I think there is a rating modifier for installing wings on a boat not so equipped. But what about hiking racks?
My father is past the age of trapping, so I am considering a rack setup for the helm position. His feet would still be on the hull, so it wold be pretty much the same as trapping in regards to righting moment. I would still trap as crew. I do not think the racks should be penalized the same as wings since you are not hiking off the end.
