For exendingvthe swim platform I would suggest you would need to find a boatyard that does the relevant work.

As for the switches it's a matter of trial to see what the switches do. eg wipers, horn, nav lights.

Yes. I asked about the switches because a while back someone else was providing another with the details. Some of them don’t seem to do anything which is what I was trying to find out.
Thanks
