Default RE: Fin Size Isonic 125

Thanks a lot Roger and Ian,

It seems that iS hulls do not generate as much power as HSs so bigger fins go better (c/w HS).

The reason for my question was that I?ve just bougth an iS105 new but 2nd hand which came with the 34cm stock fin only.
I have a SR6b 38cm fin which I planned to use with 8.5 Severne OD sail on iS105. Probably not the best match from your answers but still ok I suppose.
Do you agree?
I also own a HS133 and untill I change it for iS133 by the end of this year, I could do with HSs fins.
