Suggestions/Comments: As it stands out, the Hollow Maretta is just a search for "a needle in a haystack". I don't know if she is dead or not and since I don't have a carrack with full +10 blue gear, nol and good innocent sailors (4.0+ speed) it takes a lot of time sailing all of Margoria.
Make a widget like Black Shrine telling if she's dead or not and show on what channel is it like:
"Hollow Maretta: Spawning in xx:xx - <Channel name>
Hollow Maretta: Spawned <Channel name>". For the hearing impaired, add a visual representation when they enter the area in which Hollow Maretta is or simply make the Hollow Maretta a weekly mission where after you take the quest from Oquilla Eye it shows on the map the exact location.
As hard as i try i don't see how suggesting going to help OP at all, its going make even harder for him to compite with players who farming it now, unless OP magically think that other players stop doing it or let him do it.
Adding her to the hunting widget is enough, I think, so people would know if she was up or not on that channel.
If you keep an eye on System chat, you can tell when she is killed in your channel. She respawns an hour after that.
Sailing Discord has a channel for callouts as well, so you know which channels are on cooldown.
You're best bet honestly is not trying to focus on finding her, until they fix or improve something. She seems to spawn along barter routes, so do your dailies and she will eventually show. My guildie and I both found her several times near Haran Cargo ship. We both have +10 Blue gear Carracks though.
This is a great tool for sailors, and I do admit the way of making it compared to other tools is much more difficult. But take the suggestions others have made, discord, server chat, and it should improve your chances.

This WILL make it harder for OP to compete, a widget will only make it so Red Sailors can camp at spawn points, or other more geared sailors can get there faster. She hits pretty hard if you can't evade her attacks/have a slow boat.
