maybe we get this up and running?

We don't have to - Olaf has a much better scheme & it is visible right now. Find a harbour or marina and click on it - details will appear.
The OSeaM scheme was to try and import & merge data from disparate sources, most of which provide inadequate details or poorly located positions. The problem then remains how to maintain this data? When the original sources are updated, our import would become stale, so requiring constant re-importing and editing. Nobody has time for this!

yes, Olaf also implemented the overpass.api query (so (only) the first part is done).
I am asking for extending this feature: Query skipperguide (or other sites of interest) on demand and serve the corresponding hyperlink...

The best way to do that is to add links to the various marina guides to the harbour object. That way, clicking on the link (which also would have to be displayed in the pop-up panel) will take the user to the up-to-date entries in those guides. We can then encourage to operators of those sites to add the link tags in the areas that their guides cover.

Disagree:
- adding and maintaining links to OSM-db will be a pain
- this also applies to seperate 'harbour-db'
Example:
- click on harbour icon 'Alter Hafen Wismar'
- pop-up key=value box
- offer 'search skipperguide' button/link
- do query (new window/tab)
-- eg. https://www.google.de/search?q=osm+tags … erguide.de
-- or https://www.skipperguide.de/mediawiki/i … l&redirs=1
-- ...

A link only has to added once, whereas the data linked to will be constantly changing. Also it will not be us who add these links - it is the DB operators who would be encouraged to do that work.
- click on harbour icon 'Alter Hafen Wismar'
- pop-up key=value box
- offer 'search skipperguide' button/link
Remember 90% of viewers are not mappers - they will not understand keys and their values. Any pop-up box must translate key/value pairs to plain language.
The scheme has to be global, whereas the various harbour DBs only have local extent. Therefore offering specific DB buttons would not be a workable scheme.
If we were to have tags of the form: website:<DB name>=<DB URL>, then harbours/marinas/anchorages with these tags would present the link(s) in the pop-up.

I did a short test to search harbours in skipperguige by OSM name. This fails every time. I have tested 10 harbours in wide areas of the Baltic Sea. Seems to be no solution.
One of the biggest problems is, that skipperguide does not use the official name of the harbour only the place name e.g Yachthafen Burgtiefe will be named only Burgtiefe. If it is possible, that skipper guide uses the official names of the harbours, it should be possible to open the page via "search=Yachthafen+Burgtiefe" argument in the url. All checked harbours have the official name in the OSM db.
I found no other tag in the OSM db that is reliable enough for doing a search.

quick research at skipperguide (profile=all) :
Heinz-Schleußer-Marina > fails
Ruhrorter Yachtclub e.V. > Rhein-Herne-Kanal
Jachthaven Friese Hoek > Lemmer
Regatta Center Medemblik > fails
Pekelharinghaven > Medemblik
google (site:skipperguide.de):
Heinz-Schleußer-Marina > fails
Ruhrorter Yachtclub e.V. > Rhein and Rhein-Herne-Kanal
Jachthaven Friese Hoek > IJsselmeer and Lemmer
Regatta Center Medemblik > IJsselmeer
Pekelharinghaven > IJsselmeer
I consider a google-search as a helpful add-on.

I do not like those "let me google for you" buttons. Each user can do this on his own. I am searching for a solution to properly open the corresponding skipperguide page at the moment. Adding a google search feature should support other providers as well.

Google is a commercial bloodsucker.
