Totally understandable! There’s a boat at the dock right in front of the spawn point! The R key is for primary interactions so you can use that to hop on. From there, left mouse button hold selects the left oar, right mouse button does the same for the right oar, and then making circles with your mouse rows. You can also hold tab and look around to interact with stuff in the boat. Full controls including gamepad are also on the game page so hopefully that helps too :)
