Let's have a look at what's going on here:
When you kayak across a river it's not as simple as going straight from A to B. The flow acts on the boat and you get pushed down-stream like this:
It looks like you've been getting pushed down-stream but turning the boat a bit along the ways so your path looks like this:
So what's the best way of getting across?
Rolling a sea kayak is more an art form than it is a paddling essential. Self-rescue and long-distance swimming techniques, on the other hand, are skills every sea kayaker needs to master IF he or she ever intends to paddle alone.
It's one thing to know how to intentionally roll a kayak, but quite another to get knocked over by an unseen wave and retain ...
Well, your weight distribution is important, the heavier the side "close" to the wind is, the straighter you will go, but there is an other point : your path is different of your direction.
In fact it's about forces applied on your boat (same as flow).
It's a simple vector addiction :
I hope it helps you.

Interesting, this depends on what kind of boat you're in.
I'm going to guess that you're in a sit-on-top or something similar and/or have a much heavier person in the back?
It this case the turning is probably down to the wind acting directly on the boat.
The easiest thing to do would be to adjust your trim (your front/back weight distribution), say by ...
