Hi! I drew a new, smooth texture, if you like it / want, you can feel free to use in your mod.

Textures:

Maybe I'll touch them one time for a little. Just to match the square-ish-shape, like minecart with chest

Thank you for your work, I'll think about it!

Hey! What do you think?

Looks nice, could you maybe make one for a furnace? Needing one for a later update maybe ( O_O )

Oki-doki
Hope furnace boat doesn't burn itself xd

Which is better?

bottom because the furnace is not lit by default

yeah, i know, but lit variant is lit =)

Take them :)

By the way, I found vanilla boat textures in your assets files. Textures I did works perfectly without them, so If you will replace them textures, you can also remove boat textures from assets to ease customizing/resource-pack-making things tho.

Model Item for example:

{
  "parent": "minecraft:item/generated",
  "textures": {
    "layer0": "item/acacia_boat",
    "layer1": "boatcontainer:item/chest_boat"
  }
}
