So, whilst entirely unworried about drug interception, as a NZ person on an NZ flagged yacht:
1. - in international waters, if any vessel hailed me to stop and be boarded, I would initially refuse for reasons of time deadline/safety/weather concerns as appropriate, and if they pressed, ask them their reasons for requiring boarding. If their reasons were those stated in post #2 by StuM, then I'd stop.
2. - in international waters, if a NZ vessel (or one manned by an NZ official) identified itself and hailed me to stop and be boarded, I would initially refuse for reasons of time
safety deadline, and if pressed ask them their reasons. If their given reasons were those stated in post #2, and/or if they suspected a breach if NZ law, I'd stop. (But I am still not sure about this one as a NZ flag/NZ citizen. Would apply to US flag/US citizen though).
3. - in the national waters of a country other than NZ, and if I did not intend to go to that country, when hailed I'd do the same, but also explain my
destination was not that country and claim "right of innocent passage". The reasons for stopping would be as per 2. and/or a suspected breach of local country laws?
4. - In the national waters of NZ, I'd do what I was told without much hesitation.
5. - If any vessel identifies itself as a Naval of CG vessel and threatens force, do what they say after an initial refusal for given reasons. (There is no need to give reasons, but it is always good practice).
Does this cover it as any of the properly informed experts here understand it?
It seems that drug interdiction is not a reason to stop your foreign flag vessel in international waters. The episode (referred to in this thread) in the Western
Indian Ocean (close to Africa) where the NZ
navy stopped a vessel and seized drugs but let the crew go. I
Recall at the time the NZ press stated
piracy concerns, or more specifically (I am pretty sure) that the intell was that the drug smuggling was to finance
piracy or terror operations. To me this means the authorities were able to claim compliance with the summary given by Stu in post #2.
The only actual experience I have had of anything close to this was a bit north of Lord Howe (mid Tasman) en
route NZ to
Queensland going NNW. Around 2 am the
radar showed I was being shadowed by two vessels 8 miles astern about a mile apart. I hailed them on 16 as "unidentified vessels", giving my vessel name NZ call sign, departure port and
destination, stating as per the trip plan I had already reported, and asking them to state their intentions as to course (risk of collision). They did not respond at all, but after ten minutes or so turned due west at speed.
Then there are sometimes planes when approaching NZ from the south pac.
I think I would adopt the tactics of hailing any vessel in any waters, only excepting any where there is strong piracy risk and we were a
boat alone (which ain't gonna happen either). Be proactive.
Do people think that is still best practice?
