Not really. If adjusting the board was really too much hassle for you, you could just leave the boards around 1/2 way down, and accept the reduced performance, especially to windward when it's light.
Just like LAR keels, although still possibly more efficient.
But if occasionally adjusting boards is too much hassle you probably should be looking at a motor
cruiser - how would you cope with all that tedious sail handling and trimming?
