Hi,
I stored my boat in Bergen this winter, at Bildøy Marina:

The cost was approx €1,203 from October to April (£1,031). They charged 450 NOK per foot (€38 or £33). My boat is a
Hallberg Rassy Monsun 31. This cost included lifting and powering
washing, storage, and putting the boat back in the
water. They charge extra for electricity- a small standing charge of around €15 per month and then whatever electriity you use. I had a dehumidifyer hooked up and it cost approx €35 per month.
I would have been allowed to stay on the boat if I wanted, but they have no toilets or showers. They were very helpful, they stored my starter
battery inside and even gave it a charge in January without me asking them to.
Transport to and from Bergen is easy, bus number 360 from the central bus station to the bus stop here:

Takes around 30 mins and regular buses.
My boat is registered in Norway, but i'm not sure they care, they didn't ask me for any information about that or
insurance.
One thing to note is that just outside the marina there is an electricity line that's at 20m, so bear that in mind for the height of your
mast.
Hope that helps,
Richard
