The size has alot to do with the sound. I have a QB lil boat paddle, very similar to your MAD cherry bomb, and it is a very high pitched. I also have a QB 10 sider and you can move the top paddle around to 10 positions to make it longer shorter and side to side. Each move you make with the call has a different pitch. How your paddle makes contact with that surface makes a differance in pitch as well. Your battleship is a longer call so it will cut the wind better (so I hear). Alot has to do with the make up of the call. One piece or multiple glued or has those plastic inserts holding it together. The type of wood its made from the different grains will affect volume. Also the thickness of the paddle, thinner ones will be higher then the thicker ones. For me it has seemed that the little boxes have a much higher pitch and the bigger the frame the lower the pitch is. As far as leigth goes I dont have any real long ones so i cant accuratly speek to that. Hope this helps.
