Hi Guys,
Thanks for the replies thus far, I've been diligently contacting weathered sailors of varying degrees of experiences from hard core racers to cruisers and in between. Consensus is overwhelmingly to sail over the top and down the west coast mostly due to the unpredictability of the weather and lack of safe harbour in the Bight. Migrating whales and tides also considered, but it looks like thongs and t-shirts rather than jumpers, boots and foulies

The boat is in very good order and will be surveyed prior to handover. Not expecting to need to add much more than fuel, water, food and charts.
I won't be sailing it back solo because I don't know the boat well enough and although it's fitted out with nice gear, I don't know whether the boat has been fitted out with adequate redundancy for long distance cruising if something should fail, or the solar panels don't feed enough charge to keep fridge and autopilot and nav all running at once.
All this shall be revealed in due course. I'm still awaiting technical specs on the boat such as sails, fuel tank size, water tank sizes, battery capacity etc. It all looks good, but will feel better when I know the stats.
Really looking forward to a great adventure. Feel free to contact me via PM Toph. I'm NOR.
Thanks again for your considered responses

Fair winds,
Salty
