But considering how many Nords and Redguards are vikings and pirates respectively, it can be assumed that they've got a lot of sailing experience.
The Altmer had already been sailing all over Tamriel and beyond back when the most advanced humans were the Nedics, they've got generations of experience over anybody else in seafaring alone, plus they're great in battle as well...
It also seems I've managed to completely isolate this topic to one debate alone in terms of the RP's lore accuracy. A few other points I might mention in regards to it:
-I can't see establishing 'colonies' in Yokuda being a big priority for Hammerfell, not only are there people already in what's left of Yokuda but if I remember correctly they're already trading with them anyway.
-Moving the capital to Sancre Tor is unlikely, the IC is too important geographically and metaphysically.
-"To improve economic migration... and to prevent another continental war" is not really a reason why other provinces would submit to a new government.
-Highrock is not a "land of magicians", that's Summerset if anywhere.
-How is it that Skyrim, one of the provinces with the most military history, has a lower military ranking than Argonia which has never really been known for any organized military efforts?
Sten the Ugly mentions that Nords like ships and sailing.
Yes, because if Sten the Ugly mentioning that Nords like ships isn't hard evidence for their seafaring prowess, nothing is...
