1.19 added chest boats, but I wanted more. So "Boat with Everything" allows you to put pretty much any block in the game into a boat.

• Shift right click on the boat to add the block.
• Punch the boat to remove it.
• Many blocks (including barrels, chests, ender chests, droppers, dispensers, lecterns, looms, cartography tables, stonecutters, crafting tables, grindstones, smithing tables, flower pots, concrete powder blocks, banners, carpets, sponges, TNT, redstone lamps, note blocks, campfires, doors, trapdoors, fence gates, anvils, and metal storage blocks) have special appearances or behaviors.
  • Try opening your inventory while riding the boat.
  • Try shift-right clicking to interact with the block.
  • Try driving next to a redstone power source.
