Lets start off the Sailor Cannons are arguably the best cannons in the game due to their size allowing for most additional vision. In addition they are the most universal cannons in the game, the cannons that no one has an excuse to not be used to using. They are the default and best cannons at that and one of the only cosmetics on the ship that actually matters since having a cannon your crew is used to is important so that they can consistently make line ups and hit their shots.
There is currently only 1 reskin of the sailor cannons being the golden sailor cannons which are currently unavailable and I am in no way saying they should be made available again. However it is getting really boring using only the sailor and golden sailor cannons on all my ships.
Fix is easy just make more reskins of the sailor cannons! Can we have silver ones for example, or red? So many colors so many options here! But just make sure they are reskins of the nicest and most used cannons in the game!
Now please no one say you can get used to other cannons, which is 100% true, but I cannot expect every time I play with new players they will be used to playing with some other cannon that me and my friends are however one can expect everyone to be used to the default sailor ones!
