No, of course the word you're after is "tact". (And even as a foreigner, it annoys the heck out of me when people mix them up [which you didn't!], ususally as in "take another tact" when they mean "take another tack" [where 'tack' is a originally a sailing term for flipping the sail to the other side of the boat when going against the wind, IIUC; so the expression means "go in a slightly different direction"].)

I'm just riffing on Heikki's remark about foreign languages: In my primary language, Swedish, "tack" means "thank you" but is also often used for Eng. "please" -- so "Kan du ... , tack?" means "Could you ... , please?".
