Hi Christian, Currently only marine related POIs are included in the chart so there shouldn't be things like ice cream parlours. In regards to roads, I suppose the best solution would be to only include roads, buildings, and useful POIs that are within 5km or so of the coast. However, I don't know a way of filtering the OSM data to remove data not near the coast or a waterway.
