A very long time ago worked I a board how a fextail. The last 70cm were in acryl, so
I could see all it what with the fin happend. I know what spin out is.I could all it see,
What I now work is only that what I tried good 20 years. Why work I asymm. fins for
tour and retour in one fin? No spin out, very fast and and they can be always 15%
shorter than other fins. Why are weedfins so fast ,or faster than upright fins.? Nobody
would hear that. Finish of the fin.? Look the fin of Martin. What is lift? How many % come
from the front, or from the bending fin.? A never ending story.
