Default How do I shape the bunks to the boat hull?

I'm changing the bunks on a used trailer I bought and need some
advice. The bunks are adjustable and I have measured the position on
my old trailer and have all the supports close. The only question is:

What's the best method to curve the bunks to fit the hull? The bunks
curve up in front and that is not too hard but they also curve inward
toward the center. The bunks are very stiff in that direction.

I'm using 2x6 wet fir ( not kiln dried)

Do I get the wood wet? Use a chain to pull them into position?
Something else?

I'd like to get the shape pretty close before I try loading the boat.

18ft I/O Wellcraft w/ Cobra outdrive. Single axile trailer.

Thanks

I've got an 18' Key West on a trailer with bunks. The bunks do not appear
to have any curvature, other than that caused by the weight of the boat.
The brackets holding the bunks have three holes for adjustment. The front
bracket has the bunk in the highest position, the rear in the middle
position. The difference in height is about 2". There is no angling of the
bunks towards the centerline of the boat.

If pictures would be helpful, let me know and I'll take some. It would have
to be tomorrow at the earliest.
