I haven't been Bartering for too long, 2-3 weeks, but here's some advice as well as feedback from Senemedar's screenshot for OP.

Don't focus on getting your ship materials as the main priority. What I see in Sene's screenshot is someone who diligently stocked up on a variety of barter materials, so when they do Ship Material Refreshes, they maximize the materials they get. In addition to doing your sailing dailies, either solo or in a group, try not to miss a day and plan how to do the monster hunting + 5 barter/10 barter quest efficiently. Prioritize having a stock of Trade goods, then Ship Materials come naturally.

I've been stocking up on materials, not even doing Material refreshes some days. While I realize it may take me longer to get my Carrack (have Caravel and Galleas atm), I am planning on ONLY doing ship material refreshes once I am satisifed with the amount of Barter goods I have stocked up. I'm at 3800~ Barters, and I'm nearing the point where I'll switch to 2-3 Materials per day, throwing in a Barter Good here and there to refresh my stock of T5's.

Despite not doing many Material refreshes, I'm about 50% of the way to having all of my Carrack mats just from doing them once every 5-6 refreshes and doing my Sailing dailies. I highly recommend making a Galleas for anyone who wants to do the dailies solo, and crafting your own cannons at Epheria. I made them +8, and Ninesharks/BR/Cads don't give me any issue, and I'm decently fast at sea (140/125/150/150) with sailors.

At guru 1 or so with a VP you can do 100 barters per refresh. At guru 50 i think it's 103-105, so going to doubt anyone is doing 500 barters a day. Doing a material refresh, you're also doing far fewer barters as well.

1. I always want everything to be equal.

2. I always takes the opportunity when there is a 1:3 barter.

3. I always use the opportunity to exchange cheap land items -> lvl 1 items.

4. I don't have VP so after a few ship mats barter I did regular barter by the way creating lvl5 supplies (hence so many of them on ss).

5. I still have them (lvl5 ones) because I will exchange them for coins because someday I will finally start getting blue gear, and it costs a lot of coins (Starlight Hardener and Starlight Emulsifier).

Conclusion: basically I haven't earned anything on barter yet, maybe a few billion but it's only a refund of the cost of building carracks.

In total, counting from ship T1, through all materials and barter used for coins for toro, a carack costs about 80b. Adding to this how much time (and nerves) it takes for blue gear, the cost of carrack will never pay off, and those 500m a day from barter are pennies.
I wanted a carrack, I have a carrack, but in its current form, sailing and barter are of no interest to me.

false

carrack cost less than 10% of that, even if u consider time investment

here's a breakdown

https://docs.google.com/document/d/1AwYcNa-sFoGWonPGBZcmT0SUGh390atW51k_JiqEAdY/edit#

even considering different prices, it is not nearly 80b

It's not my problem that you can't calculate this correctly. Very beginning is a lie because Epheria sailboat does not cost 270m but 560m (and you forget the most important thing: someone has to want to sell you, and there are no volunteers, so you have to do it yourself, and for that you need a large amount of CP that you block on workers (at least 10-15)) and mats.

Verdant Black Stones are not free because they cost a barter item lvl 1, and each such item is even 12 lvl5 so 60m or 120m (margoria).

So: loss of a large amount of lvl1 barter on enchant gear and for other mats eg. Rock Salt Ingot. Next cost - permit. Then Caravel blue gear mats and enchant to +10. Great Ocean Dark Iron and again big barter item loss. Also you need Fiery Black Stone and Frosted Black Stone, plenty. Also many FS. Caravel blue gear repair dur cost is huge. Brilliants exchange so next barter items loss. 40 000 coins for green toro gear (carrack without it it's worse than Caravel or Galleass with blue +10). Enchant and repair dur cost for toro gear. 

And we count the costs only for advanced, volante or valor are more expensive.

Counting the TOTAL cost, i.e. materials, barter items, coins and time during which we do not earn anything, i.e. we lose, it comes out to about 80b.

Currently, it is a little cheaper and faster, but it does not change the total cost too much.

Your guide does look very thorough, so kudos to putting it together, but it is outdated and even mentions:

"This guide is for people who only want to barter for money and not progress further for better boat gear (and more efficient bartering) as well as not progress further towards a Carrack (BiS boat atm). If you have any further questions, feel free to message me on Discord."

This thread was talking specifically about going for a Carrack, not bartering for money.

Even if one is to do the Ravinia Questline to cutdown the Galleas/Caravel material by half, Saps, Barks, etc. have increased significantly. ~100m for 5000 Saps because mostly max price. Almost everything listed has doubled in price, so initial costs have changed.

I'm...in the same boat... as you. Keeping all as equal as possible and prioritizing 1:3 trades, my stock stays plentiful. I admit I have been avoiding doing Crow Coin runs for now, which I'm saving for after my Galleas Blue Gear is completed. I don't plan on upgrading that to Carrack until I buy all of the Toro gear and it's enhanced superior to the +10 Blue Gear Gall.

Glad to know I'm doing some things efficiently, since going for a combat ship first isn't the smartest route, but personally, my biggest gripes while sailing aren't if I can't maximize the amount of bartering goods I can do in one run, it's speed, agility and cannon reload.

I didn't care about barter, so volante was the first, unfortunately. But ... galleas makes daily quests for carrack mats much easier. It was only when I had volante (even with toro) that I realized that in fact this sea content is just barter and everything else doesn't make sense so I had to do advanced but having one carrack to make another is much easier and faster (especially the cheaper advanced).

Also only the blue gear really reveals the full potential of a given type of carrack so volante or valor are minimal better for crocodiles to farm mats and then use them and toro from volante to blue advanced. 

no, even if the base mats for the boat is raised in price, the guide is still not as far off as your 80b as said, the price is less than 10% of the ridiculous 80b price tag you think that a carrack cost. it is outdated for sure but it gives a baseline that shows ur figure wro g. ur info is also completely wrong considering verdant black stones cost at most 2m per. also, the first boat you only need 50% of mats due to the questline. sailboat on NA has 6 preorders only so its easily preorderable. check your market before you post. not only that, you just upgrade bartalis sailboat, worker method is outdated

stop spreading misinformation, especially when you give no backup to your basis. u said a lot of wordd that means nothing to anyone that actually know what theyre doing. as i said, even if you extrapolate the time investment into silver/hr grinding elsewhere, you still will NEVER reach close to 80b. the ONLY truthful thing in ur speal is that the repair dura cost is the bulk of the cost and that will never be relevant enough to reach ur figure. i know exqctly where ur 80b figure came from as well and it's stupid for anyone to buy everything with sea coins, just as it is stupid to consider that as the cost of a carrack

not my guide, but the guide has a part for making carrack, not to mention a big portion of the cost of carrack is the initial making of the caravel, as well as blue gear. making a carrack once you have +10 blues is simply a time gate of sailing dailies

i will admit the guides outdated but it is the only one that has anything close to a silver breakdown even if its wrong but you can update with current market price yourself as it gives you a very nice list. 

also realize the only point that i'm countering is the absurd 80b carrack cost figure that is misinformation at best.

but hey, dont take my word for it go on the bdo sailing discord and ask around yourself and check out the resource they got.
