Swimming/diving faster?

[Lexbya]

It's there a way of swimming or diving faster? The other day I was playing with a friend and we got a mission in a bottle for a Underwater shrine. We found the swimming up and down very long and tedious and the treasures didn't float up so we had to go up and down several times losing 30 minutes of our life.

Are we making something wrong or this missions are just not worth it/fun?

You shouldn't need to swim up and down repeatedly. Use the mermaid statues.

Just swim down once.
As you proceed in the shrine, store your treasures in the mermaid statues.
When you have finished the shrine, return to your ship using the mermaid statue.
If no danger is around, you can go to the mermaid in the water to collect your stored treasures.
Your stored treasures will now be floating.
Harpoon your treasures.

Most of them are inside the shrines, occasionally you can find one outside. Just approach them until the interaction prompt appears, they all look the same, human sized mermaid statues with shiny white eyes, holding a trident.
