The bigger problem, in WotC-era D&D at least, is that in ship-v-ship combat a "combat round" of maneuvers, lining up broadsides, etc. would be measured in minutes where at the individual character level a normal round of combat is just a few seconds.
Original 1e with its 1-minute combat rounds was actually much easier to adapt for this as the combat round didn't have to be extended by all that much for it to work.
Meh. A round is a round. This isn’t a mechanical issue. It’s an issue based on expectations. Frankly one minute is still WAY too short. Actions per turn would be closer. That was the length of a round in Battlesystem for a reason.
But again it’s not a mechanical issue at all.
I want Master and Commander.
They want Conan. Or Sinbad.
How many times does Conan engage in ship to ship combat? Like almost never. In the stories, the action starts at boarding. Same with pretty much any swashbuckling pirate themed story.
So I go with expectations. Skip the whole ship to ship thing because it’s not any fun for the players.
They don’t want to do it.
