    OK, so answering non-existing questions is not hijacking... Understood :confused::confused:

    I have the upmost respect for you being able to communicate, as well and freely as you do in English, as it is not your native language.
    I try and fail many times communicating in Japanese, your ability to do so well in another language is impressive.

    However...
    In English, this is a question.

    If responding to this question, is hijacking, then i plead guilty m'lud. :(

    Some designers or builders have confidence, based on their experience and/or analysis and testing, that their boats are designed and built to be fit for purpose without meeting the details of a specific standard. This is most common for smaller boats. Some designers and builders are now following the relevant ISO standards.

    Builders of larger vessels may follow one of the ABS yacht standards, the Lloyds Yacht and Small Craft rules, or other classification society rules. The ABS rules are now stated as applying only to vessels over 24 m though I understand they are still followed for small vessels by some designers and builders.

    Requirements for insurance depend on the insurance company. For some boats a surveyor's report may be needed. We insured an 18 foot aluminum skiff with a 40 HP outboard built by a well known company and the only information the insurance company needed was the HIN (boat serial number), boat length, engine power and sales price.

    Seems to be as you stated:

    Whereas, as stated twice now, post by Eric here on the first page, says otherwise.

    As stated, you clearly read the question asked by Eric on page one as a non-question.
    That's your prerogative.

    Same with LR. They changed their approvals of vessels below 24m several years ago.
    They tend not to advertise that they prefer not to Class vessels under 24m. They will, if asked, but don't actually mention it any more.
    They have noted in their updated rules, not in general for vessels below 24, for below, special approvals can be requested.

    Blimey!!

    As noted I have the utmost respect for your ability to communicate so well in English. But now this is where we are getting into the nuances of language - understanding when a question is asked as opposed to just a statement. And understanding of such, is the key to any communication.

    Firstly, the reply above was because you stated, no one asked a question on page 1. Thus i re quoted your request for such for emphasis.

    Because as noted several times now, yet ignored, Eric on page 1 very clearly asked a question.

    A question which you either choose to ignore, dismiss, or do not understand the nuances of the text written.
    So, again one last time... this, is a question and as noted by you that states there was no question on page 1...says otherwise:

    Your constant electing to either ignore or dismiss this very obvious question as a non-question, is your prerogative.
    But this is a question in English. Constantly saying it is not, does not alter the fact.

    AdHoc, You are just time waster, sorry... I wish You remain alone on this forum, and enjoy reading and answering Your posts yourself :confused::eek:o_O
    You just discourage other professionals to participate in any discussion, by attacking them with Your usual demagogy.
    Now You fake my post in #62 and don't want to accept it...

    That's a no then.
    You do not see Eric's post as a question - which explains everything.

    .... and this is the way in which a possibly very interesting thread regarding structural design becomes a tangle of half-said phrases, quotes taken out of context, turning and twisting the words, etc, etc. , etc. and ends by talking about the rules that do not exist in the USA. And all because Ad Hoc screwed up talking, once again, about things that he does not know nor have any practical experience. How many threads have ended with a last Ad Hoc post that has definitely bored the participants? That does have merit, spoiling much of the threads in which he intervenes.
    Alik, as you advised me, forget him. Do you remember the sellers of hair-growing liquids that worked in the old trade fairs that were organized in the village main square?:D

    That is not correct; read Subchapter T.

    these are not standards, or rules, in many jurisdictions. They may be guidelines.
    Not to quibble over words.
    well that section does not regulate under 7 passengers, right?

    Thanks for the link. Now let's look at it.
    § 175.110 General applicability. (a) Except as in paragraph (b) of this section, this subchapter applies to each vessel of less than 100 gross tons that carries 150 or less passengers, or has overnight accommodations for 49 or less passengers, and that—
    (1) Carries more than six passengers, including at least one for hire;
    .........​
    Subchapter T only applies to vessels carrying over 6 passengers for hire (or more than 12 in some situations). Where does it apply to the vessels I listed in post #45 above?

    Correction: Carries more than 6 passengers and at least 1 for hire. So it does not apply to vessels carrying 6 passengers or less, no matter how many are passengers for hire.
