Interior

The boat is equipped with 4 berths.


Rig

The Trækfuglen is equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a gennaker or a spinnaker for optimal speed.


Keel

The boat can sail close to the beach as the draft is just 0.21 - 0.31 meter (0.69 - 0.99 ft) dependent of the load. See immersion rate below.
