Had another disconnection at sea, and this time I can't see my boat. I think this is going to require something more than just boosting stamina while I swim around. Is there a dev command for some sort of "fly" mode, so I can find it?

Yes, a couple ways actually. See https://valheim.fandom.com/wiki/Console_Commands

Easiest is (assuming you have the -console switch on): <F5> devcommands<ENTER> fly<ENTER>. To revert to normal just enter commands in console in reverse order. While flying space bar moves you up, control moves you down... oh and make sure you are either on the ground or very close to it when you exit fly mode.. otherwise will do impromptu fall damage test.
