Porto Pollo Watersports

This page carries 11 schools. 11 are confirmed against the register. Read 2026-09-01.

Every one of them is here because the SSI, IKO and VDWS registers list it, and each entry links to the record it was read from. Nobody assessed any of them. Being in a register is not an inspection. Nothing on this page was read on the schools' own sites, so it carries no quotes and no languages.

Every watersports business in and around Porto Pollo that SSI or IKO or VDWS publishes in their own register of affiliated centres, read on 1 September 2026. 11 in total: 6 by SSI, 1 by IKO, 4 by VDWS. Each entry links to the register page it was read from, so the affiliation can be checked at the source rather than taken from here. 10 publish a website in the register. Absence means nothing on this page, and that is the important sentence on it. These are membership registers, not licences: a school that is not in them may simply not have joined, or may teach under a body that publishes no list at all. IKO's own site claims more than 350 affiliated schools against the 306 its feed carries, which is the size of the gap. So this page is what these bodies list here and never the schools of Porto Pollo. 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 none of these businesses was assessed by anybody for this page. Nothing here was read on the operators' own sites yet, so this page carries no training body beyond the register's own, no languages and no quotes.

On a dive page, Green Fins means a named third party visited the business and scored it. Nothing on this page is like that. What is here instead is a register entry: a body publishing the business in its own list, which settles that it is listed and nothing else about it.

What absence means here. A business missing from this page is one the SSI, IKO and VDWS registers list nowhere in this place. That is a statement about a list and not about a school: it may never have joined, or may teach under a body that publishes no list at all.

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.

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.
