Key West Diving

This page carries 6 schools. 6 are in the register and 6 name a training body. Read 2026-09-20.

6 are in the Green Fins and SSI registers, which are third parties saying the business is listed and nothing more. Everything else is what the school states on its own site, quoted and dated. Nobody assessed any of them.

Two kinds of source in one place, read on 20 September 2026, and absence means something different in each. 1 of the 6 is a Green Fins member, read from that register on 14 August 2026. Green Fins is the one source in this directory where somebody went and looked, and that one self-evaluated rather than being assessed in person. It is voluntary, so a business outside it is outside a scheme rather than below a standard. 5 are published by SSI in its own register of affiliated centres, read on 20 September 2026. Each of those entries links to the register page it was read from, so the affiliation can be checked at the source rather than taken from here. 6 of the 6 publish a website. Absence still means nothing on this page. These are membership registers and a voluntary scheme, not licences: a business in none of them may simply not have joined, or may teach under a body that publishes no list at all. So this page is what these bodies list here and never the schools of Key West. What a listing proves is narrow. It says the body registers this business, on the date given. It says nothing about the teaching, the equipment, the boats or whether the school is open this season, and nobody was assessed for the purpose of this page.

Green Fins means a named third party visited the business and scored it. 1 of the 6 here is Green Fins members. Each of those records shows the membership level, the assessment and the register ID. Nothing else on this page is like that.

What absence means here. Every business here is in one of these registers, so absence means the register does not carry the business, which is a statement about a list.

An equipment brand is not a training body. Several schools show Duotone, Cabrinha, Naish or North prominently. Those are gear sponsorships and certify nothing, so they are not recorded as affiliations, and a school that names only a brand shows a blank here.

A register entry can be opened; a claim cannot. Every affiliation taken from a register links to that body's own page for that business, so the listing can be read at the source instead of taken from here. Where a school's own words are shown instead, they are a claim with nothing behind them but the school, and they are labelled that way.

Why these registers and not others. A register earns its place here by being enumerable and citable: it has to list who is in it, and each entry has to have a page that names the business, so a reader can check the claim instead of taking it from us. Most do neither. Green Fins is the case that shows the difference, because its members are the best evidence in this directory and its member pages render the same bytes for a real centre and an invented one, so a Green Fins fact is stored with a centre id and never cited as a link. Twenty-five were tried and nine answer: what each one returned, with the date it was asked.
