Suggestions/Comments: It would be an interesting addition to make an upgrade for the guild galley.

Basically make it like the Capotia Elephant, where you use a [Guild] Galley mount voucher in the guild hall crafting.

For it to be meaningful it would need to be able to hold a candle to a carrack, but since it's a guild mount it should still necessitate the use of players on cannons to compete. To that end, one could make the cannonballs hit hard as hell, but since a player has to be on it and controlling the cannon the act of landing a shot would be much harder, balancing the bonus damage against actual player skill.

This would allow guild galleys to be relevant as something other than a respawn point for Vell and target for pirates griefing Vell. It wouldn't magically make the galley able to kill any pirate, since players would actually have to land a shot against a skilled pilot firing from the helm, but it would make it a little more interesting for both sides. It would also make the galley an actively desirable component of sea monster hunting as a guild.

tl;dr: Add an upgrade for guild galley like guild elephant, make it hit really hard but still require players on cannons.
