As a general rule, shouldn't DFT be less for a heavier skier?  (Assuming that the ski size remains the same)

Re: DFT

Thanks for responding and for the helpful website.  Apparently nobody who has read this has heard of an inverse relationship between DFT and skier weight.

Re: DFT

Besides obviously helping to make a tighter radiused turn by moving the fin Forward and a Larger Rad. turn by moving it back, the Horizontal move also controls the attitude of the front (tip) of the ski. A Fwd. move will lend itself to the Feeling of a shorter ski and a movement back will lend itself to the feeling of a longer ski. (but does not create more surface area...)

Any move should 1st be dictated by the performance of the ski. Skier wgt. alone would not necessarily mandate a fin adjustment. (Although wgt. could certainly be a slight factor either improving or reducing the performance.) But, if you factor in water temp. changes,  like very warm to cold and you are trying to find the optimum #'s for every 10 deg's of change. Then I think Body wgt. could possibly play an important role in dialing in a ski throughout the season. i.e. because we may start the season in 60 deg. water and wgh. 175, and end the season in 60 deg water, but wgh. 165...

The adjustment possibilities are endless!smile But then again, so are the endless ways to go wrong trying to adjust a fin...sad

Re: DFT

Well that old saying moving the fin back "makes the ski bigger" is true! Moving the fin back (DFT = less) reduces slip in the ski and also supports that tail more. So if you are a bigger dude you can look to a) add fin area or b) move it back. It will yield the same basic result.

PS = It's the same for softer water - either more fin area, say deeper or moving it back.
