In respect of whee you can access the main cabin, (but not where the steering position is),this bears similarities to our Flamingo, with the only access from a cross deck immediately in front of the original engine room.
The problem being that if you can't get BOTH ends against the bank, then you can't get that cross deck particularly close either - something our now ageing dogs struggle to cope with.
It also means when we do events or festivals where we have to breast up, and not against the bank, we are severely limited in options, because we need to align with something on the other boat where the dogs can cross.
All far more of a problem on a 3 footed drafted boat than a 2 foot drafted one, of course, but i suspect the owner of this "interesting" boat will find occasions where they would be better off if it were accessible from an end.
