You need to provide more details of what you want to lift. In the middle distributes the load between both pontoons better but the longer horizontal arm needs to be stronger. Depending on what you are lifting it not matter at all where you put it. How you attach the lift and brace it may also be important. You don't want the lift to collapse.

Any hoist that needs to handle 200 kg needs to be engineered properly and part of that would also include attachment as well as appropriate bracing. Any hoist that large is going to also need back plate(s) at the base to handle that sized load. You would normally take a hoist rated to it's capacity then multiply that by a factor to come up with a safe working load.

Without some additional details I don't see how you could make this work properly. Speculating on a hoist that large would be dangerous.
