The Afina 3950 was born out of frustration. When Wayne Floe, founder of Minnesota-based Floe International, couldn’t find just the right boat, he designed his own. Now his dream boat, the Afina 3950, is in production as a semicustom with a price of about $500,000. And there is really nothing like it on the water. At first glance, this 39-foot-6-inch-long, 11-foot-beam fiberglass craft looks like a big deck boat with a house on top. Designed to stretch the season, the Grand View Cabin can be completely enclosed or opened up in various stages — open the forward and aft doors, roll down the huge side windows, and roll back the soft-top section. On the day we ran the Afina from Jacksonville to Fernandina Beach, we opened all the glass but kept the roof closed for shade, and we were very comfortable on a 90-degree day and enjoyed the bright, airy house area with great views all around. Heat and air conditioning allow the owner to further manipulate the environment and the comfort of guests. There’s a galley in the main house area, a head compartment forward to port, and access to a berth area forward of the helm. A pair of 430 hp MerCruiser Bravo Three drives pushed this inverted V-tunnel hull to a top speed of 48 mph.
