Motorless Water Drone
This motor-less water drone is a low cost alternative to a fishing bait boat, or just a way to observe fishes without disturbing them. There is no prop noise. There's nothing flying around in the air (as with an aerial drone or kite). You can stand or sit some distance from the water, so fish won't see you.
It's just a fish shaped body powered and controlled by a fishing line. You can use brief tugs to propel it away from you.

Motorless Water Drone This motor-less water drone is a low cost alternative to a fishing bait boat, or just a way to observe fishes without disturbing them. There is no prop noise. There's nothing flying around in the air (as with an aerial drone or kite). You can stand or sit some distance from the water, so fish won't see you. The waterdrone is shaped like a fish turning to one side, and it's slightly buoyant. If you pull on the line, it will "glide" forward while being pulled toward you. This gives you maneuverability "sideways" and toward you. However, if you let the line slack, the waterdrone will turn away from you and coast a bit of distance away from you. After it turns roughly 180, you give at a brief tug to make it roll 180 and give it a bit of momentum. This lets it turn away from you again. Timing the tugs lets the waterdrone move away from you meandering left and right. This waterdrone can have two "eye" cameras to let you observe fish and stuff underwater. #gizmo
Balloon-Kite Sailing
"Balloon-Kite" Sailing is a leisurely alternative to kite boarding. You sit underneath a balloon on padded lines, lifted mainly by aerodynamic lift rather than balloon lift.
If the wind is inadequate to lift you above the water, you can still at least sit in the water and sail downwind.

Balloon-Kite Sailing
Balloon-Kite Sailing I imagine "Balloon-Kite" Sailing to be a leisurely alternative to kite boarding. You sit underneath a balloon on padded lines, lifted mainly by aerodynamic lift rather than balloon lift. Balloon tilt provides lift; aiming the balloon off to a side provides reaching thrust. A floating board with vertical fins acts as your keel. Even if the wind is inadequate to lift you above the water, you can still at least sit in the water and sail downwind. The drag of the balloon means that this isn't going to be fast compared to normal kite sailing, but I see this as more of a relaxing activity enjoying the view than a serious form of transportation. #gizmo
"Aeroramjet" is a counterintuitive concept opposite of aerobraking. An aeroramjet maneuver through Jupiter's upper atmosphere could accelerate you by 10km/s, resulting in a 35km/s interplanetary velocity thanks to the Oberth effect.
Your craft is pulled by a magsail, using a nozzle to spray inert propellant into the airstream. The resulting plasma pushes the magsail forward, accelerating you.
Here's an X-Bow inspired rocket ship. The main rockets are to the sides of the bridge, kept above the water.
It lands by dipping its tail in and then flopping forward onto the water.
During launch the angle of the rockets lifts up the nose before the vessel fully emerges from the water.
So, I was browsing @nyrath 's Atomic Rockets site and came across the idea of spraying instant landing pads by injecting stuff into the lander's exhaust:

This is relevant to a pet ISRU idea I have for CO/LOX+regolith dust propellant, mining Deimos for regolith dust and using its momentum to gather CO2 while aeroscooping to low Mars orbit.
If you dump the dust overboard, the CO/LOX lacks "oomph", but injecting it into the exhaust gives you nice performance.
This rocket ship has it all. Pilot with pointy head. Coal power. Propeller in case rockets don't work. Big empty space because they ran out of ideas of what to put in it.
