NavList:

I have thought about boxes. C&P offer what they call "rough cases" (waterproof, shockproof, floatable) with some of their new sextants. Looks like an attractive solution. If I find a (used) sextant that I like and take to sea, I might try getting something like that and adapting the padding (which is the challenge with generic "rough cases" bought separately).

That is probably a Peli or B&W case. I recently purchased a Davis 15, and while I drooled over the C&P case, but not wanting to double the total price I instead got a generic knock-off "!Peli" ("NotPeli" in programming shorthand) case. Almost certainly not as durable, nor as waterproof, but at 20-25% of the cost it was more reasonable. Being a paranoid old b*gger I will sticker it with reflective tape (SOLAS grade?) on all sides: if I ever have to abandon ship in the dark, and grab stuff in a split second panic^Wrush, then making it easy to spot might make the difference, and it might then concievably come in handy.  Hmm, there might be space in there for a small GPS (Garmin Foretrex), some Li batteries and a simple kamal as a sextant backup.

One in a million chance/risk it will happen, and we all know what they say about one in a million chances...
