Here are some of my ideas for QoL and sailing improvement,
I really like sailing in BDO so I hope this activity will be more interesting in the future, and see some adventurers joining.

1. Improve Manage menu to make it more useful
for now, this menu is only used to view the current sailor.
in the present time players already have more than 1 ship,
I have 3, Epheria Carrack : Advance (stay on Illiya Island for bartering), Epheria Carrack : Volante (Stay on Velia for vell taxi), Epheria Carrack : Valor (Stay on Oquilla's eye for Daily Quest).
before they increased the number of cabins for sailors I didn't have a problem, because I had 17 sailors, divided for 3 ships, but since they increased it to 100, it became a problem because I always have to bother for board sailors, and have to keep them idle if I want able to board to another ship if I want to use another ship in another location

I want this menu to be "Manage Sailor" where we can, board and Disembark anywhere, and give the menu shortor group by level, type, oldest or newest, etc.

EDIT:
after I own Panokseon it is now more painful to move, disembark, board, each sailor 1 by 1 for a total of 15 sailors, I want them to make a model like "instant disembark all", and make presets for crew/sailor sets to make it easier to board more directly lots of sailors instantly, for God's sake, it would be nice for you to create a system where we are allowed to take sailors from other ships as long as they are still inside the wharf manager.

2. Sailing aesthetics

In BDO sailing is a kinda weird, the sailing ships open when they are parked, and the sails close when they sail in the middle of the ocean, I know they decided on this method because ships in the past used dipper to move, my suggestion is to make "support by wind" mode " and "mode against the wind" where the sails change direction to be slightly tilted forward. I know this is a bit difficult for the dev team because they have to overhaul several ship models that have been released.

and for ships that are anchored, or fully stopped, it's better to make it like a cog ship mode without a captain where the sail automatically closes when of Wheel.

3. New skills for Sailors with Professional rank 1 and above, (or the dev team can set it up themselves)

I suggest the name is "Captain's Flare", sailing to do Sea monster hunting to Margoria like grind Saltwater Crocodile, or Lekrasan is fun, but sometimes we are disturbed by several Sea events, storms, rain, and at night, some friends often suggest changing the setting graphic like gamma and contrast, but for me this is even boring, it doesn't impress and others, if on land we can activate firefly and Atanis firefly, but at sea these 2 functions are useless.

so that you can feel better when doing Sea monster hunting activities, the Captain is given a skill where he is able to fire a Flare at 1 point to light up the surroundings and stay there for a few minutes, maybe 3 minutes of Flare and 5 minutes of cooldown are perfect, only party members or personally for each player who can see this it all depends on the dev team's decision, and can only be cast by the captain who drives the ship, consumes the "Small atanis firefly" item in the inventory every 1x use, this is also suitable because Sea Monster Hunting sometimes makes us pull monsters getting out of the zone, this is a bit annoying because sometimes we don't know where the zone boundaries are for 1 monster, so we can mark them.

4. Skins for ships

This is just my personal taste, but I decided not to buy one of the ship skins that have been released just because there are 2 Tower models behind this,

I think this is a bit disturbing to my taste, I'm even waiting for PA to release several ships with historical skins, where more like a real ship in the real world or lifted from a movie, like a ghost ship skin.

or my other suggestion is where the Benelois Ship part set can be used in Epheria carrack, where it can be applied to all skins except prow/figurehead, because I know this can be used to abuse to hide Carrack's identity xD so just a stat is enough.

I hope the feedback can be useful for other players.
