The sails & rigging

The Iris has a ketch rigging, this means that the rear mast (the mizzen) is shorter than the front mast.
As standard she sails with a mizzen, a main sail, staysail and two jibs.
Both masts can also be rigged with top sails. In light winds a mizzen staysail and a flying jib of 150 m can be added to the standard set of sails.
With all sails set the Iris can under favourable winds reach to between 8-11 knots (15-20 km/hour).
