I would agree, BUT, Nav rule 34 "Sound and light signals" says "when power driven vessels are in sight of one another and MEETING or CROSSING within 1/2 mile .......
shall (not "may")_indicate that maneuver......
It also says, "A vessel nearing a bend...or area where another vessel may be be obscured by an intervening obstruction
shall (not "may") sound one prolonged blast"
No mention of smaller vessels being exempt from the rule. Rule 33 which addresses "equipment for sound signals" does take into account size though.
It's worth noting that the rules also say "A vessel that reaches agreement with another vessel ....by using the radio telephone...is not obliged to sound the whistle signals, but
may do so.
Again, there are real world practices, and the letter of the law. I am only trying to point out that should you have an accident, your amount of fault ( $$$$ liability) will be closely calculated by how you followed ALL the rules regardless of local custom. Make no mistake, you will be at least partly at fault because if you had followed Rule 2
Responsibility" (or the general prudential rule, or the rule of good seamanship) you would never have had the accident in the first place, so by default your at least partly at fault because you did have an accident.
To summarize rule 2, it says that if you are following all the rules and there still exists the possibility of a collision, you MUST depart from those rules in such a way that will prevent that collision. If you don't or can't, you better hope your insurance is paid up. With all due respect........Arctic Traveller
