hi guys ,
In europe all boats build from +/- 2004 till now have hulls canted out by +/- 4 degrees and daggerboards canted in by +/- 7 degrees ( all relative to the vertical plane ).
all boats fit the box rule of << 2300 mm when pulled fully up and >> 1500 mm tip to tip when down
actually most canted boards are +/- 1700-1800 mm tip to tip.

the most extreme curved boards on Bob baire boat are 1580mm tip to tip.

as you see no huge differences between the curved and canted boards
