The hull shows a round bilge model having wide flat floors and easy bilges. There is generous flare and flam in the forward sections and rather more tumble-home at the stern than current practice shows. The tumble-home aft permits ample breadth at the water line and below, and at the same time allows the deck lines to pinch in thus getting away from the straightsidedness of the usual broad-sterned cruiser. It will be noticed that the rabbet line and the three buttock lines all show a distinct reverse curve abaft station 8. This feature if not over-done results in a very smooth wake and effectively keeps the stern from settling badly. From station 11 to the stern the rabbet and buttock lines become nearly parallel to the water line; here then is a built-in squat board. After my usual practice the sections abaft station 6 show a reverse turn. The purpose of this is to add strength to the deadwood and to provide depth inside for the better accommodation of the power plant. Even with the big Kermath motor shown the shaft angle is unusually small, 12 degrees. And the less the shaft angle the more efficient the propeller will, be.

The motor shown is a 150 h.p. Kermath Seafarer and with this Navarana will have a top speed of 18 miles an hour. There are other highly suitable motors that just fit this design; ask the advice of your local motor dealer. Others that come to mind are: Red Wing, Universal, Chrysler, Buda, Gray, Scripps and Hall Scott. Do not power this design for top speeds of less than 13 miles an hour. The model is too flat fore and aft for efficient low speeds.
