Bigger Boats To Make Oceans More Fun

Oceans are big and annoying to travel over with the current small boats we have. So I thought of bigger boats that could be large enough to walk on like the happy ghast and have storage and a crafting table and bed and furnace, and even able to attach dispensers to it to fire arrows or maybe even tnt, this could also be fun on small boats too. They would have a lot of health and if broken you don't get most of the stuff back, this makes small boats still useful because the big ones are mostly bound to one ocean. They also could be made repairable if needed, and you would craft with a banner, for the sail, and parts that could be found in shipwrecked maybe like a helm and hulls and stuff like that. The sail would keep the same design as the banner to make the ships more customizable and the ships themselves would still be smallish like 5 by 9 blocks or something similar and look like shipwrecks. It's always bothered me that shipwrecks exist, saying that big boats could be possible but Mojang has never given us a functional one, this could also make oceans more fun because you can explore and fish and fight with many friends and have naval battles, but still mostly for oceans because small boats would still be good for like a quick river cruise and ice boats.
