vhf for leisure=marina

[PanderMusubi]

General

Affected tag(s) to be modified/added: vhf
Question asked: What is the VHF channel to contact marina XY?

This information is usually posted on a sign when entering the marina or available on sailing boats and motor boats that are locally rented. This information is important to contact the marina to enter it safely in certain conditions when the sign cannot yet be read from a distance.

Checklist

Checklist for quest suggestions (see guidelines):

• 🚧 To be added tag is established and has a useful purpose
• 🤔 Any answer the user can give must have an equivalent tagging (Quest should not reappear to other users when solved by one)
• 🐿️ Easily answerable by any pedestrian from the outside but a survey is necessary
• 💤 Not an overwhelming percentage of quests have the same answer (No spam)
• 🕓 Applies to a reasonable number of map data (Worth the effort)

Ideas for implementation

Element selection:
Integer as described in wiki. Give warning (are you sure) when entering 16 (emergency channel). Perhaps also for some other channels later. Don't use leading zero.

Metadata needed:
leisure=marina

Proposed UI:
Prefill with previous value. Some countries use the same for these harbours.

It should be noted that there are also inland lakes where this information is not relevant and not known. I'm from the Bodensee (Lake Constance) in southern Germany and have seen this information neither in the theory course nor in the marina itself anywhere.

Closing because

• the VHF is not signed everywhere
• very low usage numbers
• most importantly, users will not know where to look for that. There may be many numbers at a marina

[PanderMusubi]

@westnordost and if at least one of the (type=multipolygon) members of leisure=marina has the tag natural=coastline, would that filter out the inland marinas?

[westnordost]

And you assume that every marina that is located at the coast will have a prominent sign denoting its radio channel, visible from the street?

[PanderMusubi]

No, is more for an app called WaterComplete. ;-) But I use also StreetComplete from the water by the way.

[westnordost]

I think every door is noch better suited for that ist case. Vhf is part of the id presets so it should be displayed for marinas(?)

If street is waterway, then yes.

You will mostly see the sign only from your boat. Some random examples:

The information is definitely very important and valuable, but only answerable to SC users with a boat from my point of view.

By the way, I have added a picture to OSM Wiki regarding this. https://wiki.openstreetmap.org/wiki/Key:vhf
