Moved to Norfolk and decided to sell nb and go Broads cruising. Worst days work we ever did and now back with a narrowboat on the Great Ouse (but back to canals next spring). Broads are crowded in summer and only about 130 (I think) miles are available to cruise, assuming you can get under all the bridges. If you want lock free then I recommend ( as did an earlier poster) the Great Ouse and its tributaries. There is also a bonus here, if you keep the narrowboat you can always take a trip up on to the canals should you so wish. Broads are great for a week or two but as a constant cruising ground they soon become boring. You will also feel at home on the Great Ouse as there are many narrowboats. Be prepared though, neither the Broads or the Great Ouse have an infrastructure to compare with the canals.
