Hello all, Im new to windsurfing and took it up to get out in the water after work ,as sandgates only 10 mins away. Im often out there going through moments of grace followed by moments of total gumbiness

but only on a high tide as my 43cm fin likes to carve gutters thru the sea bottom . I was wondering how much i could cut from the bottom of the fin and the consequences of this. As the walk back in is a pain in the butt and wastes valuable daylight. My boards a 136l f2 with a 6m sail Is this a bad idea? your views would be much appreciated....cheers..mark
