Hi, I'm looking at options for taking my mum on a Broads holiday and wondered if anyone has any recommendations for boats which are accessible by older people with slight mobility and major confidence issues. Mum is worried about being able to cope with the steps which on older boats are often a little challenging and also the height of the hull for getting on and off the quay. I like the look of the Broadsman type boats from Richardsons as they have much shallower steps. Does anyone have any recommendations for boats which are equally accessible? Numbers wise at least 3 of us but if the boat was on the larger side we could also invite my better halfs parents as well so a max of 5, ideally with en-suite facilities. Preference would be ok the southern Broads but happy to go anywhere a suitable boat is based. Thanks Andy
