Ok.

this has been completed and uploaded to the workshop btw

the keel is because stormworks doesn't like small boats, nor does it like boat shaped hulls, without the keel it lists heavily just from the weight of the player standing on one side of it

looks good BUT i myself would not use the keel piece becus it isn't realistic and maybe move the props apart a bit but still i do like how u used the 4x1 on the back side of the ship
