Sesimbra Watersports Schools in the RNAAT Register

33 schools teaching scuba diving and surfing. Every one of them is here because the RNAAT register lists it, and each entry links to the record it was read from. Nobody assessed any of them, and 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.

33 schools read on 2026-08-20 · 33 confirmed against the register · 0 languages named in total. Read this differently from our dive pages: those list every operator a register carries and show who was assessed in person. This one lists every school the RNAAT register carries here, all 33 of them, and nobody assessed any of them. Being in a register means the body says the business is listed. It is not an inspection.

Every business the Portuguese state licenses to run board sports or diving in the concelho of Sesimbra, read on 20 August 2026. All 33 carry an RNAAT number, the licence a business must hold to trade in these activities, which Portuguese law requires it to print in its own material, so the number here can be checked against the school. 23 hold the board-sport item and 18 the diving one; 24 publish a website in the register. Absence means something on this page. A business missing from it is one the register does not license for these activities in this concelho, which is a fact about the business rather than about the completeness of a list. The boundary is municipal, so a school a few kilometres along the coast is licensed by the same authority and appears on its own page or on none. What the licence never says is which sport. Surf, bodyboard, windsurf, kitesurf, skim and stand up paddle are a single item in it, held by 1,300 businesses across Portugal, so the state licenses board sports and says nothing about which of them a school teaches. Nothing here was read on the operators' own sites yet, so this page carries no training body, no languages and no quotes, and nobody assessed any of them.

How to read this list, and why it is weaker than our dive pages

On a dive page, Green Fins means a named third party visited the business and scored it. Nothing on this page is like that. Every value here is a claim the school publishes about itself, which we opened on the date shown and quoted rather than summarised.

What absence means here. On a dive page, absence means the operator is not in the register. Here it means we did not find the school, which is a statement about us and not about them.

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 named body is still only a claim. None of these schools publishes a membership number, so there is nothing to take to IKO or VDWS and check. If you care, ask the school for its number and ask the body to confirm it.

Why no register stands behind this page. We have tried eighteen governing bodies and state registers, from IKO and VDWS to PADI, SSI, and the tourism authorities of five countries. Four can be read in bulk and none of the four covers these places. The full account, body by body, with what each one actually returned, is on why no register stands behind these pages.

What this page is, and is not. This is independent research by the operator of this site, not reviewed by a lawyer. A listing is not a safety endorsement and not a substitute for training: we have not taken a lesson with these schools, inspected their equipment or watched a briefing. Kitesurfing, wing foiling, windsurfing and surfing carry risk that no listing removes. Nothing here was checked by anyone but the school itself, instructor teams change between seasons, and the date beside each field is the day we read it and nothing more. Confirm anything that matters with the school before you book on the strength of it.

Corrections and removals

If you run one of these schools and a field is wrong, write to us with the page that shows it and we will correct it and date the correction. We do not charge for a listing, for its position, or for its removal, and if that ever changes it will be declared here and on the disclosure page before the first paid listing appears.
