I've been scoping out the area that Drayton has to work with here if the rumours in the video are true on Google Earth, and it's a surprisingly small area on the face of it, but one that does carry a fair few options if Drayton think outside the box a little.
If my Google Earth snooping proves that I properly know Drayton, then I ascertain that the largest base area they could possibly have is this one:
(I apologise for my slightly crude drawing...)
I've calculated the site area of the highlighted plot to be around
4,000 square metres. For some idea, that's about 25% larger than the area inhabited by Spinball Whizzer at Alton Towers (a pretty compact ride that is half the track length that this is said to be), and it's a smaller area than both the Buffalo (~5,000) and Shockwave (~9,000) in terms of site area in square metres. At its extremities in each dimension, the site is approximately
65m wide and
73m long.
Chall's video says that this ride's track length will be approximately 800m. If that is true, then assuming the coaster kept to the highlighted area, this ride would have a track density (metres of track per square metre) of around
0.2 metres of track per square metre (800m of track within 4,000 square metres), which for some perspective is ever so slightly more dense than Smiler at Alton Towers, whose track density is
0.195 metres of track per square metre (1,170m of track within 6,000 square metres, according to Gerstlauer). That ride was said to be the most track-dense coaster on earth, so if Drayton is building a coaster in this area with the rumoured specifications, then it will either be
very, very tightly packed in...
...or it could span to other surrounding areas. I could potentially see it going either behind Buffalo, towards the lake (if they removed Flying Dutchman), or both. For some idea, Wakala at Bellewaerde (a Gerstlauer like Chall cited, and also the type of ride I could imagine Drayton going for) is
87m wide and
84m long according to Gerstlauer (
https://www.gerstlauer-rides.de/references/reference-list/europe/belgium/wakala-en-us/), which I calculate could fit if they stretched outside the given area. Assuming the ride's turning point was somewhere around the centre right of the plot I identified (so sparing the toilet block below), a ride with Wakala's dimensions (assuming a perfectly l-shaped layout, of course, although I know Wakala is quite long and thin, so it might fit) would come to around Buffalo's s-bend horizontally and around the tree between Flying Dutchman and the lake edge vertically:
The only slight stumbling block is that this ride would be
800m long, while Wakala is
655m long as per Gerstlauer, so it would be a little longer, but I guess they could just make it a slightly twistier ride, to use up that empty surrounding space within the Apocalypse/Pandemonium/Test Track plot!
In terms of the Zamperla Family Launch Coaster; I could definitely see it! According to Zamperla's website (
https://www.zamperla.com/products/family-thrill-launch-coaster/), the stock model is
112m wide and 52m long, which within Drayton's plot would look something like this:
Or like this:
(It would depend on which way they decided to orientate it)
However, the stock model is only
519m long (rumoured length is
800m), and I was unsure whether the footprint of the layout Zamperla are promoting would be thin enough to fit in the given areas, so it might have to be custom.
So to wrap this up; the base area is quite compact, but I think some kind of family launcher could certainly fit if Drayton thought outside the box a little!
