What're the odds that we get an ocean achievement diary?

I know we're still due a Varlamore one, and I would ideally want that one first while Jagex works out the issues with Sailing, but I think it could be pretty good.

We already have checklists of tasks to do: chart all the things, park your boat everywhere, build all the things on the islands you land on. It would also definitely have to include using new training methods, gathering the new resources, fighting the new monsters, doing the trials, salvaging everywhere, finding all the schematics, etc. Stuff you've already done like building boat parts and facilities, and stuff you'd want to do like drink an Armadyl brew while in Kree's room in GWD.

In my mind the rewards should include a flag for your ship per tier, to add more variety. Also, for the people who are already 99, why not let them fly their skillcape as their flag?

While on the boat, the flag could do things like buff your boat's HP and / or defence slightly, increase the radius of salvaging very slightly, increase the radius of picking up trial crates slightly, increase the chance of sea-based random events slightly, or something to make trawling more fun (I haven't unlocked trawling yet so idk what it could be).

Other rewards could include a new crew member, reduced boat recovery fees, increased healing from repair kits slightly, new trim paints, putting your family crest from construction on your sail, or other weird cosmetics like gold trim for your hooks and nets.
