{Larger Sail for Galleon}

as you can see from the picture those sail looks different depend on class of ship (Left is 1st rate Galleon in a middle  and right is brigantine )

or 

just make the galleon smaller whit a lot of gun ports to make them looks different from the brigantine.(Galleon right now looks totally 2rd-rate)

{More Sail}

i think you should have added gaff sail and jib sail that will affect the ship turn rate
