the airboat though. Airboat prop + plane = ouch
I've had thoughts of building a hovercraft using an air screw (prop) to power it. Inflatable bag underneath and the whole bit. I would just need to build it should the engine quit that it not sink.
I have too many ideas to put into motion all at once - my wife would never see me...
I would like to build a glow powered rescue vessel, but I have other ventures that have priority right now.
