The heavier the tounge weight, the less oscillation. This has been my experience towing with large pick-ups and duallys (towing 5th wheel campers to large powerboats). I can shift the weight around and see quite a dramatic difference with the cat as well as the rest.

I have mine just heavy enough so I can lift it but not so heavy that I cannot move it around. Stability while towing is a must. I personally would rather have the tounge a little heavy and have the stability while towing.

Dont just use someone elses figure to try to figure out what your tounge weight should be. All of these trailers are a little different (not to mention what you tow it with).

Is it possible to move the boat back some? Are you having problems towing now, or is it just too heavy for you?

Moving the axle may be a good idea. It does'nt take much!
