Yes as CC says, low bridges no problem, shallow water no big problem, it would be fine on breydon but I wouldn't fancy taking it out to sea but it would probably be ok in good conditions with a decent engine on the back.
One bit to watch on normans is the wood inside the transom (sandwiched in the grp), worth a few drillings from inside to see if it's good or rotten/water soaked, not a big problem up to about 10hp but dodgy with a bigger motor hanging on it, you can cut out and replace from inside and re-glass over if needed but best checked before fitting cockpit out so you have good access.
