Regarding another camera, I already have the Nikon 1 AW1 with WP lenses: I started this adventure out with this astonishing little camera & it took most of the pics I've posted here. I was gifted the D7200 when a very encouraging & published Japanese photographer insisted I needed to upgrade for the Alaska stage. I use the AW1 whenever it's damp or when we are in the dinghy or hiking up creeks to booming waterfalls. It's spent 3 years in severe tropical heat & humidity, and been underwater or in pouring rain (I made a hood for it) many times & still shoots flawlessly after 3 years of significant abuse. But it has limits.
I have been avoiding the 70-300 for 2 reasons: I already have the Nikkor 55-300 VR - so close, yet so far from what I need so I'd be accumulating over-lapping gear; plus I find it hard to tell which of the 5 versions is being offered on various sites. The 18-400 is a little like this: I already have a Nikkor 18-140 VR and an 11-16 f/2.8 Tokina, but I'll read up more on it.
I will not be returning to the US so unless I buy through UHH used is more risky than new. At least with new (non-gray) I may have time to claim warranty & send for repair etc when I can.
After 4 months solid learning & research I was seriously considering the Tamron 100-400 f/4.5-6.3 Di VC USD. The aperture starts out at 4.5 & doesn't ratchet up as early as any of the comparable lenses; it's light; I already have filters to fit it & I can get it for $599 new with 12 mths warranty. It doesn't get slammed in any review I've found although it is rated slower for tracking speed sports than others. That seems OK as I'm not interested in shooting fast action sports (except the one-off Iditarod - but no lighting fast motor sports!!).
BUT - I will take another look at the 18-400, as then maybe I don't need to change lenses too often.
The thing is, I'm a novice with an outstanding camera: maybe with a few more years experience I will get better results without such heavy reliance on gear (& you guys!). But this voyage is full of one-off experiences - we will never come this way again. Plus I never expected anyone would be interested in my story or pics, it all just sort of grew & I was unprepared - so, for now, it seems like having the right gear will help.
Thanks all so much again. I will let you know how it all goes!

You say you already have a Nikon 55-300mm. I can tell you that the AF-P DX 70-300mm others have suggested is a much sharper lens at the long end, and sharper also than the 18-400. You can buy that 70 -300 for less than $150 grey market online, which is how I got mine and what I suggest. Bargain! Very snappy auto focus and VR (stabilization) In my experience shooting thousands of shots on my own rocking boat 300mm on a DX camera is near the limit you would be able to handle.
