He has just had confirmation on resource consent and an civil aviation sign off for a 100m high swing, which is big enough for four people to swing above a gully on Karioitahi Beach at any one time.
“A swing offers a two-way experience unlike a bungy jump that goes straight down. It also is a better way to make great recordings. The winch that takes you up to the top can run at variable speeds, so it can be stopped to enjoy a view or have a conversation with each other and the operator on the ground. It is controlled from the ground,” he says.
Flyers will lie prone in a harness, pretty much the way hang gliders do and they will wear helmets that have an audio system as well as a video camera, so the trip can be recorded for posterity. Their flight is controlled from the ground and the flyers have no control over what happens once they are strapped in.
The swing set-up will have three solid steel rods positioned in a lattice format with 100 supporting guywires, which is visually inoffensive, says Mr Giltrap.
The flyers step into the swing in full safety harness on the ground and are slowly hoisted to the top.
Anyone over the age of 10 can enjoy the swing and only serious health issues will prevent anyone from taking part.
He expects to be able to build the swing over the next summer and believes that his swing will be the worlds highest. He sees many benefits for the region in terms of tourism.
The swing will be made in Australia.
Swings exist elsewhere in the world, such as in Florida, in Sochi, Russia and the Nevis swing in Queenstown. They all have a good safety record, Mr Giltrap says. Waiuku firm, Mechanical Design and Development Ltd, have been consulted on the project, but the expertise to build the swing is not available here.
Mr Giltrap owns a piece of land overlooking the beach where the swing will be built and says the spot is easily accessible.
