In the yore of catsailing the theory for daggerboard boats was to put the center of power (the sails) over the center of lateral resistance (board) and use the rudders for steering.

Historically, along came the Hobie cats with no boards, just banana hulls. They discovered that moving the mast aft they put the load over the rudders, which then acted as daggerboards, and the boat performed much better.

The next phase of evolution was to rake the mast farther aft on boats with boards as well, moving the power aft so it would allow both the boards and the rudders to have underwater lift.

This has also fit well with the modern rig that sports a headsail of some kind (i.e., spinnaker, Hooter, Screacher) the puts more power out forward.

There are also boats with skegs near the aft end of the hull, i.e., Dart, Wave, etc., that move the center of power way aft to make both the skegs and the rudders provide underwater lift. This has also proven very effective.
