Can You Use a Raft as a Hovercraft?

  • Thread starter Piper84
  • Start date
In summary, the conversation discusses the possibility of using a raft as a hovercraft by installing a pillow bladder type skirt and a hard deck. The idea is to create air flow and lift by placing holes in the upper inside of the raft and using a 15 hp engine with a ducted fan and controlled vent. The conversation also mentions adding a check valve to keep air flowing in one direction and the stability and weight considerations of using a raft as a base for a hovercraft. It is suggested to search for hovercraft kits with a recommended engine size of 8 to 15 hp for a 400 lb. gross weight.

Use a raft as a hovercraft by using a pillow bladder type skirt. Installing a hard deck in raft and securing the skirt in center forming a pillow around outer edge of raft. Then placing 2 in. Holes in upper inside for air flow and lift? Can it work?

Welcome to the PF.

What are you going to use for an engine and propeller system?

Thinking of a ducted fan with a controlled vent at the base of duct to direct some air flow for lift. Also add a check valve to keep air flowing in one direction. With a 15 hp eng. the deck dem. Are 5 feet by 12 feet I think it would only take 1.5 hp for a .5 in lift at a gross wt. of 350 lbs. and the rest for thrust.?

By starting with a raft my thought is keeping the craft light just hope it will be stable and not flip.

Try a Google search of 'hovercraft kit'.
400 lb. gross takes an 8 to15 hp engine.
 

1. Can a raft be used as a hovercraft?

Yes, a raft can be used as a hovercraft. However, it may not have the same level of performance or control as a traditional hovercraft.

2. How does a raft function as a hovercraft?

A raft can function as a hovercraft by using air pressure to lift the raft off the ground or water. This is achieved by using a fan or propeller to create a cushion of air underneath the raft.

3. What materials are needed to turn a raft into a hovercraft?

The materials needed to turn a raft into a hovercraft include a fan or propeller, a motor or engine, a steering mechanism, and a skirt to trap the air under the raft.

4. What are the benefits of using a raft as a hovercraft?

Using a raft as a hovercraft can provide access to shallow or marshy areas that are not accessible by traditional boats. It can also be a cost-effective alternative to purchasing a traditional hovercraft.

5. Are there any safety concerns when using a raft as a hovercraft?

Yes, there are some safety concerns when using a raft as a hovercraft. It is important to follow proper safety protocols, such as wearing a life jacket and using caution when operating the raft in rough or windy conditions.
