Boat means any vessel— (1) Manufactured or used primarily for noncommercial use; (2) Leased, rented, or chartered to another for the latter's noncommercial use; or (3) Operated as an uninspected passenger vessel subject to the requirements of 46 CFR chapter I, subchapter C. Full transom means a transom with a maximum width which exceeds one-half the maximum beam of the boat. Length means the straight line horizontal measurement of the overall length from the foremost part of the boat to the aftermost part of the boat, measured from end to end over the deck excluding sheer, and measured parallel to the centerline. Bow sprits, bumpkins, rudders, outboard motor brackets, handles, and other similar fittings, attachments, and extensions are not included in the measurement. Monohull boat means a boat on which the line of intersection of the water surface and the boat at any operating draft forms a single closed curve. For example, a catamaran, trimaran, or a pontoon boat is not a monohull boat. Motorwell means any arrangement of bulkheads or structures that prevents water from entering the passenger carrying area of the boat through any cutout area in the transom for mounting an outboard motor. Motorwell height means the vertical distance from the lowest point of water ingress along the top of the motorwell to a line representing a longitudinal extension of the centerline of the boat's bottom surface, excluding keels. This distance is measured as a projection on the centerline plane of the boat. See Figure 183.3. Permanent appurtenances means equipment that is mounted or fastened, so that it is not removable without the use of tools. Seats, inboard engines, windshields, helm stations, or hardtops are permanent appurtenances. Outboard motors, controls, batteries, and portable fuel tanks are not permanent appurtenances.

Table 183.75—Weights (In Pounds) of Gasoline Outboard Engines and Related Equipment for Various Rated Power (Horsepower) Ranges Notes: 1 Dry weight is the manufacturer's published weight for the shortest midsection increased by 10 percent to account for longer midsections and additional required hardware usually not included in published weights. This weight is intended to represent the heaviest model in each power category. For boats designed with a transom height of 20 inches or less, the weight in Column 2 may be reduced by 10 percent. Recalculate Columns 3, 4, and 9 as appropriate. 2 For diesel outboards, replace the value in Column 2 with the manufacturer's published dry weight + 10 percent. 3 Running weight is the dry weight plus fluids (including 2-stroke oil) and the heaviest recommended propeller. Calculated as 5 percent of dry weight. 4 Swamped weight is 85 percent of running weight. 5 Rigging and controls include engine related hardware required to complete the installation (e.g., controls, cables, hydraulic hoses, steering pumps and cylinders).
