Letīs hope this remodeling never happens! I think her exterior is pretty nice as it is and adding that height to a narrow hull would be a mistake. As with all those "modern" stern extensions that are destroying almost all yachts they are fitted to.
In my opinion, tug and icebreaker conversions is a great way of making use of old ships, but vintage yachts should only be restored to their former glory, with the modern equipment being invisible fitted in.
