Those following our journey south in our sailboat, Scarlet, from the Uk to Portugal know that we've been at it a few years. 2 years ago we left Gosport and eventually reached Quiberon in Brittany before we were stopped by our starter motor catching fire(!). We did engine repairs and maintenance there and overwintered for a year until last summer when a somewhat delayed start due to ADHD diagnosis getting in the way saw us reach Bilbao, where we spent last winter.
This year, when the weather allowed, we started moving again. We have now reached Muros in Galicia.
We knew this section, getting round the Galician rias, was going to be a race against time. It's an indented coastline with no safe shallows with treacherous rocks everywhere. If you stick to deep water you avoid it.
But every summer some of the population of Iberian orcas that spend winter and spring around the Strait of Gibraltar migrate north to Biscay to follow bluefin Tuna. And the only way to reliably avoid them is to stay in water of less than 20m depth. This is impossible in Galicia.
Our time has run out. Orcas have now been spotted north of Lisboa. They have arrived. We are still 3 rias from the Portuguese border.
So now we may be stuck, or at least have to watch VERY carefully for a window to JUST BLOODY RUN.
I'm part of the "orcas.pt" fleet, which is a group of mostly hobbyist sailors banding together to share information and advice about the orca situation. The "official" recommendations are terrible to the point that experts mostly prefer to work with our group, and as a result we get pretty good intel on where they are (some of them have GPS trackers I believe, but that exact info is only shared with the group admin because we don't want people looking for these animals).
Here's the rub. Orcas swim (when they aren't chasing something) at up to 50km per day. We have a pretty good read on where the danger areas are. Last sighting, draw a 50km circle for each 24 hours. Are you in it? Be afraid.
Almost no attacks have ever happened west of the 10th line of longitude, but we can't reasonably go out there in Scarlet. She is a 9 metre marina hopper absolutely not equipped for deep ocean sailing. Some people do cross the Atlantic in boats like that but they're nutters.
Also she is a deep fin keel with a single spade rudder; it will take very little orca action to pull our rudder clean off at which point there is a hole below the waterline that the rudder stock exited through and ... well, the boat sinks.
Unfortunately smaller sailboats with spade rudders which are most at risk from sinking on the first hit are amongst their favourite playthings. Contrary to the popular "orcas are going after the billionaires" narrative, the boats they trend to take are likely worth less than your car if you have a half decently paying job. Big motor yachts tend to steer by thrust vectoring and don't do "floating thing go spinny when I smack the shit out of its tail fin". They can also quite possibly outrun them which we absolutely cannot.
And then you abandon to liferaft after, assuming they haven't taken out your electrics (the batteries are back there), doing the whole mayday mayday mayday please send a fucking helicopter, I think these marine sheep spawn are going to eat me, HELP! thing (we have a handheld radio as well and iPhones can send distress signals even without cell coverage).
So anyway there you are in your liferaft, watching a load of your stuff go to the seabed, all three of you (probably. We usually have 3), throwing up (because throwing up in a liferaft is what you do. They are profoundly unpleasant spaces to spend any time), which surrounded by playful teenage delinquent 6 tonne murderfish who you have heard are VERY picky eaters and will only eat bluefin tuna and maybe octopus and definitely not human, honest, but which aren't above violently tossing floating shit around into the air for the lulz to see if it makes more fun vomiting and screaming noises, hoping that you don't drift into the rocks on what is literally called the "Coast of Death" when you translate the name into English.
So we're gonna like, properly pay attention to the "orca forecast", as it were.
And if we aren't absolutely certain it's safe to run for Vigo as fast as we fucking can, we may be stuck in Muros until autumn.
Let's see. Worst case we get the boat hauled out onto the hard and re-antifoul her (disgustingly messy but strangely pleasurable job).
if the worst does happen, assuming your boat is still floating and controllable after the first hit, apparently the thing to do is disengage autopilot, start the engine if not already running, apply FULL throttle, and motor directly away from the pod (preferably towards shallow water) as fast as possible. They can swim faster than the boat can go, but remember, they're juveniles doing it for a laugh, and apparently if they wander off from the pod by more than about 300 metres their mothers yell at them to come back.
"Aw mum! I was sinking the thing!"
"You can sink the thing after you've eaten your dinner, now come HERE"
"Dinner is tuna again. It's always tuna. I'm BOOOOORED. Can I have beef?"
"What the fuck is beef?"

