As the title indicates, the author plans to collect materials today and take a day off.

Many readers may question and think that the material is completely deceptive.

But I can pat my chest to assure everyone-it's not a lie.

Since this morning, the author has been making up for the knowledge of sailing battleships. I thought that with the author's ingenuity, I could get an overview of the sailing battleship in half a day, but I found out that the knowledge of the ship is really profound... After reading the information on the Internet for a long time, I saw it in the cloud.

So I decided to spend a whole day learning the knowledge of sailing battleships.

There should also be "ship enthusiasts" among my readers. Are there any documentaries related to "Sail Battleship" that I can recommend? It’s best to be a documentary that is very friendly to beginners like me who can’t distinguish between cruisers and destroyers, and focuses on the size and speed of the "sail battleship".
