ICOMIA Global Conformity Guideline for ISO and ABYC Standards sponsored by ABYC, BMF, ICOMIA, IMCI, and NMMA 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 1
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.

A.2.2. Additional Requirement Matrix Subject Heading (ISO Clause no.) Scope (1) Additional ABYC Requirements or Comment (ABYC Clause no.) ABYC H-26 covers monohull and multihull craft of any length except for pontoon boats which are covered by ABYC H-35. Inflatable boats of any speed are excluded. Craft designed and constructed solely for racing are not excluded (H-26.2) Outboard powered craft (4.1) The maximum power capacity for outboard powered boats less than 6.1m (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). 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 ). (H-26.5.1.1, H26.6 and Table 1) For outboard powered boats more than 6.1m (20 ft) length, the maximum power capacity shall be as determined by the manufacturer. (H-26.5.1.2) For outboard powered boats less than 4m (13 ft) length with remote wheel steering, transom and motorwell height exceeding 485 mm (19 in), a maximum person capacity of two and maximum speed less than 30 knots, the maximum power capacity may be determined from Table 1 or by either the Quick Turn Test or Avoidance Line Test. If the maximum speed is more than 30 knots the maximum power capacity may be determined from Table 1 or by meeting both the Quick Turn Test and Avoidance Line Test. The maximum power capacity for boats in this category shall not exceed be 30 kw (40 hp). (H-26.9) Other types of craft inboard and sterndrive (4.2.1) Other types of craft Pontoon boats (4.2.2) Power capacity label and owner s manual (4.3) The maximum power capacity for inboard and sterndrive powered boats shall be as determined by the manufacturer. (H-26.5.2) The maximum power capacity for Pontoon boats shall be as determined in accordance with H-35. The maximum power capacity for boats up to 7.9m (26ft) length powered by outboard engines shall be displayed on a Boat Capacity Label in accordance with the requirements of ABYC S-7. The maximum power capacity for boats over 7.9m (26ft) length powered by outboard engines shall be included in the owner s manual. (H26.5.1) 6
Test craft preparation (5) If the maximum installed power can be met with either single or twin engines, the single installation shall be tested. (H-26.8.1.1) If the boat is wheel steered, the quickest steering turning ratio shall be tested. (H-26.8.1.3) Outboard boats without fixed fuel tanks shall be tested with one full portable fuel tank. (H-26.8.1.5) Manoeuvring test procedures and criteria All engine installations (7) A maximum manoeuvring speed shall be determined by test for all boats that are capable of a top speed of 26 knots (30 mph) or more using the manufacturers rated power. (H-26.7) For boats with a remote steering wheel the manoeuvring speed shall be determined by the Quick Turn Test. The manoeuvring speed is the highest speed at which the craft can pass the Quick Turn Test. To pass the test the boat shall be able to execute a controlled 90-degree turn after the wheel is turned rapidly through 180 degrees. (H-26.8.3.1) For boats without wheel steering the manoeuvring speed shall be determined by the ABYC Avoidance Line Test. The ABYC Avoidance Line Test is the same as the ISO avoidance line test except that distance to the line is six times the boat length plus 2m for every mph over 30 mph (26 knots) speed. (H-26.8.3.2) Warning Label (7, Figure 2) If the manoeuvring speed determined from tests is less than the maximum speed, the boat shall be fitted with a speedometer and a warning label shall be fixed at the helm position stating the manoeuvring speed and that sudden turns above this speed may result in loss of boat control and possible injury or death. The label should refer to the owner s manual, which should contain guidance on correct boat handling. (H 26.7.4) 7
