New E56XO Model Unveiled By Horizon Yachts Horizon Yachts is delighted to announce a brand new model called the E56XO. You’d be right if you thought it had anything to do with their very popular E56 model. In fact the E56XO is based directly off the E56 using its widespread appeal while working towards those who like the more sporty form-factor. Horizon says the E56XO has been designed primarily for the Australian market but it is easy to see how this yacht could easily have world-wide appeal. This isn’t one of those concept yachts that stay stuck to the design boards, this yacht is currently under construction.
