I really think you're missing out on a lot if you simply make this a sea-version of Dungeoneering as far as the explorable terrain goes. You should make it at least a possibility to sail around the waters of the existing RuneSc... Gielinor, and for once sail the distances to islands and such yourself and not just (essentially) teleport from one place to another. This would include having being able to embark and disembark on piers and other suitable places around the world.
As you'd have completed quests up to points where places become available to you, you'd be able to sail to them too. I want to sail up and down River Lum, revisit Crandor on my own boat, and most of all explore the previously undiscovered outer borders of the map.
How to stop players from sailing to areas they shouldn't be allowed to, you ask? Either bring up dialogue when they cross a certain latitude/longitude, saying: "I don't have the charts for this area yet," or prevent the player from disembarking, saying, "I don't think I'm allowed to disembark here."
