It was adopted for aircraft purposes because the aircraft industry *is* heavily regulated including certifications and licensing...all that we want to avoid. Aircraft are not a proper correlation to personal submarines. The proper
correlation is home-built canoes, row-boats, and powered boats; none of which is required to be identified as experimental. There is no logical argument for it when certification is the historical and existing standard. There can only be two possibilities with submarines, certified or not. Therefore, a submarine built by the best commercial fabricator on the planet, which is NOT certified, is identical to a home-built submarine in the context that they are BOTH non-certified vessels. From a regulation perspective it doesn't matter one wit, that one was fabricated in a multi-million dollar facility and the other was fabricated in a two stall garage.</div><div dir="ltr" id="yui_3_16_0_ym19_1_1500042799188_22417"><br /></div><div dir="ltr" id="yui_3_16_0_ym19_1_1500042799188_22417">Jon</div> <div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1500042799188_18530"><br /><br /></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1500042799188_18526" style="display:

Construction standards abound, and existing regulations for small craft should apply (i.e licensing over 10 HP, etc.) Operational
rules already exist in the form of the International Regulations for the Prevention of Collisions at Sea. Surfacing / diving as a special consideration would appear to be covered by the requirement for maintaining a competent watch.</div>
