In reply to Rob Greenwood - UKClimbing:
> I've been in a Vivaro the two times I've been and had no problems. There's a carpark in Rackwick Bay, with public toilets a short walk away, which acts as a perfect base. The only thing you might want to check is whether or not larger vans are accommodated on the ferry, but other than that you'll be good to go.
What Rob said. You will have no problem getting a van on the ferry, it takes 40 tonne trucks.
Also, you need to take the Houton ferry because the Stromness one is passenger only and while there is usually space if you just turn up on spec, I would recommend booking if you don't want to risk disappointment.
If you haven't seen it already, there is some info on new routes on Hoy that I and others did a few years ago here: https://edwardnind.wixsite.com/orcadianclimbing
