Svenska IF-båtförbundets forum

I am thinking of buying a IF.
I guess Marieholm made a few small changes to the IF over the years the design was in construction.
Can anyone point me to a list of those changes. It would be good to know if there was (if any) differences between a boat built in, say 1973 and a boat built in 1977.
many thanks

No considerable changes between these years of build.

Anyhow, differences in rig details may occur, i. e. mast beam colour and profile, type of mast step and different rig manufacturer. Also slight modifications of the cabin interior may occur.