(Truth in advertising, I love Elvanse but I wish they'd stop lying about how long it lasts and stop pretending adults are fine on the same dose as an eight year old)

in reply to Sarah Brown • • •FWIW, I'm pretty sure Elvanse's duration is dose-dependent. My last uptitration step was mostly to make sure that my evenings would be reliably covered when I take it in the morning.
AFAIU, its pharmacokinetic curve has three main components: the cleavage of the lysine dimesylate, which probably typically takes just one to two hours; the exponential decay curve of renal clearance after the amphetamine has become free in blood and gotten stocked up by the synapses, and some sort of effectiveness threshold. The exponential decay curve interacts with the effectiveness threshold in ways that are non-linear and can be non-intuitive to one who hasn't dabbled in calculus. But both components vary between people.

in reply to Riley S. Faelan • •@Riley S. Faelan My experiences:
30mg - started working in the first hour. Abruptly and violently ended 6 hours after that.
50mg - started working in the first hour. Abruptly and violently ended 7 1/2 hours after that.
70mg, which I've been taking for 14 months now - starts working in the first hour. Peaks about 3 hours in, sometimes with the propensity to make me just want to stare at the wall because it's very interesting and brain go quiet, for a bit, sometimes does fuck all. Ends moderately abruptly 7-8 hours after I take it.
At which point I take 10mg dexamphetamine sulphate which works in about 90 seconds and lasts 3 - 3 1/2 hours.
At which point I take 10mg dexamphetamine sulphate which works in about 90 seconds and lasts 2-3 hours.
And then I stop, unless I need my emergency "It's a long fucking day and I have to keep going for a bit longer" dose of 10mg dexamphetamine sulphate which works in about 90 seconds and lasts about an hour.

You can see where this is going.
Honestly, I'd rather they cut the crap and just gave me 50mg dex a day to do with as I will but Oh No ThErE Is A dAnGeR oF DiVeRsIoN AnD HypErTeNsIoN.

in reply to Sarah Brown • • •This kind of sounds like your metabolism causes rapid swings, and the effectiveness threshold might be on the low side. Do you happen to know if taking, say, 30mg in the morning and 30mg in the aftrnoon, before the first dose runs out, might produce a friendlier curve in you?
Blood pressure of ADHD people going down on amphetamine is pretty common, AFAIK. The NT explanation is, it's because treating the ADHD reduces stress, but I kind of suspect that, at least in some forms of ADHD, the "paradoxical" effect of stimulants is directly applicable, kind of similarly to how RightHormones often directly improve a trans person's brain functions and happiness.

in reply to Riley S. Faelan • •@Riley S. Faelan Yeah. It's definitely not due to lower stress. I *HAVE* lower stress, but different stimulants affect me differently in terms of blood pressure.
Caffeine - mild effect on ADHD, blood pressure goes up.
Amphetamine - huge effect on ADHD, blood pressure goes "standing up is now FAFO"
Ephedrine - effect on ADHD comparable to caffeine. Blood pressure *craters*
That last one must utterly piss off anaesthetists.
I've tried splitting my Elvanse dose. It just weakens the first one and the second one does piss all. Elvanse 30 contains more dexamphetamine (eventually) than Amfexa 10 but the latter gives me 3 - 3 1/2 good hours and the former gives me 2 hours of "meh" (both after 70mg of Elvanse).
The whole "stimulants do the same in ADHD and non ADHD people once you account for the different baseline" thing is such obvious bullshit, brought to you by the same people responsible for such classics as "Only boys get this", "Only children get this", "This is never comorbid with autism", and, "emotional disregulation is not a symptom".
