Hi onefoot,

You are correct in thinking that the 1.2 and 1.8 refers to a measurement that is taken at 120cm and 180cm from the tail (backend). The 1.2m + 1.8m measurements are standard points of measurement so you can judge the 'intensity' or 'acceleration' of the rocker line/curve.

On your Slalom 62, the planing straight refers to there being 760mm of flat surface measured from the tail and then it curves up towards the nose - a measurement that is taken while looking at the side profile of the board.

Tail and Nose measurements are taken at the actual nose/tail point.

Our graphics guy, OP, is in the process of making a glossary/info page which will be up soonish to make this information more visible for you and others.

Thanks for your question,

Mike

Hi Hans, great to hear the SL62 is working well for you, generally when we measure wave boards the straight edge will be touching the rocker line 1m from the tail.
