This is Gerstlaur's "Standard" model (well, this is the first to be realised, with on eother opening next year), but it's essentially just and off-the-shelf coaster.
This means that it requires no real land work, beyond site clearing and flattening. So the construction should be veyr fast. The ride has already been constructed and tested at Gerstlaur's factory, so there's less need for as much work onsite.
As such, Adventure Island have their fingers crossed for a Christmas opening.
This ride is amazing. Not so long ago they were turned down planning for a Gerstlaur "Bobsleigh" coaster (the Eurofighter's baby brother), yet within months, there's a full blown Eurofighter under construction. Shows what a little bit of money and effort can do for your seaside business
