to be fair we did see a video with water already, but these new pics are still great! [up]

Are you talking about one of the earlier videos (several weeks ago) that inadvertently showed water - or did the CHC see a more recent video in the last couple of days showing water?

Someone was moaning in the other thread that the concrete footers for the supports are below the waterline . Can't please everyone!

Last I checked, metal - when submerged for long periods of time can corrode from water / extensive moisture and other impurities within said liquid. Which down the road can compromise the integrity of said coaster or ride. [tongue]

which is why most coaster supports submerged in water are special coated against said corrosion right? [tongue]

This is either Brett saying that they are going to be fixed or that there is a complex custom support system in the works that causes failures if they corrode.

Something like what SymphonyX posted in the other topic is probably the most common solution these days:

This is what I wanted to comment on also. See picture below. Water looks good too! [up]

The top of the footers must be raised up so that they are higher than the water level. This is typical of all other steel structures like buildings and bridges.

Technically the steel supports still go under the waterline to the ultimate foundation, they're just surrounded by a ring of concrete and the water won't penetrate deep enough into the concrete to come into contact with the steel itself thus preventing corrosion.

Not really, the footers are just concrete poured over a rebar frame.

The steel supports are then just bolted on top. Encasing them in concrete would probably be a bad idea as would limit the steel's ability to flex.

If one has no understanding of why those are not completely under water you are right of course. [big grin]
The foundation is under water. The rest is not (bolts, support etc.)
