Cheap swimming pools

In a weekend newspaper (can't remember which one) there was an article about how to cut the cost of public swimming pools. They used old cut-down parts of cruise boats - permanently moored in rivers - where the former purpose-built swimming pools took in sea water (which was twice treated to make it safe for swimming in and then twice treated on its way out to make it safe for fish).

Seaton is, of course, ideally placed for a salt-water tidal outdoor swimming pool. See here for such pools in the UK.

Lateral thinking - we need more of it.
