When Sailing is released, the plan is that it will be gated behind the quest 'Maiden Voyage'. It will then open up a whole bunch of new map-areas. So, then, a natural question: will any additional quests be released simultaneously with Sailing, to help fill in those map areas, analogous to how there's a quest-release planned to happen as part of the Varlamore release-update?
If, in the eventual Sailing Release, the quest-behind-which-Sailing-is-gated is called something other than 'Maiden Voyage', the question will be resolved based on whether any quests aside from that one, whatever its name ends up being, come out simultaneously with Sailing. If it ends up being released without being gated on any quest, resolution will be based on whether it comes out concurrently with at least one quest which isn't primarily structured as a beginner-level introduction to the Sailing skill.
@Gen If they do, this question will still resolve based on whether any quests other than Maiden Voyage come out concurrently with Sailing, it just will happen to be the case that all quests that come out concurrently with Sailing will be quests other than Maiden Voyage. :p
