I also have the F-Hot fins and I have never experienced vibration from them, what year are yours? Mine are 2014 shapes.

My F-Hot fins are from 2013 and they have nice finish. Both vibrates and I sail the 52 cm with JP SLW as well and it vibrates with this board also. I have tried with alu tape for the box and no differens. First I thought the F-Hot were faster than the S 10 but later experience is that I probably get best speed with the 51 cm S 10. I always use GPS. My thoughts goes to bying someting more exclusive, Z-fins or Select V Max. If I still can not get better speed it must depend on me, myself and I...

Sounds like the fins, perhaps they are too soft. Write to Steve and let him know. Just ordered some Techart fins in the bigger sizes so will see how they perform and will let you know.

Thanks mcross - I am interested how the new fin works!

I will see if it is possible to fix the F-Hots in box box (second time).

May have to wait a bit longer, they sent the wrong fin or the wrong fin was ordered by the importer, no idea which?

At least I now have several runs over 25 and one 26.34 knots with the F- hot 46 fin and TR 8 7.6. Mastfoot I tried 1-3 cm behind middle and footstraps back. The fin is a bit loose in the box and I will try to put some tape on it again.

Don't use tape, use primer and rub it back till it's the perfect fit

Pelegrin,
Use a thickened flattening/filler type of primer paint.
Coat it all over the root of the fin (not the foil of the fin).
When the primer has dried, it will add a few thousandths of an inch/
tenths of a millimeter to the thickness of the fin root.
Then use a flat smooth file or abrasive cloth on a sanding block to slowly
remove the high spots.
The high spots can be identified using a common bathtub bar of soap.
Rub the bar of soap over the built up surfaces (front/ back and both sides) of the
fin root.
Push the fin root into the fin box with fairly strong hand pressure, but no hammering or
pulling the fin in with the screws.
The shiny spots (where the soap has made hard contact with the interior of the fin box)
are what you need to file down/sand down/rub back.
When your fin fits at the correct height and has full contact on both sides in the fin box, then just work the front and rear tapers until the fin goes into the fin box snugly, but is still about 1/32" ( 0.8 mm) from being flush/flat with the bottom of the board.
Use the screws to "draw" the fin in that last 1/32" (0.8 mm) and your fin will be very
secure in the fin box.
If it still vibrates, when it's fitted tightly in the fin box, then the foil as a small problem.
Usually it's a tiny hollow area near the trailing edge of the fin foil.
Use your sanding block to level out the hollow and perhaps slightly blunt the trailing edge of the fin.
Hope this helps,
Roger
