NR 5.12 Note Note: The volume of integral structure aft of the transom below the static float line may be added to the calculated cubic capacity.
NR 5.12(3)(a)5. 5. The weight capacity for the craft shall then be the sum of the weight for passengers plus the weight for the maximum horsepower motor for which the boat is recommended, full fuel tanks and operating equipment.
NR 5.12(3)(b) (b) A substitute method for determining the weight capacity of pontoon boats may be applied to pontoon boats having only one deck. The deck must be within the width of the pontoons, must be no more than 6 inches above the pontoons, its length within the railings must be no more than 80% of the pontoon length, must not overhang the pontoon, and must be capable of draining overboard freely. If the boat complies with these conditions, the weight capacity shall not exceed one half of the reserve buoyancy of the boat which shall be determined by subtracting the weight of the vessel including the weight of the maximum horsepower motor for which the boat is recommended, full fuel tanks and normal operating equipment from the buoyant force of the boat's pontoons or similar flotation devices.
NR 5.12(4) (4)Passenger capacity. The recommended passenger capacity of those vessels covered by s. 30.501, Stats., shall be determined by the following equations, using whichever is less: - See PDF for table PDF
NR 5.12(5) (5)Linear measurements. In the preceding paragraphs of this section all linear measurements are taken outside planking or plating and recorded in feet with decimal equivalents for inches and eighths, all volume measurements in cubic feet and all weight measurements are in pounds.
NR 5.12(6) (6)Maximum safe horsepower capacity. The determination of maximum safe horsepower capacity of outboard equipped motorboats less than 20 feet in length covered by s. 30.501, Stats., shall be calculated by the use of the following formulas:
NR 5.12(6)(a) (a) Step 1. Measure length of vessel (midline measurement) and the width of the transom (or back of the boat) (across the top), recording in feet and inches. Convert inches to hundredths of a foot (Table 1). Multiply length times width to determine FACTOR. For .5 or above round off FACTOR to the next higher whole number. If FACTOR number is between 0 and 52, use Table 2 to determine maximum safe horsepower capacity in calm water.
Table 1 - See PDF for table PDF
Table 2 - See PDF for table PDF
NR 5.12(6)(b) (b) Step 2. If FACTOR number is larger than 52.0, the safe outboard horsepower capacity is figured according to the type of steering and the height of the transom. Measure transom height in inches (measure from bottom of keel to lowest point of the transom). For outboards with remote steering and a transom height of at least 20 inches, multiply the FACTOR by 2, subtract 90 and raise the answer to nearest multiple of 5. The resulting number is the maximum safe horsepower in calm water.
NR 5.12 Note Note: Following are examples of how to raise answer to nearest multiple of 5:
NR 5.12 Note If the second numeral in your answer is a 5 or a 0, DO NOT CHANGE ANSWER.
NR 5.12 Note If the second numeral in your answer is 1, 2, 3, or 4, change it to 5. For example, 21, 22, 23, or 24 would all be changed to 25.
NR 5.12 Note If the second numeral in your answer is 6, 7, 8, or 9, change it to a 0 and raise the first numeral by 1. For example, 26, 27, 28, or 29 would all be changed to 30.
NR 5.12(6)(c) (c) Step 3. For outboards that do not have remote steering or the transom height is less than 20 inches, multiply FACTOR by 0.8, subtract 25 and raise the answer to nearest multiple of 5. The final answer is the maximum safe horsepower in calm water.
NR 5.12(6)(d) (d) Step 4. For flat-bottomed, hard chine (where the side meets the bottom) outboards that do not have remote steering or the transom height is less than 20 inches, multiply FACTOR by 0.5 and subtract 15, raise answer to the nearest multiple of 5, the final answer is the maximum safe horsepower in calm water.
NR 5.12 Note Note: The above formulas and tables used to determine maximum safe horsepower capacity for outboard motorboats appear in 33 CFR 183.53.
