My bad . Haven’t been good in terminology.
Totally agree different animals. AIS good when you’ve rehearsed MOB protocols with your crew but worthless if you singlehand in most instances.
GPS better for SAR but especially for the first 24hours and for single handing.
It’s rare we've had the luxury of 2 up during the night. So have had the rule if you’re going to leave the helm station to do something outside you wake someone up (last watch person up to 3h into your watch-next if in last hour of your watch) to watch you. Given we’ve bought stuff over time PFDs are set up with both AIS/GPS.
Think if you go outside 200 nm from nearest SAR station personal GPS doesn’t replace a dedicated ships GPS. The added battery power and length of broadcasting time is meaningful.
Think most SAR events are coastal. Think you and your crew are more likely to be less focused. Know most people get real business minded and focused on passage. Approach their watch as their job. Will admit when it’s just me and the bride on a nice day would have the PDFs out but not worn. Even for a 30 to 50 mile transit as we sun and chat. So think a MOB device such as. mOM-8 is key.
