Smaller hover craft need to be lightweight yet durable
Building Hovercraft – Smaller hover craft need to be lightweight yet durable. They need to be able to get over the pressure wave known as Hump, when starting from an on-water start.
However, if you design and build a hovercraft that is very light, you risk making the craft endurable, so the design of small hovercraft can be a trade-off or balance between durability and performance. Many hobbyist suppliers make hovercraft from thin glass fibre – sadly these lack durability and do not last many seasons, often requiring expensive repair. The Hov Pod Hovercraft range is constructed from lightweight yet highly durable materials such as High Density Polyethylene and Carbon Fibre / Kevlar composites.
Small craft require engines with high power to low weight characteristics, so quite often microlight aviation engines are used. Depending on the design, some hover craft plow-in when crossing water, a term to describe a nose dive that can catapult the driver and passengers over the handlebars. There are many things to consider when purchasing or building air cushion vehicles, such as performance, payload when starting on-water, hump, plowing, durability, safety, power to weight characteristics of the engine etc. Hope you enjoy the video.
