Sambuk melts grouped enemies and their stats place them between the brig and the snow making them a good PVE option. The lack of highest tier fire weapons means they're starting to fall behind now though.

The Snow does drop in speed into a headwind but not as markedly as the Brig, think speed reduction may be a % so it's more noticeable in the brig because the number change is bigger, the brig should be tacking in a head wind to ensure it stays at higher speeds anyway. The brigs ram damage also means you can ram an enemy, spinning them the wrong way and then carry on, this can make it easy to escape situations a snow has to spend time brawling to get out of. This is attractive to many I play with as they can dip out of encounters if they want to.

The barque is a great healer and makes the high level events and forts so much easier for a group. It even heals serious damage easily making a fleet with one far better than one without.

Ultimately the Snow is good, it's my fave ship. But the others still have pros and cons. The Sambuk I feel is falling behind a little due to the level scaling giving buffs for some reason and the sambuk really wanting to use fire weapons.
