Hi Klaus,

nice input!

About moving rigs. I find movement parallel to the sail surface to be unvanted and not comparable to pumping. Reversal of flow can never be good in my opinion. This is the movement (pitching) I think about when discussing movement. Movement in the other axises might be good but force lost due to elasticity does not sound good on a racing sailboat unless there are handling issues.
Stays that are "flexible" to a certain degree would improve on the jib, but starting to design this into the rig is very complex and with uncertain gains in my opinion. I would prefer to pull on some more downhaul and continue running the mainsheet and accept the jib draft increase.


Agree on the T foils! But they dont seem to be "in vouge" anymore.

5mm is probably a bit much but the matieral properties would be the deciding factor.


UV should not be an issue if the fibers are protected by a heat shrink tube. Epoxy is a well known property regarding UV and water. The remaining question is how water affects carbon fibers in the long run.



Very interesting discussion. Thanks for adding to it Klaus!
