All non tidal locks unmanned on gt.ouse, hermitage lock to denver sluice including river lark,river wissey,little ouse has no locks, a couple on the cam into cambridge.
Ely end is very straight and uninspiring but earith to bedford is absolutely lovely, st.ives bridge beats PH hands down for looks and you can get most boats under it.
As mentioned goba is worth joining for use of their moorings, great chandlery/marina at st.ives.
Pumpout facilities few and far between so quite a few sea toilets still in use, river vastly quieter than the broads so sea toilet use not such a problem, no electric points at public moorings that I know of unless they have appeared in last 8 years.
Nav authority is EA who make the BA looks like gods in their complete ineptitude to operate a navigation, annual licence also dearer than broads not that there's any regular checks or rangers.
