I have not seen the "Handicap Hoist" referred to at the Glendaale docks so I can't offer an opinion as to it's functionality.
Wheelchair vans are common enough and seem to work fine..
Owned and Operated by the owner of the van, who has been instructed as to how to use that particular device. On rare occasions I have seen them in use. Each one is tailored to the persons particular challenge.
I would think such a generic (one size fits all) device
"Owned" by the town would pose a real liability risk to the town, if say the
private individual in a wheelchair was accidentally dropped into the lake...whether through operator error, mechanical malfunction, or just plain bad luck.
NB
PS: It's not like you are transfering a person in a wheelchair from an stationary van to a solid parking lot. Small boats have a nasty and oftentimes unpredictable habit of
Moving when weight is transferred around.
