Hi OpenSeaMap!

I want to support what Pieren is saying!!!!

Having started to tag lakes and harbors all around Switzerland, I realized that:
1. The OpenSeaMap tags and OSM tags do not match.
2. Most of the tags are not rendered.

This situation is a pity. I do not want to live in two different worlds. So I really suggest that OpenSeaMap uses standard tags where possible, and clearly documentating things. This will very much improve probability that mappers will map and renders will render!
