@Zman I have mixed feelings about the venue/spectators.
For one, I've had some conversations with the organizer in Malaysia, and he seems like a good guy, one of a handful of passionate promoters in Asia, where the sport is growing (albeit in relative terms, from 'almost nothing' to 'really small'). As noted in another thread, the lake (& his ski school) has has more protected areas, but obviously you use the already-built grandstand area for this kind of tournament.
It makes some theoretical sense to try to have major events in large metropolitan areas — even if that means sacrificing perfect man-made-ski-lake-in-the-middle-of-nowhere conditions — in order to promote the sport. On the other hand, if you've ever been in a business selling something consumers don't seem to want, you know it can feel like "pushing on a piece of string". The IWWF seems to have a mandate to promote waterskiing around the world (see below), but that doesn't mean the world is "buying" (ie. non skiers coming out in droves to watch big tournaments, like non-racing spectators come out to NASCAR races).
Remember, if we complain about important tournaments being held in crappy sites in metropolitan areas, we don't get to also complain about how our sport isn't growing outside of our passionate little community of folks who either live or drive out to exclusive/expensive man-made sites to ski (there's of course a lot more to the problem of our sport not growing, of course).
For reference: 2019 Worlds: Putrajaya is a planned city in the outskirts of Kuala Lumpur (~8 million metropolitan area), accessible by public transit; 2017: in the outskirts of Paris (~12.5 million metropolitan area), accessible by public transit (crap weather unfortunately, so again, poor spectator turnout) vs 2015: man-made lake in Lake Chapala, Mexico, an hour's drive from Guadalajara (~5m people), no public transit (IIRC, this was a last minute thing after Italy pulled out from hosting?), and 2013: man-made lake on the outskirts of Santiago, Chile, kinda-maybe-accessible by commuter train. 2011 was outside Moscow, 2009 was a club site outside Calgary. The last time it was hosted in the US was 2003 (Florida), and before that, 1989 (Florida).
