Yes I did check out the Polaris, at their factory, not with sea trials. They make two boats in the 4.5 neighborhood, both fairly deep vee, 22 degree deadrise, actually same hull. The boats are, by the factory's description "overbuilt" and are no doubt bulletproof, the only downside being weight. Bill at the factory spent most of a morning with me and answered a multitude of questions. I am planning on going on a demo ride with him in a 15'6" "contender" rib in a week or so. I'll report.
