Hi Y'all, Hi Peter,
just saw your discussion...
Airboats come in all sizes, from Rotax 1-seater to 10 tons of cargo & 2,600 HP. Applications are:
- Tourism Eco-Ventures, Safaris, Birdwatching
- Film & Fashion Shoots
- Search & Rescue
- Nature & Wildlife Conservation
- Fishing
- Leisure
- Geometrics
- Law Enforcement
- Transport
Americans like aircraft engines, but try getting spares & Avgas in Africa. We use automotive (Chevy based & modified for airboating). Closed cooling circuit, no discharges into the water. Airboats will run dry ground if adequately powered, so no launch ramp required. Great for search & rescue, anti-poaching etc.
Propellers are carbon fibre these days, with re-enforced edges. Gear reduction to limit props to under 2500 rpm, so sound at pilot's seat about 85db. That's a lawnmower.
Comfy cruising up to 50 km/h, top speed 100. But that's scary.
Great visibility, you sit high up. safari, birding, fishing - awesome.
Models are here:

Only drawback: price of a luxury 4x4. Why? Really nice engine - 650HP - and carbon fibre prop. That's where the money goes.
SAMSA is cool with it, we are Cat.E certified.
We ride to slide!
