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.
