Procedure to stand and move on top of water?

I want to make a piece of armour that when worn, it allows you to stand on top of the water (like a boat).

I have a vague idea on how to do it (using the "get block"  block) but when it comes to testing it, the player moves very slowly and cannot look around.

Does anyone have an idea on how to make the procedure work much smoother and look around (like a boat you can wear).

Thanks.
