What if someone lost connection, wants to join back but someone took over his helm? Your suggested solution guys would cause too much mess.
If you have a loss of connection in the first place, you either had a blackout or was lagging too much, I, using myself as test subject, found that a lagging captain is not a useful captain.
Recovering from a blackout takes time, and, unless everyone is behaving like a sniper, in that time the battle could have already ended.
If you got disconnected for the lag, then is better not to reconnect as you may keep lagging and cause more trouble than not.
One of the better captains I've flown under, Waffleghost, was flying with 600ms+ Ping.
Perfect galleon positioning.
Deal with it. 
I still don't fully understand this witchcraft thingie that is the ping.
I usually end up in America servers, 220+ ping, no problems, 9 times out of 10
I end up even more usually (since I'm in Europe
) in the European server and with barely 80 ping the worst case of "Dragonballs of Icarus Z" happens.
I mean, it's not that it doesn't happen also on the american servers, but, come on! 80 ping and everyone starts teleporting around, with people being randomly disconnected?!?
I even flew sometimes with 400+ ping and nothing happened!
Also, these are perfect cases where you see shenanigans like
"Disable that Mobula there, don't let it turn!" *lag happens*
"Where the hell is it now...?"
"
IT'S BEHIND US CAPTAIN""Well, fuck"
