Very much so, moving a rib on a four wheel trailer is hard work.
If you loose one wheel on a four wheel trailer will the remaining wheel and axle take the full weight? I don't know but looking at the tyre ratings I doubt it, and on my 4 wheel trailer it would mean the remaining axle taking nearly 100% overload, so either way your not going far if you loose a wheel on a four wheel trailer with a boat on it.
Finally the cost. A 1500 kg axle from De Graff is £350, or £700 for a pair.
