3. Where deemed appropriate by the Society, ISO, KS or internationally recognized standards consid- ered as equivalent may be applied for the items which are not specified in the Guidance. Fire pro- tection and fire extinction are to be complied with the requirements of Flag Administration in addi- tion to the Guidance.

102. Classification

1. Recreational crafts built and surveyed in accordance with the Rules of the Society(hereafter referred to as "the Rules") or with the alternatives equivalent to the Rules will be assigned a class notation by the Society and registered in the Registration Master.

2. For the classification of recreational craft the requirements, not mentioned in this chapter, are to be in accordance with Pt 1 of Rules for the Classification of Steel Ships.

3. Recreational crafts classed with the Society are, for continuation of the classification, to be sub- jected to the periodical and other surveys, and are to be maintained in good condition in accord- ance with the requirements of this Guidance.
