Some Ideas: Ships and LiveStock

I was talking with my brother awhile ago and we both agreed that there needs to be a way to travel across the water with large loads and more people ( about 15 people). I'm talking about big ships like Barcas or Caravels. There would need to be a skill to make ports so ships could dock, it could be called "ship hands" or something like that. I would also like to see some sort of battle mechanism built specifically for ship battling, including: cannons, rams, and ways to board other ship by force and to be able to capture them. Another part of this i would like to see is the introduction of different ship types like merchant ships, which would go faster and could have more goods capacity, and battle ships that would obviously be more suitable for battling. It would also be pretty cool if you could do mass fishing in turn making fishing that much more a trade. Another idea that I had was that the use of livestock should be implemented somewhere in this game. I'm talking about sheep, cows, horses and pigs. They could be sold to markets as a commodity for meat, transportation, breeding etc. I think it would help with moving many things if there was a way for cows to be able to carry way more than a player or a sled could carry (like about 10 boxes) and you could have three follow you at a time.
