Hear me out: Why are we not letting all ship types start with even more supplies like 500 cannonballs, 150 planks and a good amount of food?
For PvE it means that you can more easily just raise anchor and get going. Reduce preparation time and get players with less time into action faster. In case of PvE and PvP encounters they will be well supplied to only worry about their skills and less about supply shortage.
For both organic PvP and Hourglass it would ensure that you can get even faster (back) into action because it is less likely to run into a supply shortage without stockpiling for ages. Especially on galleons you often end up with less than 200 cannonballs to leave your outpost. If you fight a crew that has already won a battle, chances are that they have twice, tripe or quadruple the amount of cannonballs. Those 200 run out very quickly, especially on galleons. Those fights can already take forever when both crews are stockpiled.
But many crews tend to run and bait the opponents to waste supplies because of their own shortage. These kind of fights are the most time consuming and most unrewarding for both opponents. One crew ran out of supplies and starts to keep maximum distance and send boarders in desperate attempts to turn the tides. The other crew has the choice between chasing and possibly wasting a lot of supplies for the long range chase or waiting it out on an island until the other crew comes back or gives up. This can go on for a very long time. And if the crew wins, they do not even get supplies to make up for the battle.
The only alternative would be for starting crews to stockpile on multiple outposts and sea fortresses and the same applies for winning crews because they run out of supplies.
When all crews have enough supplies to actually battle it out then it is less likely for running scenarios in hourglass. Losing a fight is less annoying because you could just raise anchor and dive again. The same applies to getting sunk by the current abundance of keg droppers - at least you could raise anchor and dive again.
It would make all kind of naval encounters (PvE / organic PvP / HG) more skill related than supply related and I really think that this would be a change with no serious disadvantages.
You can not sell supplies anyways without finding corresponding delivery quests. Abusing it in a monetary way is unlikely and unrewarding. Giving all players equal grounds (supplies) to actually battle it out instead of feeling forced to run feels like a good idea to me.
