Just chiming in as a local that the area is frequented by not just ships with professional equipment and captained by professionals but also by many locals out for a quick fishing trip, leisurely drive, or, in rare cases, quick trips using small fast craft. These are unlikely to notice a single swimmer with no marker.

A much more sensible option would be to rent a small boat in Bodø, or to charter someone to take you there and back again. If you have some time you could advertise in [the regional newspaper][1], or if you are in the region I would simply ask around the harbour.

If you're instead looking for a swimming challenge there are plenty of beautiful areas with or without small islands in the vicinity:

- Mjelle, a popular swimming and leisure spot.
- Sørfjorden in Mistfjorden, part of the new Sjunkhatten national park.
- [Vatnvatnet][2], except for the north-eastern arm marked "Heggmoen skytefelt", an army training ground.

Another option would be to take the "[hurtigbåten][3]" to any of several islands nearby.
