The sea is mostly free for all - it's possible to anchor up right outside the most exclusive properties in the Oslo area totally for free. In the summer time and shoulder seasons I'm often staying more in the boat in the Bærum area than at home (would totally have moved to the boat if it wasn't for the kids, school, kinder garden, etc). In the winter time I "need" land power, so I tend to keep the boat in the marina.

At the mouth of the Lysaker river it has been possible to moore up a boat totally for free right by the train station, something I've done frequently. It's ironic, the area is full of high-rise office buildings, making it quite much expensive to park in the area for people choosing to drive to work - I don't even work there, but I frequently "park" there for free, taking the train to work or home or wherever. The flipside is that one can expect a thorough beating around 07-09 and 15-17 when the express ferry to Nesodden is coming several times an hour, and even worse when there is strong wind from the south. The river bank is starting to get clogged up by wrecks moored up long-term, I suppose probably there will be some "no mooring"-signs coming up soon.

In the summer time there are also quite some "freaks" living in the river in Sandvika, in the guest harbour. One is supposed to pay harbour fee, and one is not supposed to stay there long-term, but quite many people stay there long term without caring to pay. The municipality is sometimes issuing warnings that the boats will be towed away, but they rarely follow up. It's a bit bad, as it's a nice and popular harbour, but often quite full.

One and a half year ago there were at least two boats anchoring up over all the autumn inside the Saraholmen island, using motorized dhingies to get too and from work via Sandvika. It's a bit yucky though - shallow water, popular bathing place ... and where does their sewage go? Right in the sea, I suppose. One of the boats also had to run a noisy generator in the evenings.
