The EA guarantee navigation from April to September and guarantee certain rights ,ie anchor anyway in river moor at locks etc ,after 30 September no guarantee. My mooring is in tidel just after Richmond half lock, l need no licence ,l only buy one to go to non tidel.l can go out when l want in tidel , l don’t need vhf because l under 30 feet and half powerful engine ,never had a problem with PLA ,Infact rarely see them this far up river once in blue moon they visit teddington.If you can’t go anywhere how come they say you must move every 14 days ,if a lock don’t work on thames courts have said they can’t make you move or fine you till lock works again,mind you that don’t stop district enforcement trying .Last year l sent my licence to lock keeper so when the EA give my address to district enforcement for mooring fees they go lock keepers house not mine ,this year they not send me licence but l paid on debit so don’t really care if l anit showing it l no l got it .
