Overview
Norway is one of the more expensive sailing destinations — not because of charter rates, which are reasonable, but because of high Norwegian living costs. Food, fuel, and marina fees all run well above the Mediterranean.
Charter rates
A bareboat monohull runs $3,500–$7,000 per week; catamarans more. Given the demanding conditions, many sailors add a skipper (~$1,500/week). The fleet is small, so early booking is essential.

Running costs
Provisioning is expensive — budget around $95 per person per day. Marina fees average $60 per night, and fuel for a week of fjord cruising runs $350–$450. Bringing some provisions from home can soften the food bill.
Sample weekly budget
For 6 people on a bareboat monohull: charter $5,000, food $3,990, marina $420, fuel $400 — roughly $9,810 total, about $1,635 per person. Add a skipper for ~$250 per person.
