Hi Dan, I can imagine that the leeward side of a sail has to be as smooth as possible. Also if battens are on starboard there will be more tension in the sail on starboard tack. However there are various opinions about how batten tension affects sail performance. Some will say just take wrinkles off, as most of the shape is given by downhaul and mast curve/stiffness.

|BelSkorpio||That's all very well, but a snowboard has no sail and I still prefer port tack anyway.|

It's actually less mystical and much more practical. The fastest sails are very sensitive to batten tension, and most sailmakers apply battens the starboard side of the sail. While much effort has been made to equalize the effect of batten tension between the port and starboard tacks, such as the modern batten tensioners seen on Gaastra and Maui Sails or alternating the side on which each subsequent batten sits.
Given the above and the need for very high skin tension, sails tend to represent the intended shaping when on starboard tack. This makes then more stable and probably faster on starboard than port, at least when all other things are equal.

Well, can't get enough of it,
I remember another test from an old gym teacher. We went with whole class swimming and he lined us up at the edge of the swimming pool, all next to each other and facing the water. Then he came behind us and pushed us one by one into the swimming pool.
He noted down with which foot we landed first into the water.
For more than 90% of the persons this corresponded with the preferred foot to take off for e.g. the long jump. Again, it's independant from the fact wether you're left-handed or right-handed.
It's a brain thing. It reacts in a split second and gives preference to a certain legg/foot.
It's that same foot that you prefer to have in front on a snowboard or surfboard.
For me it's my left foot, which means port tack.

|Farlo||Well, presumably I'm more of a right brain thinker (therefore fantasy ruled) but I don't understand why one should prefer port tack because of this. By the way I also prefer port jibe, which sounds a bit illogical. May be the push and drive of right foot?|

Sounds to me like you're brain is thinking pretty much the same like all men are thinking if they see a silhouette turning like that. LOL

For me, tacks are just the same for both directions, but jibing is a different story. Port jibe is my favored (right hand in front at the start). Starboard jibe has always been a bit less comfortable than port.
I have no brain so it must be something else.

|Farlo||Sorry Belskorpio but I see her turning clockwise, then counterclockwise, then clockwise again. It keeps changing all the time. With a bit of concentration I see also the image in full colors with some astounding details, hé hé...|

Ok guys do the test.
Are you a right brain thinker or a left brain thinker ?
Remember that the right brain controls the left part of the body. So if you see the danser turn clockwise, you're a right brain thinker, which means that you probaby will prefer port tack.
It's as easy as that. No exceptions. Haha
