ICOMIA Global Conformity Guideline for ISO and ABYC Standards sponsored by ABYC, BMF, ICOMIA, IMCI, and NMMA Author: Wieger de Wit Guideline Number 5 Powering 1. PURPOSE These documents were created by an international working group for use as a companion to the standards listed below. The creators of these documents assume the users familiarity with either the ABYC or ISO standards. 2. SCOPE The information is presented in two separate yet similar Annexes. The annexes provide additional requirements in order to assess conformity to a parallel standard from another standard system. Access to the parallel standard is required to achieve compliance with that standard. A.1 ABYC + ISO additional requirements = ISO compliance A.2 ISO + ABYC additional requirements = ABYC & USCG compliance
GLOBAL COMPLIANCE APPENDIX A.1 POWERING ABYC + ISO ADDITIONAL REQUIREMENTS = ISO COMPLIANCE A.1.1. Referenced Standards This document shall be used in conjunction with the following standards: International Organization for Standardization (ISO): ISO 11592:2001 Small craft less than 8 m length of hull - Determination of maximum propulsion power rating 1 Scope This International Standard establishes the requirements for determination of the maximum propulsion power rating for engine-driven small craft with a length of hull of less than 8 m. This International Standard is not applicable to: - personal water craft as defined by ISO 13590; - canoes and kayaks; - inflatable boats, as defined by parts 1 to 3 of ISO 6185, except that ISO 6185 3 requires rigid inflatable boats (RIBS) capable of a maximum speed of 30 kn or more to be tested in accordance with ISO 11592; - racing boats: craft designed and constructed solely for competitive racing. This International Standard does not specify craft constructional strength requirements related to maximum rated power and does not guarantee security from instability under all conditions of seaway, wind, wakes and waves. American Boat & Yacht Council (ABYC): H-26 POWERING OF BOATS July 2006 26.2 SCOPE This standard applies to boats propelled by machinery including catamarans. EXCEPTIONS: 1. Inflatable Boats (see ABYC H-28, Inflatable Boats); 2. Canoes and Kayaks (see ABYC H-29, Canoes and Kayaks); 3. Pontoon Boats (see ABYC H-35, Powering and Load Capacity of Pontoon Boats) H-35 POWERING AND LOAD CAPACITY OF PONTOON BOATS July 2005 35.2 SCOPE This standard applies to all pontoon boats powered by machinery. EXCEPTION: Boats containing Enclosed Accommodation Compartments.
A.1.2. Additional Requirement Matrix Subject Heading Additional ISO Requirements (ABYC Clause no.) (ISO Clause no.) Scope (H-26.2) (H-35.2) Pontoon boats pontoon boats are covered by ABYC H- 35, Powering and Load Capacity of Pontoon Boats Inflatable boats inflatable boats of any speed are excluded Determination of maximum power for outboard powered boats less than 6.1m length (H-26.6) Racing craft - craft designed and constructed solely for competitive racing are not excluded (1) The maximum power capacity for boats with outboard engines less than 6.1 m (20 ft) length shall be as given in H-26 Table 1 (horsepower), derived from a factor calculated by multiplying the boat length overall (ft) by the transom width (ft) ISO 11592 Annex C can be used to calculate the maximum power capacity (in kw) equivalent to H-26 Table 1 requirements for boats with a factor greater than 5.1 (m 2 ) For boats with a factor less than 5.1 (m 2 ) use H-26 Table 1 to calculate the maximum power capacity. (4.1) Determination of maximum power for outboard powered mini sports boats less than 4m length with wheel steering (H-26.8.3) Manoeuvring speed tests All engine installations (H-26.7) If the maximum power determined from the manoeuvring speed tests described below is less than the power calculated with Table 1 (or Annex C where appropriate) the maximum power shown on the capacity label shall not exceed the manoeuvring speed tests power For outboard powered boats less than 4 m (13 ft) length with remote wheel steering the maximum power capacity may be determined by the Quick Turn Test method in lieu of Table 1 provided that the transom and motorwell height exceed 485 mm (19 in) and the maximum person capacity is two. The maximum power on the capacity label for boats in this category shall be 30 kw (40 hp) (4.1) A manoeuvring speed shall be determined for all boats that are capable of a top speed of 26 kn (30 mph) or more using the manufacturers rated power If the manoeuvring speed determined from tests is less than the maximum speed of the boat the manoeuvring speed and related information shall be shown on a warning label at the helm position. Boats with steering wheel (H-26.8.3.1) Boats with other steering systems (H-26.8.3.2) For boats with a remote steering wheel the manoeuvring speed shall be determined by the Quick Turn Test For boats with any other steering system the manoeuvring speed shall be determined by the Avoidance Line Test or the manoeuvring test procedures of ISO 11592 (4, 5, 6, 7, Annex A)

A.2.2. Additional Requirement Matrix Subject Heading (ISO Clause no.) Determining maximum power Outboard boats ABYC S-30 Reference Tables IA and IB Additional ABYC Requirements (ABYC clause no.) For outboard boats the maximum power shall be determined by the manufacturer, complying with the quick turn test and avoidance line test. In all cases the power capacity shall be stated on the boat capacity plate and be included in the manual NOTES: 1. Dry Weight is the manufacturers published weight for the shortest midsection increased by 10% 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%. Recalculate columns 3, 4 and 9 as appropriate. 2. Running Weight is the dry weight plus fluids (including 2-stroke oil) and the heaviest recommended propeller. Calculated as 5% of Dry Weight. 3. Swamped Weight is 85% of Running Weight 4. Rigging and controls includes engine related hardware required to complete the installation (e.g. controls, cables, hydraulic hoses, steering pumps and cylinders). Calculated as 5% of Dry Weight. 5. If the boat is equipped with a permanent fuel system and is not intended to use a portable tank, the portable fuel tank weight may be omitted, provided that the weight used is not less than 33 CFR part 183, subpart h, Table 4, Column 6. For monohull boats less than 20 ft. (6.1 m) in length, Title 33 CFR Part 183.41 requires that the boat be tested with the weight of the full portable fuel tank as shown in Column 8. 6. For diesel outboards, replace the value in Column 2 with the manufacturers published dry weight + 10%
