I'd look into commercial beach wheelchairs. If you google they're out there. Bloody expensive for what they are, though. Find someone who can TIG weld aluminium and you could do it for a lot less I reckon.
The problem with that is I will have to buy a van or a ute then because my car just fits my chair and my 6'8 board with enough room left for your genral beach stuff (something like above could fit alongside my board), beach wheelchairs are wider, longer and heavier -my day chair is made out of titanium and very compact for examples..
