Sorry guys, wrong thread, will try to take it to general.

It probably is a "handed" issue, but there's 2 possible other causes.
If your in the harness, your harness lines may be out on you starboard side. The other thing is your sailing line you may be going more downwind on the port tack and more upwind on starboard.

Think about if you a natural footer or a goofy footer. i.e which leg goes forward when you try to skateboard or surf. This will be the direction which you will have better balance and feel more comfortable.

shwell,

I'm a goofy footer and to be perfectly honest feel no difference whether I'm on a starboard or port tack - I can jump just as well on either tack.

A bit of perserverance is all that is required if your natural 'footedness' is causing this problem.

I agree that although you may sail better on one tack because of better balance, practice and perserverance can overcome this.

I am a natural footer but ironically I jump much better goofy footed. Why... because I jump a lot more often in that direction.

We're all somewhat laterally biased. It seems to me to be mostly related to our regular sailing site. Where I sail its starboard tack out in a southeaster and when a noreaster blows we mostly sail around the other side so its still starboard tack out. I didn't realise this for some years and I've developed a tolerable quick tack to port because I always do it on the inside but my tack to starboard is woeful because I do it in the bumps on the outside. I have a similar bias with my jumping - starboard tack is ok, port is really awkward.
Now I try to ensure I give equal time to all moves on each tack.
