Excellent idea , a great opportunity to put modern design and modern materials technology into a classic boat usage . To demonstrate just how beautiful a ship can be made .
Maybe solar sails ? Small Toyota sized nuclear pack for electric propulsion , air conditioning and Desalination plant . Although they will probably have a decent stock of the Malvern water on board for those with good taste .
Those big nuclear ice breakers might be a good start for a design . Nice and big almost thirty inches of armour on the front for ice breaking or whatever you want to smash through . Log jams , French fishing boat blockades . Seems everyone is building big ice breakers for the Arctic routes . Heavy icebreakers offer great stability and strength . The advantages of design of some of the bigger ice breaker is their amazing multi-purposes. Dive support . Disaster relief .
If the Gulf Stream flow were to change due to global warming most rivers in the UK might freeze in the winter and a big icebreaker might be needed to open up the estuaries for fishing .
