Hmmmm.....it could possibly be adapted for Wellington/Wairarapa conditions. Perhaps half a dozen strategically attached small boat grapnel anchors buried in the gravel might do the trick.

Mind you the other weekend at White Rock I had, in 5 minutes, a wind shift of 90 degrees and from 10 to 70 plus kph as a pesky little front passed over. That might have been exciting.

And Corner Creek in Palliser Bay on a gusty day might be pushing the envelope a tad far. Worst case scenario - a stone flinging gust, I jump up and grab the roof to steady the ship, the grapnels pull out, I get tangled up and the whole nasty twisted mess blows into the sea.
