Integration of the sea in game play

I will list ideas that have been made around the sea in the RP, The oldest is that of the ferrys (made by Hogom I think) that could extend the map to nearby islands like Sirroco and Soros. Like buses, this trade would have "lines of ferries" with its stations. We could have more houses on these islands. some trades require a maritime specialization like paramedic, taxidriver and policeman, for the following reasons:

• the police can not stop the fishermen with stars because they do not have a boat fast enough or means to bring back to the ground the wanted person, so a boat and a jetty for the police would be a good idea;
• the paramedic must have a helicopter to search for people drowned or who do not want to swim on 6 km (it often happened to me, I stayed on the roof of the boat by relaunching the fishing activity), I propose the "rescuers" they could intervene at sea as in mountain (below a bridge for example), they would have 2 sources of income, the taximeter and the /revive.
• taxidriver is the same idea as that of ferrys, it's just that in comparison busdriver, taxidriver have a functional trade in the utilitarian sense, I propose that ferrydriver have the 2 sources of income, make their circuits and transport the players.
