I have a water-ballast Hunter 26 with a Mercury 9.9 outboard. The boat does not reach hull speed under power so I am going to put a larger motor on the boat. Does anyone have personal experience with a 15 or 20 hp outboard motor on the Hunter 26?What speed can you reach under power? I have noticed that the hull is more like a semi-displacement hull than a displacement hull. The bottom is shallow and rounded near the bow and flattens near the stern. In addition, the displacement/length ratio is 175 which makes it a very very light cruising sailboat. I am expecting that the boat will not only achieve hull speed, but will actually exceed it under power.Again, has anyone actually tried this? Thanks
