Can a Hybrid Skimming Boat Revolutionize Lake Travel?

    Boat Lake
In summary, the conversation discusses the possibility of building a boat that can skim across the surface of a lake like a stone with occasional thrust from an engine. There are various concepts such as hydrofoil, ground-effect vehicles, and wing-in-ground-effect vehicles that could potentially achieve this. However, the drag coefficient and the need for a throttle man to prevent over-revving of the motors are important considerations.

Could I build a boat that skims across the surface of a lake like a stone and only needs an injection of thrust from an engine now and again to keep it going? Perhaps such a boat would have a rotating outer part and a stationary inner part for passengers.

If it would have to spin like the stone, that would be a bit of a tough nut to crack. I can't say I have seen it done, but there's nothing saying it can't. I think there would be a lot of trial and error.

Well basically if your boat s stable in still state. then a slight motor thrust from te rear should do the trick

Newton's first law... if you get the drag down near zero, you won't need much thrust. But even with a hydrofoil or related concept (how 'bout a ground-effect aircraft?), your drag will still be significant.

There's also the ever-popular wing-in-ground-effect (WIGE) vehicle. It's half-way between a hydroplane and an aeroplane. Google the 'Caspian Sea Monster' for an extreme example. :biggrin:

edit: How'd you sneak in there like that, Russ?

Well at any drag coefficient, the highest for boat is about 0.3, a motor can handle the job

Thr rotation of the outer part would need to be countered by the inner part turning slowly or some other way.

common ocean racers sort of do that
the boat flys between waves
thats why a throttle man is very important
to keep from over reving and blowing up the hi-powered motors
when the hull and props leaves the water
they are faster in waves then in flat water

both hydrofoil and air cussion craft don't skip

1. How does a boat skim across a lake?

A boat skims across a lake due to a combination of factors such as the shape and design of the boat's hull, the speed of the boat, and the properties of the water itself. The hull of the boat is designed to create lift and reduce drag, allowing the boat to glide smoothly across the surface of the water.

2. What is the difference between a boat skimming and planing?

While both boat skimming and planing involve a boat gliding across the surface of the water, there are some key differences. Skimming typically occurs at lower speeds and involves the boat barely touching the surface of the water. Planing, on the other hand, occurs at higher speeds and involves the boat riding on top of the water, with the hull partially submerged.

3. How does the weight of the boat affect its ability to skim across a lake?

The weight of the boat plays a significant role in its ability to skim across a lake. A lighter boat will have less drag and can achieve higher speeds, making it easier to skim across the water. Additionally, the distribution of weight within the boat can also impact its ability to skim, with a more evenly distributed weight allowing for better balance and maneuverability.

4. What are the dangers of boat skimming?

While boat skimming can be a fun and exhilarating activity, it also comes with some risks. Skimming at high speeds can increase the chances of losing control of the boat and potentially causing an accident. Additionally, skimming too close to shore or other obstacles can also be dangerous, as the boat may hit something or create a dangerous wake for other boaters.

5. Are there any techniques for improving a boat's ability to skim across a lake?

There are a few techniques that can help improve a boat's ability to skim across a lake. These include trimming the engine to the appropriate angle, adjusting the weight distribution in the boat, and experimenting with different speeds and angles of approach. Additionally, having a properly designed and maintained hull can also greatly impact a boat's skimming abilities.
