Actually, English Heritage doesn't have a '30 year rule', that's national government policy on listing.
English Heritage is the government's advisor where listing buildings is concerned, but it's not the sole source of input, and it is the Secretary of State who actually has the decision to make on listing.
Getting anything post-war listed is very, very difficult, and I think the possibility of getting anything 'ride' connected listed from 1986 just about impossible, frankly. Even after 30 years, it would have to be be something very special indeed, significant in historic terms, not simply the last one left etc. More likely would be the listing of a building around it, but again, it would have to be something very significant (like the Royal Commonwealth Pool in Edinburgh).
Not sure if Hove is significant enough to be listed, although its history is certainly fascinating:

but the slides were closed in 2000:

and according to this are now demolished:

All rides so far acquired for Dreamland (including the parts from rides rescued from Southport and the Rhyl waterchute) have been acquired by a dedicated band of people doing this in their own time, and for some of it there has had to be an appeal and campaign members have clubbed together to try to cover the costs of purchase, transport etc.
There is no major pot of cash available to simply step in and rescue anything, no matter how desirable, and space at Dreamland is going to be limited.
As far as 'aquatic architecture' is concerned, in the sense of historic 'amusement park' structures, which is really what this campaign is about:
There is a waterchute listed, at Grade II

Enjoy state-of-the-art water play, old and new, at East Park - 09/07/2009
Hull's brand new water play feature will be formally opened by Deputy Lord Mayor Cllr David Gemmell on Friday 10 July at 1pm. Cllr Gemmell will be joined by children from Westcott and Alderman Cogan primary schools.
It's the second time that East Park has become home to state-of-the-art water features. The inauguration of the new water play area coincides with the 80th birthday of the ever popular Grade II listed water chute, one of just two remaining in the country and the only one still in public use.
At 120 metres long, the new water play area is perfect for keeping cool on a hot summer's day. From a large bowl shaped paddling pool, complete with water jet cascades, the water meanders through rocks and boulders down to a second paddling pool. The new feature is not just for play, already it is being used for educational purposes. Having been fitted with an Archimedes screw, children can learn the principles of water displacement and how ships are lifted out of water, as well as how river deltas are formed.
The new feature is set in one of the most mature areas of the park where the original, and then the only, water was located. Thanks to funding from the Heritage Lottery for the play area, water has been restored to its earliest site, putting a modern twist on borough engineer Joseph Fox Sharp's original plan for East Park.
When the historic water chute opened in May 1929, it was all the rage as a "white knuckle" ride! Crowds were happy to queue at length just to experience the thrill. Nowadays, it is still in full working order, opens in the summer months and remains a traditional favourite with East Park visitors. The Friends of East Park will mark its official birthday on Sunday 23 August from 12 noon onwards when the ride will be free to anyone who brings one old penny, the original price for a child to ride down the chute. Adults were charged the princely sum of tuppence!
East Park is Hull's largest park, covering approximately 120 acres (48 hectares). The western side of the park opened to the public on the 21st June, 1887, the day of Queen Victoria's Golden Jubilee.
Nowadays, it is an award winning park with something for everyone. There are boating and model yacht lakes, animal education centre, deer park, football and rugby pitches, bowling greens, woodland walks, beautiful formal and sensory gardens, café, superb children's play areas, fishing and more. Furthermore, it is fully accessible for people who may not be as mobile as others because there are four motorised scooters and four manual wheelchairs available to help them enjoy the Park's attractions.
Holderness ward councillor John Nicholson said: "East Park is an absolute gem and a great asset to the city. It offers tranquillity and relaxation and caters for most sports and interests. The new play feature is yet another plus, and enables an interesting comparison between the most modern and the best in the 21st century with its counterpart 80 years ago."
