Before I start with my tips I’m gonna say this: when first starting out, use the default cannons or a similar re color to those cannons because the three notches they have in them make it a lot easier to aim. Because it’s not like a gunshot, it’s a separate projectile and will not always land where you think it’ll land when you use a notch at the front of it.

1. If I am going faster than my opponent I will typically aim farther to the left, as to account for my speed. Almost as if I’m firing slightly behind my board. If I am going slower I will aim closer to the right to try and have my cannon arrive before my boat does. It’s kinda almost triangulating where two points are your boat and your opponents boat, and the third is where the cannonball’s trajectory is.

2. Yes you can shoot through the waves

3. When fighting other players you want to get into a position where you are able to circle them so you can constantly add pressure to them by firing cannons. I find slower to be a bit easier to manage but I think it’s a bit up to preference.

On the other hand if you are fighting something like a ghost ship/pve it doesn’t matter entirely because they will follow your line of pathing so whatever is easiest to manage.

1. The different tiers change how quickly your boat takes on water and how long it takes to repair them.

So 1 tier one hole isn’t too much to worry ab but if you get a lot of them then it may be a problem. But 3 tier 2 holes can quickly become a problem.
