Path: p Words0 QUESTION 2 When your group does this experiment, one person (at a time) will ride on the hovercraft, a couple of people will pull on ropes, and the remainder will mark positions of the craft. Please think about the important considerations for safety and obtaining good (qualitative) results What are important things for the person on the hovercraft to utilize it properly and safely? What are important things for the people pulling the hovercraft with ropes to test the previous questions accurately and safely? What would be a good way to mark the position of the hovercraft at constant time intervals? . .

Whilst the safety record of cruising hovercraft may appear to be good, this is largely an illusion - it only appears good because the poor reliability has limited the exposure to risk – usually the craft has broken down long before the owner can get into any kind of high risk situation! Engine Reliability:Your engine MUST be able to operate reliably when subjected to heavy water spray! Your craft WILL get wet and your engine WILL get water spray even if your have an engine cover (it's an aircooled engine and the incoming cooling air contains water vapour and droplets).
Do NOT use chocolate/terminal blocks or Scotchlock connectors under any circumstances – they are totally unsuitable!
In future, don't wash your engine using an engine cleaner or detergent or use a high-pressure power washer – they can remove some of the protective coating you have just spent a lot of time applying!
The absolute minimum requirements are that the craft must remain in a level and stable condition and not take on water when floating with the engine off whilst fully loaded and for an indefinite period of time. It must remain afloat when fully flooded and fully loaded or capsized. If you are unsure whether your craft is capable of doing this then check it yourself or ask the manufacturer or plan supplier – your life may depend on it!
ACTIVE SAFETY
Lifejacket: Auto-inflating types are strongly recommended, buoyancy aids or manually inflated types are simply not adequate. A lifejacket is your absolute last line of defence – unless your craft has sunk or is on fire, you should never get into the water - if you have no other choice then a lifejacket will improve your chance of survival.
Fire extinguisher: A fire on board any water craft is a life threatening situation simply because you can't get away from it! Your craft is almost certainly carrying a fairly large amount of volatile and explosive petrol – you must be able to quickly and efficiently extinguish a fire. The extinguisher must be capable of dealing with a fuel-fed fire and should be checked regularly (normally there is a pressure meter or other device to verify that the extinguisher is still properly charged). If you are forced to abandon your craft due to a fire then move as far away as possible from it to reduce the risk of being overcome by toxic fumes or burning fuel/debris (most hovercraft hulls are made from highly combustible plastics)
Marine VHF Radio: A radio is your primary emergency communication method. For most craft you should carry a waterproof hand held radio on your person at all times (if you fall overboard or are ejected from the craft then the radio is useless if it is still in your craft!)
