You can't beat the Hunter's Yard boats for sailing performance. Built in the 30s thay are basic and have no engine but ghost along in no wind, can tack up narrows rivers and shift along amazingly in a breeze. Martham boatyard now have some of the old Norfolk Broads Yacht Co boats including America and Palace(?), as well as their Japonica's etc. A yacht one day I'll take with my beautiful wife is Zoe - built in the 30s (or before) Zoe is a very nippy small yacht with a cozy little cabin for romantic getaways for two.
If the White Moth is still on hire...well, she is stupendous. 65' wherry yacht. IF Cherub buddies wanted a good group holiday she sleeps 8-10 and shifts like nothing else on the Broads. Makes fast yachts look slow.
I've done big boat sailing but always enjoy (prefer?) the Broads because it's highly technical sailing, no real danger (not like navigating at sea) and there's always a pub to tie up near if you want that or complete solitude if you want that.
