The right-of-way rules in sailboat racing depend on who is on 'port tack' or 'starboard tack' (ie, they differentiate those mirrored halves). There's nothing physically special, though.

As mentioned in another comment, tacking (with its active directionality) is probably the closest to handed-terminology.
