Picking up on this thread, I see that Le Boat are now building a further 45 of these craft for 2017, "due to overwhelming demand", including 3 new larger sizes. See photos below.
I too thought these were ugly craft, and when boating in France two years ago, we went straight for a Norfolk built Magnifique. As we soon discovered, France is not Norfolk, and air conditioning was essential ... so on the second year, we went for a german built Mystique, which was excellent. Having now seen one of these Horizons in the flesh, I can also see their attraction !
Back on the Broads, we still own our Powles 36 centre cockpit cruiser, which we are very happy with, so i guess its horses for courses ...
