Thanks John, It would seem we were given the said leaflet which I confess I did read. My problem is I have too many navigational aids (Nicholsons, WaterExplorer, e-canal mapp, CanalPlanAC etc) and this particular leaflet and it's info got over-looked in my confusion. I'm guessing the elsan points are noted as 'Tip out facility' on the leaflet (what else could it be). Also it seems they have re-names all the locks differently to the Nicholsons just to confuse me even more... Doesn't take much these days!
